This paper describes a short distance telemetry network which measures and relays time, space, and position information among a group of ground vehicles. The goal is to allow a lead vehicle to be under human control, or perhaps controlled using advanced autonomous path planning and navigation tools. The telemetry network will then allow a series of inexpensive, unmanned vehicles to follow the lead vehicle at a safe distance. Ultrasonic and infrared signals will be relayed between the vehicles, to allow the following vehicles to locate their position, and track the lead vehicle.

Abstract:
Driving a safety critical task that requires a high level of attention and workload from the driver. Despite this, people often perform secondary tasks such as eating or using a mobile phone, which increase workload levels and divert cognitive and physical attention from the primary task of driving. As well as these distractions, the driver may also be overloaded for other reasons, such as dealing with an incident on the road or holding conversations in the car. One solution to this distraction problem is to limit the functionality of in-car devices while the driver is overloaded. This can take the form of withholding an incoming phone call or delaying the display of a non-urgent piece of information about the vehicle. In order to design and build these adaptions in the car, we must first have an understanding of the driver's current level of workload. Traditionally, driver workload has been monitored using physiological sensors or camera systems in the vehicle. However, physiological systems are often intrusive and camera systems can be expensive and are unreliable in poor light conditions. It is important, therefore, to use methods that are non-intrusive, inexpensive and robust, such as sensors already installed on the car and accessible via the Controller Area Network (CAN)-bus. This thesis presents a data mining methodology for this problem, as well as for others in domains with similar types of data, such as human activity monitoring. It focuses on the variable selection stage of the data mining process, where inputs are chosen for models to learn from and make inferences. Selecting inputs from vehicle telemetry data is challenging because there are many irrelevant variables with a high level of redundancy. Furthermore, data in this domain often contains biases because only relatively small amounts can be collected and processed, leading to some variables appearing more relevant to the classification task than they are really. Over the course of this thesis, a detailed variable selection framework that addresses these issues for telemetry data is developed. A novel blocked permutation method is developed and applied to mitigate biases when selecting variables from potentially biased temporal data. This approach is infeasible computationally when variable redundancies are also considered, and so a novel permutation redundancy measure with similar properties is proposed. Finally, a known redundancy structure between features in telemetry data is used to enhance the feature selection process in two ways. First the benefits of performing raw signal selection, feature extraction, and feature selection in different orders are investigated. Second, a two-stage variable selection framework is proposed and the two permutation based methods are combined. Throughout the thesis, it is shown through classification evaluations and inspection of the features that these permutation based selection methods are appropriate for use in selecting features from CAN-bus data.

Collecting and analyzing vehicle performance data is an essential part of the launch process. Performance data is used to determine mission success. Performance data also provides essential feedback to the launch vehicle design engineers. This feedback can be used to improve the overall vehicle design and thereby improve the probability of a successful launch. Various Telemetry products are used to gather and process critical information on board launch vehicles. Data is transmitted by RF links to fixed or mobile receiving stations. These Telemetry products are ruggedized for the extreme launch environments. This paper discusses the use of video telemetry as a means of providing launch vehicle performance data.

Frequently a requirement exists to track sounding rockets or balloons from remote locations which have no radar capability. Occasionally, there is also a requirement to provide an alternative to radar tracking at those locations where it exists. TRADAT VI satisfies both requirements by providing vehicle positional from telemetry. In addition, it also provides real-time trajectory plots by its graphical display.

Abstract:
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada
The Multi-Vehicle Metric & Telemetry System (MMTS) is a complete range system which performs real-time tracking, command destruct, and telemetry processing functions for support of range safety and the test and evaluation of airborne vehicles. As currently configured, the MMTS consists of five hardware and software subsystems with the capability to receive, process, and display tracking data from up to ten range sensors and telemetry data from two instrumented vehicles. During a range operation, the MMTS is employed to collect, process, and display tracking and telemetry data. The instrumentation sites designated for operational support acquire tracking and telemetered data and transmit these data to the MMTS. The raw data is then identified, formatted, time tagged, recorded, processed, and routed for display to mission control and telemetry display areas. Additionally, processed tracking data is transmitted back to instrumentation sites as an aid to acquire or maintain vehicle track. The mission control area consists of a control and status console, high resolution color graphics stations, and large screen displays. As the mission controller observes mission progress on the graphics stations operational decisions can be made and invoked by activation of the appropriate console controls. Visual alarms provided my MMTS will alert mission control personnel of hazardous conditions posed by any tracked vehicle. Manual action can then be taken to activate transmission of the MMTS vehicle destruct signal. The telemetry display area consists of ten fully-functional, PC compatible computers which are switchable to either of two telemetry front end processors. Each PC can be independently set up by telemetry analysts to display data of interest. A total of thirty data pages per PC can be defined and any defined data page can be activated during a mission. A unique feature of the MMTS is that telemetry data can be combined with tracking data for use by the range safety functions.

HammerShark é um veículo resultante de um projeto pluridisciplinar na Universidade de Aveiro, envolvendo várias áreas tais como mecânica, electrónica e informática. O veículo foi desenvolvido com o objectivo de participar na Shell Eco- Marathon, uma prova académica com o intuito de desenvolver e testar veículos ecológicos. O vencedor é a equipa que percorre a maior distância, utilizando a menor quantidade de energia. O HammerShark introduziu algumas inovações, tais como o CAN bus com um interface Bluetooth, permitindo que todos os parâmetros do veículo e da prova possam ser obtidos através deste. Em todas as provas motorizadas, o sistema da telemetria _e uma parte fulcral para atingir o sucesso no evento. Com o aparecimento de dispositivos móveis, que utilizam sistemas operativos open- source, abriu-se a possibilidade de utilizar este tipo de dispositivos como meio de suporte aos sistemas de telemetria. Nesta dissertação propomos um novo sistema de Telemetria { DroidShark, para o HammerShark - baseado no Android OS. Com o suporte por parte do Android para comunicação inter- processos entre aplicações third- party, foi possível desenvolver uma arquitetura modular capaz de concretizar todos os objectivos propostos. O DroidShark _e composto por duas unidades - car unit e pit unit -, onde o car unit comunica com o HammerShark e é responsável por providenciar todos os dados recolhidos á pit unit, por forma a informar todos os restantes membros da equipa que se encontram na pit lane. O DroidShark demonstra que a incorporação de dispositivos móveis em sistemas de telemetria é uma solução com grande potencial.
HammerShark is a vehicle, resulting from a multidisciplinar project from University of Aveiro involving work from several areas such as mechanics, electronics and informatics. The vehicle was build with the aim to participate in the Shell- Eco Marathon, a challenge for college students to design build and test energy efficient vehicles. The winner is the team that covers the farthest distance using the least amount of energy. HammerShark introduces some innovations, namely the CAN bus with a Bluetooth Interface for publishing data through it. On every race challenges, the telemetry solution is a fundamental part in order to achieve success in the event. With the introduction of the CAN bus, a new and improved telemetry system could be developed to assist the decision of the driver and/or the crew during and after the race. With the emergence of mobile devices, using open {source operating systems, a new door was open to develop new telemetry systems based on these kind of devices. In this dissertation we propose a new telemetry system - DroidShark, for the HammerShark vehicle - based on Android OS. Since Android OS supports inter- process communication between third- party applications, it was possible to develop a modular architecture to achieve all proposed goals. The DroidShark is composed by two units - car unit and pit unit -, where the car unit communicates with HammerShark and is responsible to provide all acquired information to the pit unit, in order to inform all remaining team members that stand at the pit lane. DroidShark demonstrates that incorporating mobile devices in telemetry solutions have a significant potential.

This paper describes a telemetry system for a high-powered rocket entered in the Intercollegiate Rocket Engineering Competition hosted by the Experimental Sounding Rocket Association. On-board the rocket GPS coordinates,acceleration, magnetic field and lux readings are collected,along with other data. The data is sent between internal systems using commercial Internet-of-Things boards that utilize IEEE 802.11 wireless protocols. The aggregated data is transmitted to a ground station through a monopole transmitting antenna and custom designed helical receiving antenna such that in the event of a crash, data is not lost. The ground station data recovery is performed using a commercial XBee transceiver, before being displayed in real time for tracking and safety purposes,and stored for future data analysis. The target apogee is 9 km, so real time GPS data will be useful for both tracking and vehicle recovery operations.

This paper describes a telemetry and command communication link used as part of a rover entered in the University Mars Rover competition. The link is capable of transmitting multiple real time video streams, along with other telemetry data from a rover to a base station approximately one kilometer away, under non-line-of-sight conditions. Low data rate commands are sent to the rover, to control its movement. To simulate conditions on Mars, the link cannot use existing cellular or satellite communication infrastructure. The data link uses the 70 cm Amateur Radio band for transmission in both directions.

Unmanned Air Vehicles (UAV's) provide a low-cost, low-maintenance, and effective platform upon which experimentation can be performed to validate conceptual aerodynamic ideas. However, the UAV flight test data acquisition process is complex and requires a reliable recording system for post-flight data analysis. The thrust of this thesis was the development, construction, and validation of a viable telemetry system for data gathering and processing. Major areas of focus were: integration of the telemetry into a 1/8-scale model, radio-controlled F-16A airplane; telemetry circuitry optimization; recording and display of instrumented parameters; and data reduction techniques necessary to obtain useful information. A test flight was flown and data were gathered using a steady-heading side-slip maneuver to demonstrate successful integration of all supporting elements.

Launch vehicle equipment reliability is driven by infant mortality failures, which can be eliminated using a prognostic analysis prior, during and/or after the exhaustive and comprehensive dynamic environmental factory acceptance testing. Measuring and confirming equipment performance is completed to increase equipment reliability by identifying equipment that fails during test for repair/replacement. To move to the 100% reliability domain, equipment dynamic environmental factory testing should be followed by a prognostic analysis to measure equipment usable life and identify the equipment that will fail prematurely. During equipment testing, only equipment performance is measured and equipment performance is unrelated to equipment reliability making testing alone inadequate to produce equipment with 100% reliability. A prognostic analysis converts performance measurements into an invasive usable life measurement by sharing test data used to measure equipment performance. Performance data is converted to usable life data provides a time-to-failure (TTF) in minutes/hours/days/months for equipment that will fail within the first year of use, allowing the production of equipment with 100% reliability.

Unique vehicle designs encourage the use of the builder to complete its own failure analysis. Current failure analysis practices use telemetry and diagnostic technology developed over the past 100 years to identify root-cause. When telemetry isn't available speculation is used to create a list of prioritized, potential causes. Prognostic technology consists of generic algorithms that identify equipment that has failed and is going to fail while the equipment is still at the factory allowing the equipment to be repaired or replaced while it is still on the ground for any spacecraft, satellite, launch vehicle and missile.

The U.S. Air Force's next generation reusable booster (NGRSB) offers the opportunity for the Space Command to use intelligent equipment for decision making replacing personnel, increasing safety and mission assurance by removing decisions from program management personnel who may not have had any flight-test experience. Adding intelligence to launch vehicle and spacecraft equipment may include requiring the builder to use a prognostic and health management (PHM) program. The PHM was added to NASA's aircraft programs in 2009 and we have requested NASA HQ and NASA Marshal Space Flight Center adopt the NASA PHM in the procurement contracts used on the new Space Launch Systems, NASA's congressionally mandated replacement for the Space Shuttle. Space Vehicle Program managers often make decisions for on-orbit spacecraft without ever having on-orbit space flight experience. Intelligent equipment would have eliminated the catastrophic failures on the NASA Space Shuttle Challenger and Columbia. These accidents occurred due to the lack of space vehicle subsystem engineering personnel analyzing real-time equipment telemetry presented on strip chart and video data prior to lift off during pre-launch checkout for the Space Shuttle Challenger and the lack of space vehicle real-time equipment telemetry for Columbia. The PHM requires all equipment to include analog telemetry for measuring the equipment performance and usable life determination in real-time and a prognostic analysis completed manually will identify the equipment that will fail prematurely for replacement before launch preventing catastrophic equipment failures that may cause loss of life.

Abstract:
Generally, a ground telemetry station for launch vehicle (LV) has tracking function only; therefore, position measurements depend on radar. Time of arrival (TOA) and angle of arrival (AOA) are typical location techniques for emitting targets. In this paper, we propose a Combined TOA and AOA localization method for LV using two ground stations. When transmitter (Tx) time is not known, it is necessary to make virtual onboard timer for TOA estimation. The virtual onboard timer generates time stamps of streaming frame according to data rate. First station which is located in space center has no tracking function. But it can generate the virtual onboard timer. Second station has tracking function, so it generates AOA information. By solving sphere equation(s) of TOA from at least one station and a line equation of AOA, target position in three-dimensions (3D) can be obtained. We confirm the localization performance by means of comparison with an on-board GPS of a real launch mission.

Emerging and next-generation test instrumentation increasingly relies on network communication to manage complex and dynamic test scenarios, particularly for uninhabited autonomous systems. Adapting wireless communication infrastructure to accommodate challenging testing needs can benefit from reconfigurable radio technology. Frequency agility is one characteristic of reconfigurable radios that to date has seen only limited progress toward programmability. This paper overviews an ongoing project to validate a promising chipset that performs conversion of RF signals directly into digital data for the wireless receiver and, for the transmitter, converts digital data into RF signals. The Software Configurable Multichannel Transceiver (SCMT) enables four transmitters and four receivers in a single unit, programmable for any frequency band between 1 MHz and 6 GHz.

Satellite and launch vehicles continues to suffer from catastrophic infant mortality failures. NASA now requires satellite suppliers to provide on-orbit satellite delivery and a free satellite and launch vehicle in the event of a catastrophic infant mortality failure. A high infant mortality failure rate demonstrates that the factory acceptance test program alone is inadequate for producing 100% reliability space vehicle equipment. This inadequacy is caused from personnel only measuring equipment performance during ATP and performance is unrelated to reliability. Prognostic technology uses pro-active diagnostics, active reasoning and proprietary algorithms that illustrate deterministic data for prognosticians to identify piece-parts, components and assemblies that will fail within the first year of use allowing this equipment to be repaired or replaced while still on the ground. Prognostic technology prevents equipment failures and so is pro-active. Adding prognostic technology will identify all unreliable equipment prior to shipment to the launch pad producing 100% reliable equipment and will eliminate launch failures, launch pad delays, on-orbit infant mortalities, surprise in-orbit failures. Moving to the 100% reliable equipment extends on-orbit equipment usable life.

Prognostic technology uses a series of algorithms, combined forms a prognostic-based inference engine (PBIE) for the identification of deterministic behavior embedded in completely normal appearing telemetry from fully functional equipment. The algorithms used to define normal behavior in the PBIE from which deterministic behavior is identified can be adapted to quantify normal spacecraft telemetry behavior while in orbit about a moon or planet or during interplanetary travel. Time-series analog engineering data (telemetry) from orbiting satellites and interplanetary spacecraft are defined by harmonic and non-harmonic influences which shape it behavior. Spectrum analysis can be used to understand and quantify the fundamental behavior of spacecraft analog telemetry and relate the behavior's frequency and phase to its time-series behavior through Fourier analysis.

This paper suggests a reconfigurable sensor network (data bus) which is well suited for telemetry mission of rockets and launch vehicles. Reconfiguration of sensors’ channel information can be achieved without additional software and hardware. The proposed network consists of a central unit and multiple remote units with RS-485 data bus. Since those units need only an FPGA and a programmable ROM to be implemented, the network can provide minimum costs and high reliability. And this paper also presents reliability prediction result of a unit based on MIL-HDBK-217F and Monte Carlo simulation.

This thesis explores the design and development of a cost-effective, easy-to-use system for remotely monitoring vehicle performance and drivers' habits, with the aim of collecting data for vehicle characterization and traffic shaping. Vehicular congestion and concerns over fuel reserves, pollution, and carbon emissions have recently emerged as prominent sociopolitical concerns. These problems are formidable, but could be addressed more fruitfully with better information about vehicles and drivers habits, leading to policies such as vehicle-specific congestion charging or an odometer-based road tax. Despite the proliferation of sensors in cars, data is often hidden due to the antiquated nature of the federally-required On-Board Diagnostics (OBD). Systems to log and process such data exist, but no well known reconfigurable systems augment OBD with additional sensor data and transmit it over a cellular network. This thesis proposes a system wherein vehicles become distributed sensors, each transmitting a rich supply of information. The standardization of OBD and decreasing cost of bandwidth make now an opportune time to develop a real-time logging system. Inexpensive processors make it possible to provide privacy through onboard calculation, obfuscating much personally-identifiable data. This document discusses the planning process, experimental configurations of hardware and software, results, and conclusions associated with the development of a cellular diagnostic system capable of supporting an "app" model for information feedback. I present a Bluetooth-OBD logger, a cellular logger, and a web interface capable of representing live and historical data from vehicles, including example applications for calculating congestion pricing. This project proves the feasibility of capturing data using a remotely reconfigurable controller area network (CAN) to general packet radio service (GPRS) interpreter, visualizing the information in real-time, and writing applications to make use of the incoming data. The hardware and software were proven successful in meeting the goals set for the project. The hardware proved robust, gathering data without issue for hundreds of miles. The sample data demonstrated low bandwidth use, identified network weaknesses, and pointed out issues with the currently-legislated OBD standard. This thesis closes by exploring future possibilities suggested by the development of this system, including wireless odometry and next-generation OBD.

Telemetry Prognostics is Failure Prediction using telemetry for launch vehicle and satellite space flight equipment to stop launch failures, launch pad delays, satellite infant mortalities and satellite on orbit failures. This technology characterizes telemetry behaviors that are latent, transient, and go undetected by the most experienced engineering personnel and software diagnostic tools during integration and test, launch operations and on orbit activities stopping launch pad delays, launch failures, infant mortalities and on orbit failures. Telemetry prognostics yield a technology with state-of-the-art innovative techniques for determining critical on-board equipment remaining useful life taking into account system states, attitude reorientations, equipment usage patterns, failure modes and piece part failure characteristics to increase the reliability, usability, serviceability, availability and safety of our nation’s space systems.

Two separate imaging payloads were successfully operated using a wireless line-of-sight telemetry system that was developed as part of a recently completed UAV (unmanned aerial vehicle) imaging campaign over the largest coffee plantation in the USA. The objective was to demonstrate the performance of “off-the-shelf” wireless technology in an effort to reduce the cost of line-of-sight telemetry for imaging payloads on UAVs. Pre-deployment tests using a conventional twin-engine piloted aircraft at a flight height of 10k ft demonstrated successful broadband connectivity between a rapidly moving (ca. 280 km hr^(-1)) airborne WLAN (wireless local area network) and a fixed ground station WLAN. This paper details the performance of the wireless telemetry system on a slow-flying (<50 km hr^(-1)) solar-powered UAV at a flight height of 6.4 km.

One of the long term goals of Autonomous Underwater Vehicle (AUV) minehunting is to have multiple inexpensive AUVs in a harbor autonomously classify hazards. Existing acoustic methods for target classification using AUV-based sensing, such as sidescan and synthetic aperture sonar, require an expensive payload on each outfitted vehicle and expert image interpretation. This thesis proposes a vehicle payload and machine learning classification methodology using bistatic angle dependence of target scattering amplitudes between a fixed acoustic source and target for lower cost-per-vehicle sensing and onboard, fully autonomous classification. The contributions of this thesis include the collection of novel high-quality bistatic data sets around spherical and cylindrical targets in situ during the BayEx'14 and Massachusetts Bay 2014 scattering experiments and the development of a machine learning methodology for classifying target shape and estimating orientation using bistatic amplitude data collected by an AUV. To achieve the high quality, densely sampled 3D bistatic scattering data required by this research, vehicle broadside sampling behaviors and an acoustic payload with precision timed data acquisition were developed. Classification was successfully demonstrated for spherical versus cylindrical targets using bistatic scattered field data collected by the AUV Unicorn as a part of the BayEx'14 scattering experiment and compared to simulated scattering models. The same machine learning methodology was applied to the estimation of orientation of aspect-dependent targets, and was demonstrated by training a model on data from simulation then successfully estimating the orientations of a steel pipe in the Massachusetts Bay 2014 experiment. The final models produced from real and simulated data sets were used for classification and parameter estimation of simulated targets in real time in the LAMSS MOOS-IvP simulation environment.

Spacecraft and launch vehicle reliability is dominated by premature equipment failures and surprise equipment failures that increase risk and decrease safety, mission assurance and effectiveness. Large, complex aerospace systems such as aircraft, launch vehicle and satellites are first subjected to most exhaustive and comprehensive acceptance testing program used in any industry and yet suffer from the highest premature failure rates. Desired/required spacecraft equipment performance is confirmed during factory testing using telemetry, however equipment mission life requirement is not measured but calculated manually and so the equipment that will fail prematurely are not identified and replaced before use. Spacecraft equipment mission-life is not measured and confirmed before launch as performance is but calculated using stochastic equations from probability reliability analysis engineering standards such as MIL STD 217. The change in the engineering practices used to manufacture and test spacecraft necessary to identify the equipment that will fail prematurely include using a prognostic and health management (PHM) program. A PHM includes using predictive algorithms to convert equipment telemetry into a measurement of equipment remaining usable life. A PHM makes the generation, collection, storage and engineering and scientific analysis of equipment performance data "mission critical" rather than just nice-to-have engineering information.

The aircraft, satellite, missile and launch vehicle industry suffer from catastrophic infant mortality failures rate at ~25% even after exhaustive and comprehensive factory acceptance testing is completed causing unreliable systems, program delays and cost overruns. The discovery of the presence of deterministic behavior in equipment analog telemetry generated during factory acceptance testing preceding all equipment failures, which is identifiable using prognostic analysis, eliminates infant mortality failures resulting in increased equipment reliability, lower program cost, shorter test and delivery schedule and increased equipment usable life ensuring mission success. The addition of a single, embedded analog telemetry measurement to all active equipment allowing all equipment to be identified during factory testing that fails, and all equipment that will fail within the first year of use, to be identified will allow vehicle builders to lower program cost, use less equipment, use less testing and have a shorter delivery schedule and more reliable equipment and longer equipment usable life expanding the use of telemetry to identifying equipment that will fail well into the future.

Instrumenting the operational B-2 Strategic Bomber presents some unique problems. For example, the requirement to remain operational dictates that the aircraft must retain its stealth characteristics. This means traditional antennas cannot simply be attached to the airframe. A solution to this problem is an antenna designed with stealth, or Low Observable (LO), attributes. Stealth is not an absolute; it is relative. Therefore, antenna design becomes a balancing act between the LO relativity, antenna directivity, and antenna gain. Weapons testing is an additional concern, where instrumented ordinances transmit data that must be monitored real-time prior to launch. Stealth vehicles must carry weapons internally, restricting the Radio Frequency (RF) transmission of telemetered data from the weapon. With the development of future stealthy conveyances, such as the F-22, Joint Strike Fighter (JSF), ground, and ocean-going craft, these concerns will become even more prevalent.

A aquisição de dados das variáveis químicas e físicas da água de lagos e reservatórios é de extrema importância. Monitorando a qualidade da água distribuída e consumida em nossas cidades estamos protegendo o nosso recurso natural mais valioso e conseqüentemente nossas próprias vidas. Esse monitoramento na atualidade ainda se realiza de forma bastante convencional e trabalhosa. Esta dissertação apresenta o desenvolvimento de um sistema de telemetria de dados e vídeo completo entre uma plataforma autônoma para coleta de dados hidrológicos e uma estação de trabalho em terra. Este sistema fará uma composição com outros projetos já desenvolvidos nesta área de pesquisa, como a embarcação convencional utilizada como plataforma autônoma com seus motores, sensores e atuadores; a sonda de coleta de dados, responsável pela aquisição das variáveis químicas e físicas da água; sistema de posicionamento, que utiliza um GPS e bússola eletrônica para orientação, atuando e coletando dados dos sensores da embarcação; e sistema de gerenciamento, responsável por definir e orientar quais os pontos de coletas a serem pesquisados. Foram desenvolvidos algoritmos de comunicação entre os dispositivos de hardware existentes, efetivou-se a comunicação da plataforma autônoma e do microcomputador na estação terrestre através de um enlace de rádio freqüência, desenvolveu-se um programa visual que permite o acompanhamento do estado dos sensores/atuadores do sistema em terra em tempo mínimo e habilita para o usuário um controle remoto de navegação da embarcação autônoma de forma manual e completa se ocorrer a falha de algum equipamento de posicionamento. O programa armazena todas as variáveis referentes ao processo de coleta em um banco de dados, permitindo a análise e comparação das diferentes medições realizadas em diferentes períodos.
The data acquisition of the water chemical and physical variables in lakes and reservoirs is of extreme importance. Monitoring the quality of water supplied and consumed in our cities we are protecting the most valuable of our natural resources, and consequently our own lifes. Monitoring data quality, still in our days, is done in a conventional and hard manner. This work presents the development of a data and video telemetry system between an autonomous platform for water monitoring and a ground base. This system will complement the following already developed projects in this area, the autonomous platform constructed from a conventional boat with its engines, sensors and actuators; the data collecting probe, responsible for the acquisition of the water chemical and physical variables; the positioning system based on GPS and an electronic compass, responsible for navigation to the data collecting points in the reservoir. Communication algorithms between all the hardware were developed, radio frequency links were used to transmit data between the ground and the autonomous platform. A visual software application, that allows to visualize the state off the system variables, was developed. A remote control mode of the platform allows full manual navigation control of the platform, being of extreme importance in case of system crash. The visual software application developed allows to store all the important research variables in a data bank, allowing further analysis of the collected data.

Resumo: Nos últimos anos tem-se observado um crescente interesse de empresas e instituições de pesquisa pelo desenvolvimento de veículos robóticos, dotados de diferentes níveis de capacidade de operação autônoma, objetivando a execução de diversas tarefas. Dentro deste contexto o CenPRA, Centro de Pesquisas Renato Archer, propôs o Projeto AURORA. O Projeto AURORA (Autonomous Unmanned Remote mOnitoring Robotic Airship) tem como seu principal objetivo o desenvolvimento de protótipos de veículos aéreos tele-operados, e a obtenção de veículos telemonitorados, através do desenvolvimento de sistemas com graus de autonomia crescentes. Para que se possam agregar níveis crescentes de autonomia ao veículo, é essencial incrementar seu sistema de controle e navegação de maneira gradativa. Por esse motivo o aprimoramento das estratégias de controle do sistema é essencial. Assim, é primordial possuir um modelo fidedigno do sistema físico em questão, pois somente dessa forma é possível elaborar leis de controle e testá-las imediatamente em simulação antes de partir para os ensaios práticos no veículo real. Além disso, um modelo adequado é essencial para a simulação do vôo do dirigível de forma a permitir a análise preliminar de seu comportamento diante de uma nova missão. O principal objetivo deste trabalho é a implementação e validação de metodologias para a identificação do modelo dinâmico longitudinal do dirigível. Foram abordadas três metodologias para a identificação do modelo dinâmico do dirigível: a identificação estacionária, que identifica os coeficientes aerodinâmicos do dirigível a partir de um vôo estacionário, a identificação dinâmica, que identifica esses coeficientes e a dinâmica linearizada do veículo a partir de um vôo com entradas de perturbação conhecidas e, finalmente, a identificação por meio de estratégias evolutivas, que procura otimizar alguns parâmetros do modelo dinâmico. As três metodologias foram testadas, validadas e comparadas através de ensaios de simulação, utilizando-se o simulador do dirigível AS800 do Projeto AURORA

Project AURORA (Autonomous Unmanned Remote Monitoring Robotic Airship) aims at the development of unmanned airships remotely operated with a view to the creation of an autonomous flight airship by the incorporation of increasing levels of autonomy. In order to increase the vehicle autonomy level, the development of a proportionally enhanced control and navigation systems is essential. It is extremely important to have a very accurate model of the physical airship system, given that this is the only way to design control laws for the vehicle and test them in simulation before performing actual flight tests. Moreover, an accurate model is essential to predict the vehicle behavior in simulation before any real flight demanding a new type of mission. The definition of identification methodologies for the AS800 airship system identification is the main scope of this work. Three methodologies were considered to allow the airship dynamic model identification: stationary identification, which identifies aerodynamic coefficients from stationary stabilized flight conditions; dynamic identification, which identifies these coefficients and the vehicle linear dynamics from the application of known inputs into the system; and, finally, through evolution strategies, which uses an evolutionary approach for the optimization of the aerodynamic coefficients of the dynamic model. All the methodologies were tested, validated and compared through simulation experiments by using the AS800 airship simulator of the Project AURORA
