Full textAbstract:
International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>Rapid technology growth in the aerospace industry continues to manifest in increasingly complex weapons systems and system driven weapons systems platforms which must be supported in the flight test environment. This growth in complexity often surpasses the capabilities of many ground based real-time and post-flight processing and display systems, leaving these systems perpetually behind the power curve when compared to data/information processing, presentation and distribution requirements set forth by today’s flight test engineering community. Many flight test programs are accepting less than optimal results from these systems, therefore, the amount of information presently obtained (per flight hour) limits the results acquired during a test program, creating a more costly test and evaluation budget. As an integral participant in the development and testing of high technology aircraft and weapons systems, the U.S. Air Force Flight Test Center’s (AFFTC) Advanced Data Acquisition and Processing Systems (ADAPS) development is bridging the gap between requirements and capability by distributing current system architectures to provide incremental performance upgrades in specific areas of need in lieu of entire system replacements. This paper will discuss the current real-time processing, distribution and display capability that exists at the AFFTC and the planned phased upgrade of this tightly coupled system to a more flexible and extensible distributed architecture that will be increasingly responsive to the dynamic nature of test and evaluation of modern weapons systems and weapons systems platforms.

The network-centric architecture is Windows NT-based, client/server based, supporting clients and servers on both local or remote PC workstations. The architecture supports distributing processing loads across multiple workstations, optimizing mission processing requirements. The advantage of this system is its flexibility and expandability with low acquisition and life-cycle support costs. The ATPDS allows the user to configure one or more small systems into a larger high-end system based on varying mission requirements.

Northern Arizona University (NAU) students are researching a new approach to apply virtual reality (VR) to evaluate data from a collection of stored signals. Each signal will have limits attached which we will use to view the parts of the waveform which contain abnormalities. A program to illustrate the technique is being developed by NAU students. Initially, we were working with Vizard 5, using the Python language. However, there is another program, Unity, which will perhaps be more useful for the application we wish to achieve. Additionally, we are examining a technique to accurately access the telemetry data collected. The amount of telemetry data collected has increased over the years resulting in difficulties in identifying the relevant information. We are searching for a better approach to store and access big data and will demonstrate this approach by utilizing Oculus Rift and Microsoft Kinect.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada<br>The growing complexity of missle, aircraft, and space vehicle systems, along with the advent of fly-by-wire and ultra-high performance unstable airframe technology has created an exploding demand for real time processing power. Recent VLSI developements have allowed addressing these needs in the design of a multi-processor subsystem supplying 10 MIPS and 5 MFLOPS per processor. To provide up to 70 MIPS a Digital Signal Processing subsystem may be configured with up to 7 Processors. Multiple subsystems may be employed in a data processing system to give the user virtually unlimited processing power. Within the DSP module, communication between cards is over a high speed, arbitrated Private Data bus. This prevents the saturation of the system bus with intermediate results, and allows a multiple processor configuration to make full use of each processor. Design goals for a single processor included executing number system conversions, data compression algorithms and 1st order polynomials in under 2 microseconds, and 5th order polynomials in under 4 microseconds. The processor design meets or exceeds all of these goals. Recently upgraded VLSI is available, and makes possible a performance enhancement to 11 MIPS and 9 MFLOPS per processor with reduced power consumption. Design tradeoffs and example applications are presented.

International Telemetering Conference Proceedings / October 26-29, 1987 / Town and Country Hotel, San Diego, California<br>An architecture is described for Processing Multiple digital PCM telemetry streams. This architecture is implemented using a collection of Motorola mono-board microprocessor units (MPUs) in a single chassis called an Intermediate Processing Unit (IPU). Multiple IPUs can be integrated using a common input data bus. Each IPU is capable of processing a single PCM digital telemetry stream. Processing, in this context, includes conversion of raw sample count data to engineering units; computation of derived quantities from measurement sample data; calculation of minimum, maximum, average and cyclic [(maximum - minimum)/2] values for both measurement and derived data over a preselected time interval; out-of-limit, dropout and wildpoint detection; strip chart recording of selected data; transmission of both measurement and derived data to a high-speed, large-capacity disk storage subsystem; and transmission of compressed data to the host computer for realtime processing and display. All processing is done in realtime with at most two PCM major frames time latency.

Included for consideration in the integrated processing are data acquisition, measurement displays, recording, derived measurement computations using both types of data, and post flight merging of telemetry and TSPI data. Data processing is discussed in a concurrent, multiple operation environment using separate, integrated processors.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California<br>Prior to 1985 the National Range had, for a number of years, serious and recurring mission support problems with the IBM 360 Telemetry Data Processing System due to equipment reliability and obsolescence of the system which was installed in 1968. These problems became particularly acute when higher data rate requirements and the need for reliable telemetry data processing dictated that prompt and unusual action was necessary if WSMR was to continue to provide telemetry data processing support. Realizing that the above cited problems of reliability and obsolescence would continue in detriment to the mission of WSMR, Department of Defense (DOD) and the nation, coupled with the loss of thousands of dollars in reimbursables due to WSMR's inability to support missile test requirements, the Systems Engineering Branch was tasked by the Director of National Range to lead a study, and propose and implement solutions to meet current and future requirements in telemetry data processing support. With the explosion in PCM data rates, it had become obvious that WSMR could not continue to upgrade existing systems and meet the demands of the future. More data parameters at higher data rates were being processed in PCM, FM, and PAM. Telemetry formats were becoming more complicated, such as embedded asynchronous subcomms and dynamic format changes. More real-time decisions had to be made for mission safety, verification of location, and mission success. WSMR needed a more versatile system that would synchronize, process and display higher data rates with more accuracy than it had at this time. This paper describes a historical perspective of steps WSMR has taken to satisfy present and future test vehicle telemetry data processing requirements.

Full textAbstract:
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California<br>As modern weapons grow more sophisticated and capable of operating autonomously, the challenge of testing these weapons has also grown more complex. Seekers may be multispectral and must be able to overcome threat countermeasures. To effectively analyze the performance of these weapons, time-correlated test data must be efficiently, simultaneously acquired from both the weapons' internal busses and from the threat countermeasures' internal communication busses, often in a "live fire" environment. The test data must be transmitted to a central processing station where test personnel may immediately analyze the performance of the weapon with the assistance of scientific visualization techniques. In addition, the data must be captured on permanent media for future playback and more detailed analysis. One solution is to link the test article, threat countermeasures and other test support resources through an Integrated Telemetry System (ITS). Instrumentation to acquire high-speed test data is installed in data collection vans that are remotely located in the vicinity of the article under test or in the vicinity of the threat countermeasures systems or test support resources. The remote vans will be interconnected and linked to a control van which provides a centralized test control and monitoring point. Remote Data Formatter (RDF) instrumentation units, located in the remote vans, can acquire data from and control seekers, sensors, emission sources or other equipment located in or near the remote vans. The RDF units can also format the data for transmission to the control van via either fiber optic or microwave radio links. The data transmitted from multiple remote vans is received by Real-time Data Processing System (RTPS) units located in the control van for merging, processing and recording. Some of the processed data can be transferred to a Host Processing System (HPS) where it can be displayed on color graphic workstations. The control van's HPS workstations provide user-friendly displays and menus for test setup and control. Both the remote and control vans are equipped with secure digital communication systems capable of supporting compressed digital video, audio, high-speed instrumentation data and an Ethernet computer network.

Full textAbstract:
Telemetry data has great value, as setting up a framework to collect and gather it involve significant costs. Further, the data itself has product diagnostic significance and may also have strategic national security importance if the product is defense or intelligence related. This potentially makes telemetry data a target for acquisition by hostile third parties. To mitigate this threat, data security principles should be employed by the organization to protect telemetry data. Data security is in an important element of a layered security strategy for the enterprise. The value proposition centers on the argument that if organization perimeter/internal defenses (e.g. firewall, IDS, etc.) fail enabling hostile entities to be able to access data found on internal company networks; they will be unable to read the data because it will be encrypted.
After reviewing important encryption background including accepted practices, standards, and architectural considerations regarding disk, file, database and application data protection encryption strategies; specific data security options applicable to telemetry post processing environments will be discussed providing tangible approaches to better protect organization telemetry data.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>There have been many recent technological advances in small computers, graphics stations, and system networks. This has made it possible to build highly advanced distributed processing systems for telemetry data acquisition and processing. Presently there is a plethora of vendors marketing powerful new network workstation hardware and software products. Computer vendors are rapidly developing new products as new technology continues to emerge. It is becoming difficult to procure and install a new computer system before it has been made obsolete by a competitor or even the same vendor. If one purchases the best hardware and software products individually, the system can end up being composed of incompatible components from different vendors that do not operate as one integrated homogeneous system. If one uses only hardware and software from one vendor in order to simplify system integration, the system will be limited to only those products that the vendor chooses to develop.
To truly take advantage of the rapidly advancing computer technology, today’s telemetry systems should be designed for an open systems environment. This paper defines an optimum open architecture system designed around industry wide standards for both hardware and software. This will allow for different vendor’s computers to operate in the same distributed networked system, and will allow software to be portable to the various computers and workstations in the system while maintaining the same user interface. The open architecture system allows for new products to be added as they become available to increase system performance and capability in a truly heterogeneous system environment.

The adoption of various standards, such as those recommended by the Consultative Committee for Space Data Systems (CCSDS), brings commonality of requirements across future NASA communications elements and affords the opportunity to create standard components to meet these requirements.
Over the past five years, NASA’s Goddard Space Flight Center (GSFC) has developed a series of high performance Very Large Scale Integration (VLSI) components for space data systems. These standard components have enabled the development of high performance data systems that are an order of magnitude more compact and cost effective than systems of the previous generation. Recent advances in design automation tools and integrated circuit densities have yielded the means to achieve yet another leap in the integration levels, performance and cost reduction of space data systems. Design automation tools can generate complex integrated circuit designs from high level technology independent functional descriptions. A single reusable functional description can be targeted to a variety of circuit technologies including CMOS, ECL and GaAs. With available densities of over 1 million integrated transistors in both CMOS and GaAs technologies, standard components integrating multiple processing elements are realizable for both flight and ground projects.
This paper describes the ongoing efforts of the Microelectronics Systems Branch at GSFC to create highly integrated components to meet functions outlined by the CCSDS using design automation techniques.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>Visions of future airborne data acquisition systems include the “network in the sky”
concept where a test or training participant logs on to the range network, just like today's
computer users on the ground log onto the local area network (LAN). Through two-way
telemetry links, the test or training participant seamlessly becomes a node in the range
network. Thus, easily sharing data with event controllers and other airborne, ship-,
ground-, and space-based network nodes. Such a network would allow the conduct of
highly integrated test/training scenarios involving virtual and real participants without
requiring physical proximity. This technology has a high payoff for the warfighter,
making it a desirable objective of present and future DoD-funded development of data
acquisition systems.
This much-anticipated, future state-of-the-art in data acquisition will require extensive
changes from today's test/training instrumentation architecture. Based on technology that
is currently emerging for computer networks, this paper describes an evolutionary path
for data acquisition systems to follow in order to achieve the anticipated bandwidth
required for future bandwidth-intensive applications like the network in the sky. New
networking paradigms, like Sun's Jini™ project, point the way to impressive usability
with dramatically lower costs and network administration in the near term for ground-based
networks, but they require support for just-in-time delivery of software “drivers”
and other applications. These need gigabit network speeds to be viable. If this and other
new networking technology is to be transferred to the test/training domain, bit rates will

This will potentially impact telemetry post processing in a myriad of ways. After reviewing how data security tools like Enterprise Rights Management (ERM), Enterprise Key Management (EKM), Data Loss Prevention (DLP), Database Activity Monitoring (DAM), and tokenization are impacting cloud security, their effect on telemetry post-processing will also be examined. An architecture will be described detailing how these data security tools can be utilized to make telemetry post-processing environments in the cloud more robust.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California<br>This paper discusses the telemetry processing and data verification performed by the SBV
Processing, Operations and Control Center (SPOCC) located at MIT Lincoln Laboratory
(MIT LL). The SPOCC is unique among the Midcourse Space Experiment (MSX) Data
Processing Centers because it supports operational demonstrations of the SBV sensor for
Space-Based Space Surveillance applications. The surveillance experiment objectives
focus on tracking of resident space objects (RSOs), including acquisition of newly
launched satellites. Since Space Surveillance operations have fundamentally short
timelines, the SPOCC must be deeply involved in the mission planning for the series of
observations and must receive and process the resulting data quickly. In order to achieve
these objectives, the MSX Concept of Operations (CONOPS) has been developed to
include the SPOCC in the operations planning process. The SPOCC is responsible for
generating all MSX spacecraft command information required to execute space
surveillance events using the MSX. This operating agreement and a highly automated
planning system at the SPOCC allow the planning timeline objectives to be met. In
addition, the Space Surveillance experiment scenarios call for active use of the 1 Mbps
real-time link to transmit processed targets tracks from the SBV to the SPOCC for
processing and for short time-line response of the SPOCC to process the track of the new
object and produce new commands for the MSX spacecraft, or other space surveillance
sensors, to re-acquire the object. To accomplish this, surveillance data processed and
stored onboard the SBV is transmitted to the APL Mission Processing Center via 1 Mbps
contacts with the dedicated Applied Physics Laboratory (APL) station, or via one of the
AFSCN RTS locations, which forwards the telemetry in real-time to APL. The Mission
Processing facility at APL automatically processes the MSX telemetry to extract the SBV
allocation and forwards the data via file transfer over a dedicated fractional T1 link to the
SPOCC. The data arriving at the SPOCC is automatically identified and processed to yield
calibrated metric observations of RSOs. These results are then fed forward into the
mission planning process for follow-up observations. In addition to the experiment support discussed above, the SPOCC monitors and stores
SBV housekeeping data, monitors payload health and status, and supports diagnosis and
correction. There are also software tools which support the assessment of the results of
surveillance experiments and to produce a number of products used by the SBV instrument
team to assess the overall performance characteristics of the SBV instrument.

As we all known, two aspects decide how fast the PC-based data acquisition can be reached. One aspect is CPU processing and the other is I/O bandwidth. Indeed, the first aspect has changed increasingly insignificant because the frequency of CPU has exceeded 700MHz which can satisfy fully the need of high rate data processing. So I/O bandwidth is the only key factor of the high rate PC-based data acquisition and we must adopt efficient data buffer techniques to satisfy the demand of telemetry data entry. This paper presents a buffered data channel which use memory mapping, EPLD and Dual-Port SRAM techniques. The operation platform of this design is WINDOWS95/98 and the software includes device driver and real-time processing routines.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California<br>The parallel processing technology has been widely applied to many science and engineering technical fields, also to telemetry. In particular, telemetry develops towards the trend of large capacity, high rate, several data streams and programmable formats. This sets a still higher demand on processing for real-time multilexing telemetry data. On the basis of analyzing of the characteristics of telemetry data processing (TDP), the parallel processing conception and methods are adopted, countering multiiple-channel data streams of different objects, several architectures of parallel processing for real-time multiplexing telemetry data are presented. It makes better use of the concurrency during the process of TDP and handles the telemetry information effectively in every processing level of the whole telemetering information processing system. The paper shows the property comparison of these parallel processing architectures and main features too. Experiments have indicated that it is an economical and effective method to improve the performance of telemetry information processing system by using paralle processing architecture which is based on concurrency of telemetry data processing.

Many flight test programs, and their respective test facilities, are looking to leverage their computing assets across multiple customers and programs. Typically, these complex programs require the ability to handle video, packet, and avionics bus data in real time, in addition to handling the more traditional PCM format. Current and future telemetry processing systems must have an architecture that will support the acquisition and processing of these varied data streams. This paper describes various architectural designs of both staged data flow and stream computing architectures, including current and future implementations. Processor types, bus design, and the effects of varying data types, including PCM, video, and packet telemetry, will be discussed.

hour or less. However, the digitized data produced by today's telemetry systems is
usually not in a format that can be directly analyzed by the test engineer's analysis
tools. The digitized data must be formatted before analysis can begin. The data
formatting process can take from one to eight hours depending on the amount of data,
the power of the system's host computer, and the complexity of the analysis software's
data format. If more than one analysis package is used by the test engineer, the data
has to be formatted separately for each package.
Using today's high-speed RISC processors and large memory technology, a real-time
Flexible Data Formatter can be added to the Telemetry Front End to perform this
formatting function. The Flexible Data Formatter (FDF) allows the telemetry user to
program the front-end hardware to output the telemetry test data in a format
compatible with the user's analysis software. The FDF can also output multiple data
files, each in a different format for supporting multiple analysis packages. This
eliminates the file formatting step, thus reducing the time to process the data from
each test by a factor of two to nine.

information comes to the central telemetry receiving/processing system from multiple

handling this ever increasing amount of information becomes more and more critical. In
response to this need, the Telemetry Definition and Processing (TDAP) system has been
developed by the Air Force Development Test Center (AFDTC) Eglin AFB, Florida.
TDAP standardizes the format of information required to convert PCM data and MIL-STD-1553 Bus data into engineering units. This includes both the format of the data files
and the software necessary to display, output, and extract subsets of data. These
standardized files are electronically available for TDAP users to review/update and are
then used to automatically set up telemetry acquisition systems. This paper describes how
TDAP is used to standardize the development and operational test community’s telemetry
data reduction process, both real-time and post-test.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>The performance testing of underseas weapons involves many of the same challenges as for other “smart” systems. Data sets on the order of GigaBytes must be extracted, processed, analyzed, and stored. A few KiloBytes of significant information must be efficiently identified and accessed for analysis out of the great mass of data. Data from various sources must be time correlated and fused together to allow full analysis of the complex interactions which lead to a given test result. The fact that the various sources all use different formats and medias just adds to the fun.
Testing of underseas weapons also involves some unique problems. Since real time data transmission is not practical; the vast bulk of the test data is recorded and then recovered with the vehicle at the end of the test. Acoustics are relied on for identification and ranging.
As systems continue to get smarter; the rates, capacities, and “smarts” of the equipment and software used to process test data must similarly increase. The NUWES telemetry capabilities developed to test and analyze underseas weapons could be of use on other government related projects.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California<br>The Information Processing Division (IPD) at the Goddard Space Flight Center (GSFC) has the primary responsibility for the data capture, short-term storage, quality assurance and accounting, pre-processing, and distribution of telemetry data from numerous National Aeronautics and Space Administration (NASA) spacecraft missions. This functional service is referred to as level 0 processing. Level 0 processing is differentiated from higher level processing in that the functions performed do not change the raw sensor or supporting data received and extracted from the telemetry streams (1). Error correction processing and the filling of data gaps to maintain continuity are included functions where applicable. Currently there are two basic forms of telemetry utilized by spacecraft missions supported by level 0 processing systems in the IPD; time division multiplexed and packetized. The basic processing services provided by these systems which are very similar have evolved over many years through experience with numerous spacecraft missions and differing user requirements. The goal of reducing the end-to-end information data system complexity and developmental and operational costs has led to the current extensive effort to standardize data formats utilized by spacecraft missions as well as the user services provided. It has been shown that the use of packetized telemetry will significantly reduce costs while enhancing service for future missions. Packet telemetry standards consistent with the international Consultative Committee for Space Data Standards (CCSDS) are being developed which will provide the basis for future mission data system implementations (2). The IPD has developed two facilities which provide level 0 processing for missions utilizing packetization; the Hubble Space Telescope (HST) Data Capture Facility (DCF) and the Packet Processor (Pacor). The HST DCF, a dedicated system, was the first to be developed and provided the basis for the development of the multimission Pacor DCF. The Pacor is currently capable of providing the processing for the Gamma Ray Observatory and other missions using non-standard packet formats and future missions using standard packet formats compatible with the CCSDS recommendations. Through the development of the packet processing systems, which included extensive working with users, standard level 0 processing functions and services evolved. It is felt that these functions and services form the basis for future implementations including those for the Space Station Freedom. This paper will detail these functions and services.

In the past, selected data was extracted and included in a standard PCM telemetry stream. But only the selected data was made available. In EA6B and in the proposed IRIG Standard, multiple Mil-Std-1553B data busses are combined with identifying control bits in a single PCM telemetry stream. All of the information traveling each bus is available to the ground station. These formats share a number of features. One is that for each Bus the Mil-Std-1553B word appears in the same order in the telemetry stream. Another is that individual data words do not depend on their position in the telemetry stream for identification, but they do depend on the control information associated with the current message to give meaning to the data words. An efficient approach is outlined for identifying, selecting and routing individual measurements, messages, and/or all Mil-Std-1553B bus information to processes and I/O devices in a data flow environment.
