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.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaThe Global Positioning System has achieved a maturity whereby a large marketplace of users have developed. This marketplace has been flooded with many types of receivers from a large number of manufacturers. The broad acceptance of the system among military as well as commercial users has created this market, and receiver availability due to planned mass production has precipitated substantial price reduction for GPS receivers. OEM receivers are presently available on the market at such a low cost that their incorporation into flight test systems should be seriously considered. The data produced by the system has a reasonable and usable accuracy for platform position, flight vectors and time. These are suitable in most range applications and can either augment or replace present tracking methods such as multilateration or triangulation for vehicle position. The advantages of eliminating the need for tracking functions in ground control stations are obvious especially in multi-vehicle operations such as in air-to-air weaponry testing and range training missions. The simplification of operation in position determination becomes especially desirable for over-the-horizon platforms. In this case, ground or airborne relays must be employed which complicates the location task by orders of magnitude.

Most test programs seem to have minimal problems with S-band telemetry interfering with GPS performance if a bandpass filter is used between the GPS antenna and the low noise amplifier (LNA). This paper will present measured data on GPS performance with L- and S-band telemetry and explain what must be done to minimize interference to GPS. The paper will present both GPS signal-to-noise ratio (S/N) values as well as measured spectra from telemetry transmitters. System design guidelines for compatible operation will be presented.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaThis paper outlines the GPS data acquisition of two PCM encoders. The design of the first PCM Encoder uses an embedded GPS Receiver module, the Thales G12- HDMA receiver. The G12 Receiver has been integrated into the electronics of the PCM Encoder to provide a seamless tool for the Telemetry Engineer to acquire GPS position and time data with the sensor data acquired from the PCM Encoder. The second telemetry encoder discussed in this paper adds the GPS Interface Module for the Time Space Position Unit (TSPI) currently under development at Herley Industries. The TSPI Unit will also be integrated with the PCM Encoder tools to create a seamless user interface. The TSPI unit is available in both the “Low Dynamic (JTU-I)” and the “High Dynamic” (JTU-II).

Currently many airborne platforms (missiles, targets, and projectiles) contain multiple instrumentation systems to cover the functions of GPS and either telemetry, beacon tracking and/or flight termination. Most of these platforms are not very large, so mounting of various antennas to support these functions are physically close to each other. As a result, unwanted interference (in the form of RF coupling between them) is unavoidable. This paper will discuss the design considerations involved to minimize this interference as well as some lessons learned with its implementation.

For the speed of target is very high, it is difficult for traditional positioning system to capture and track the target. TDOA (time difference of arrival) positioning system is used in reentry measurement. The position of target is calculated by using time difference of arrival. This paper introduces the principle of reentry TDOA positioning system. The key technology is synchronization of ground stations' clocks. The implementation of clock synchronization using low-cost commercial GPS receiver is presented. The sources of errors in the existing telemetry system, corresponding precision and experimental results are presented. Some methods, which are used to improve the precision, are proposed at the end of this paper.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe use of Global Positioning System (GPS) receivers as a source to provide Time Space and Position Information (TSPI), and Miss Distance Indication (MDI) data in Test and Evaluation (T&E) applications is being considered. Specifically, GPS receivers are being evaluated to determine their usefulness as a sensor in a Sidewinder missile telemetry system (AN/DKT-80). Initial testing has indicated that position information generated from a GPS receiver can provide significantly better position data than a radar tracking system when using Double Differential error correction techniques. This concept requires a GPS reference station to be located in the general proximity of the Telemetry data-receiving site. Software has been developed that will compare GPS data from the airborne telemetry system to the GPS reference station and display a real-time TSPI solution. This software will also provide MDI information from two different airborne sources that are equipped with GPS receivers (missile and drone). To prove out this concept, a Commercial Off the Shelf (COTS) Commercially/Available (C/A) code GPS receiver was integrated into the AN/DKT-80 Sidewinder telemetry system (TM). A MQM-107 drone was instrumented with the same GPS receiver, as was a ground based reference station. A simple TM was developed for the drone that telemeters only the GPS data. The modified AN/DKT-80 system incorporated an Inertial Measurement Unit (IMU) into the design. Post processing software was developed that will integrate the IMU information with the GPS data so accurate position can be generated if the GPS data was momentarily lost. A missile firing is scheduled for the spring of 1999 to prove this concept.

Abstract
GPS telemetry is a method with good accuracy to determine animal movements in the terrain. It is necessary to determine locations of free-ranging animals in order to understand movement patterns and habitat use, and to understand the consequences of human impacts like highways. This study aims to describe moose movement patterns and to evaluate the effect of highway traffic intensity on moose movements across a highway.
Moose in Southwestern Sweden have different movement rates throughout the year. Increased movement rate for females was observed during spring and summer. The breeding season (15 September -15 October) is the most important season for bulls. Our result shows that bulls significantly increase their movement rate during the rut, compared to other times during the fall. Movement rate increased twice compared with female movement rate during this period. No difference was observed during the rutting period for females (15 September- 15 October) compared with no rutting period during fall. During winter time, both sexes retain low movements, mainly caused by energy saving actions. A distinct crepuscular rhythm was exhibited during the summer and fall season, movements were more intense during dawn and dusk hours. No distinct crepuscular rhythm was noticed during winter and spring seasons.
The traffic intensity at highway E6 in Southwestern Sweden increases during the morning hours and reaches its maximum during midday. Moose in southwestern Sweden crossed highway E6 more often at night time than day time. Thus highway crossings by moose occurred at times of peak moose movements, and traffic volume had lower importance.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, NevadaAs testing requirements on the ranges require ever more sophisticated cross correlation of data from multiple data acquisition sources, it becomes increasingly advantageous to collect and disseminate this information in a more network oriented fashion. This allows any of the data collected at physically separated sites to be used simultaneously at multiple mission control or data reduction centers. This paper presents an approach that maximizes the use of legacy communication paths and data reduction systems to support an evolutionary migration toward the day when testing can take full advantage of commercial communication protocols and equipment such as OC-3, ATM, etc. One key element of this approach is the packetizing of data at each reception point to provide virtual circuit switching using packet routing. Based on the newly adopted IRIG/RCC 107-98 standard, the system may even be expanded all the way back to the actual sensors. The second key element is the use of the readily available time and timing pulses based on GPS to establish a uniform sampling interval that will allow the cross correlation of data received at different points spread over a wide area.

Limited data will be provided by Huygens as it descends to the surface via parachute and by Cassini as it orbits Saturn and occasionally passes near Titan. Interest in Titan is high because of its planet-class size, dense atmosphere, and the possibility of continents and seas. Already, there are discussions for a follow-on mission to Titan. There are several proposed designs such as balloons and boats to explore Titan's ethane seas. In all cases, reliable data links back to Earth are absolutely essential. However, simply increasing the power has its limits due to constraints on launch weights. There are a number of possible options for getting data back from Titan. These alternatives, and their effect on the mission profile are discussed.

Full textAbstract:
This master thesis is focused on GPS telemetry of red deer (Cervus elaphus) and sika deer (Cervus nippon) in the Doupov Mts., the Czech republic. Positional data from 14 red deer does and 2 sika deer does was collected during the study period of April 2013 to February 2016. The main aim was to determine habitat preferences of does with the use of the very precise vertical differentiation of vegetation created by air laser scanning of the surface (LiDAR technology). The study examines the dependence of the average maximum height of vegetation nearby positions of does on the time of year and time of day. For the evaluation was used two-way factorial analysis of variance. The highest average height of the vegetation nearby does was found during the day and the lowest during the night. Does of red deer and sika deer occurred in open habitats particularly at night, where they were actively seeking for food and more closed habitats with higher vegetation during the day, where they could hide themselves. Focusing on a period of the year, the height of vegetation in the summer period without hunting was significantly lower than in the summer period with hunting. This could be caused by starting hunting season but also it might be a response to reduced quality of available grass by aging. The two does of sika deer were treated individually. Significant differences were revealed between both does. However they both were occupying habitats with the lowest height of vegetation at night during the rut season.
The gained results can now be used to supplement information about ethology of red deer and sika deer. The comprehensive knowledge of ethology can be directly used in the management of these two species, particularly for hunting efficiency and subsequent reduction of their population numbers, particularly in the case of sika deer. However these results can be directly used in forest management in active protection of forest stands against damage by wild game.

Traditionally slip rings were used for data transfer however these result in issues with low bandwidth, electrical noise, installation complexity, and high maintenance costs. This paper describes a networked system using standardized technologies and protocols that was used for data acquisition and recording of parameters such as vibration, strain, and video on DAQ installed on the rotating part. The acquired data was transmitted in real-time via the network-centric wireless telemetry link which was synchronized with a ground-based DAQ used for real time processing of the rotor data.

Optimizing the antenna coverage and decreasing the noise figure are constantly strived for in order to improve system performance. At the same time, weapon systems are becoming smaller with the resulting reduced area for instrumentation. One way to achieve a lower system noise figure is to have the limiter, filter, and amplifier (LFA) located as close to the antenna as possible. This can be achieved by integrating the LFA into the substrate of a conformal wraparound antenna. Not only does this decrease the system noise, but it also saves space in an already crowded missile instrumentation section. This paper details the latest efforts in accomplishing this integration.

ProSEDS will demonstrate the use of an electrodynamic tether propulsion system and will utilize a conducting wire tether to generate limited spacecraft power. This paper will provide an overview of the ProSEDS mission and will discuss the design, and test of the spacecraft telemetry system. The ProSEDS telemetry subsystem employs a combination of Commercial Off-The-Shelf (COTS) hardware and launch vehicle telemetry system components to minimize costs as well as power consumption. Several measures were used to aid the conservation of spacecraft power resources. First, the transmitter was modified to limit input power consumption to less that 20 watts while providing approximately two watts Radio Frequency (RF) output power. Secondly, the ProSEDS on board Global Positioning System (GPS) receiver is being used to control input power to the transmitter in order to limit the telemetry operations to occasions when the spacecraft is in proximity to preprogrammed ground station locations.

region and seven of females were collared with GPS collars. These individuals were monitored for a year and their seasonal habitat selection and home range sizes are determined by using location data recorded on the collars. In addition to 4 seasons of the year, home range and habitat selection are estimated for mating and calving periods. Also, summer period is divided to two as summer1 and summer 2 because of changing availability of water resources in study area. Seasonal home range sizes of GPS collared gazelles are estimated as average 3.61 ±
0.47 km2 for winter, 3.96 ±
0.44 km2 for spring, 4.55 ±
1.35 km2 for summer1, 2.26 ±

0.50 km2 for mating season, and 1.66 ±
0.50 km2 for calving season.Seven habitat variable layers were prepared for the evaluation of seasonal habitat selection of GPS collared female gazelles. Gazelles were selected east aspects in summer and west aspects in winter seasons and, north and flat aspects were avoided in all seasons for a year. Water can be considered the key habitat variable for the goitered gazelles. The results show that some home ranges are outside of the protected area and gazelles do not use large areas in the protected area. In order to improve conservation of gazelles, protected area should be re-arranged and shifted to more intensely used areas by gazelles.

The second part of the thesis is focused on my own research.
The Positional data monitored hind Dorothy was collected in the period 1. 7. 30. 3. 2014. The aim was to determine, if the time hunting have to influence to microhabitat preferences on the hind of red deer and if the selection of posts are accidental or is influenced by the characteristics of the post. The Research conducted of data inventory from GPS using collar and of data, which arised laser air scanning the surface (technology LiDAR). For comparison and finding the preferences of the hind was created the network accidental comparative points. Field exploration and LiDAR technology consider the dependence of the average height of vegetation around of Dorothy positions the period of the year and the time of day. Data was evaluated ANOVA for the non-parametric data distribution (Kruskal-Wallisova) and the program Microsoft Excel. At each station has been carefully identified information about the location including visibility of the hunting-game device and height of stand.
The results indicate that the average height of the vegetation was at the stands searched by the hind of red deer during a sunrise and a day. The lowest was in night and at sunset. The hind of red deer prefer, in hunting time during the day, thick scrub and during the night more open spaces with larger views properties, where she actively looking for food. The most preferred visibility at the time of hunting and off time hunting was to the eastern direction. The most least preferred visibility was always to the western direction. Minimum presence of the hunting-game device is in the time of hunting during at the day and sunrise, maximum at night. This behavior was probably caused increased hunting activity.
The results of the thesis may be used in forestry management, for forest protection and by planning of hunting management of the red deer populations.

While there are no global oceans of liquid ethane/methane as once conjectured, the imagery does suggest the possibility of seas or lakes of liquid ethane, methane, and other organic materials. If these exist, Titan could be considered a gigantic analog model of the Earth's climate system complete with land masses, moderately thick atmosphere, and large bodies of liquid. By studying the climate of Titan, we could gain further understanding of the processes and mechanisms that shape the Earth's climate. Reuse of existing technology and methods may be a way to speed development and lower costs for the global study of Titan. Surprisingly, one of the key technologies could be a Transit or Global Positioning System (GPS) descendant for use in tracking probes wandering the surface of Titan.

The first series of vehicles will likely be reduced-scale models that restrict the locations and geometric shapes of the telemetry antennas. High kinetic heating will further limit antenna design and construction. Consequently, antennas radiation patterns will be sub-optimal, showing lower gains and detrimental nulls.

Many of these platforms also include Global Positioning System (GPS)-based Time-Space-Position-Information (TSPI) instrumentation systems. Due to space and other limitations, many of these platforms have demanding antenna placement limitations requiring closely spaced antennas. This paper describes steps taken to identify and mitigate potential interference to GPS-based TSPI instrumentation systems by these new technology transmitters. Equipment characterization was accomplished to determine interference potential of the proposed new transmitters and susceptibility of several GPS TSPI receivers. Several filtering techniques were identified as possible solutions to the anticipated interference problems. Telemetry (TM)/GPS system mockups and laboratory tests of the same were accomplished. Open-air testing was then accomplished to validate laboratory results. Finally, on aircraft tests were accomplished prior to performing any aircraft system modifications. Results of these test efforts are presented for others to consider when planning similar modifications to other platforms.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, CaliforniaOptical trackers are often used at the Air Force Flight Test Center (AFFTC) and at other Department of Defense (DoD) ranges to collect video and trajectory data for real-time display and postflight processing. When optical trackers are used in remote areas, pointing data from radar is utilized to enable the trackers to initially acquire targets. To enable the trackers to use radar-pointing data, offsets to true north must first be known. This offset is taken into account given the current position of the optical tracker. During postflight processing, when determining the trajectory of the target, the offsets are also taken into account to produce an accurate trajectory solution. Current methods of determining offsets to true north are time consuming and involve a lot of guesswork. Typically, a map and a known landmark are used to determine the offsets to true north. Another method is to look for the North Star (Polaris) and input an estimated offset. This paper will describe an inexpensive, stand-alone system that utilizes the Global Positioning System (GPS) to determine these offsets. This device may be modified and integrated with other systems that may need to point accurately. For example, a gun barrel on a tank may need to point accurately to within a degree. This device may also be used to accurately position telemetry antennas.
