International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Alliant Techsystems’ Advanced Technology Applications organization incorporates the latest IRIG standards for range equipment and operation. Over the past five years, our objective has been to assure interoperability among diverse data recording users while achieving technical excellence for our ADARIO(Analog Digital Adaptable Input Output) family of products. In this paper, we summarize 25 years of ADARIO development; technical challenges, risks and processes; as well as our five-year effort to modify and develop our recording system products to meet the evolutionary standards of technical excellence.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The most recent version of IRIG 118, Test Methods for Telemetry Systems and Subsystems, was released in 1999 and does not include any guidance for testing IRIG 106 Chapter 10 recorder / reproducers. This paper will describe the methodology and tools used to perform a thorough testing process to ensure compliance with the IRIG 106-07 standard.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / IRIG-106 Chapter 10 has become the recording standard for most of the new flight test programs and many of the current ongoing programs. The primary goal of the standard was to define a common format for recording 100% bulk data such as PCM, MIL-STD-1553 busses, Video/Audio, ARINC-429, Ethernet, IEEE-1394, Analog Data, and others. In most cases the standard has provided the instrumentation engineers and the data analysts with a recording solution that meets their needs. Many programs require transmission of safety of flight data from a subset of the data acquired by the recorder. This may include selected video/audio channels, selected avionics bus data, and others. This requirement presents a dilemma to the flight test engineer who must duplicate part of the system for telemetry. This paper discusses several applications in which the IRIG-106 Chapter 10 recorder can be used as a telemetry system. It will include the transmission of bulk MIL-STD-1553 data per IRIG-106 Chapter 8, transmission of multiple Video/Audio and PCM data channels, and transmission of selected avionics data per IRIG-106 Chapter 4.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Range Commanders Council (RCC) Inter-Range Instrumentation Group (IRIG) 106 Chapter 10 (CH 10) Solid State recording standard has made the possibility of large scale interoperability between ranges, test and operational communities, and maintenance a reality. The standard allows for software and hardware playback/analysis tools to be created that will work seamlessly with any IRIG-106 CH 10 compliant recorder. Incorporation of a standard also allows the same recorder to record Video, Audio as well as data from MIL-STD-1553 busses and instrumentation data (PCM, UART, etc.). The IRIG-106 CH 10 standard provides enormous benefits for its users, but without a fully compliant IRIG-106 CH 10 recorder, these benefits cannot be realized.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The F-22 flight test program used a traditional distributed data acquisition system and a non IRIG-106 Chapter 10 recording system for its flight test program. In addition, it required a separate and very large Harris DAU system to monitor and record avionic data buses carrying secure data. Due to the size, cost, and the obsolescence of the Harris DAU system and components, Lockheed evaluated replacement systems. TTC proposed to develop F-22 specific Fiber Optic avionics bus monitors and an avionics PCM Data Selector / Encoder as part of its distributed IRIG-106 Chapter 10 Multiplexer / Recorder system to replace the Harris DAU. This replacement system challenges the traditional system approach used in many flight test programs. This paper describes the evolutionary process to design two independent distributed data acquisition and recording systems handling data with different classification levels. The data separation is maintained by way of system wiring, proper hardware that holds no residual data once power is removed, different transmission channels, hardware-based message blocking, and a separate IRIG-106 Chapter 10 multiplexing / recording system.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The RCC TTG initiated task TT-49 to generate a standard for the transport of serial streaming telemetry (TM) over the Internet Protocol (IP). An ad hoc committee was activated comprised of Range and vendor participation to develop this standard. This paper will address the progress of the standard, the use of commercial standards, and the benefits to the ranges. The early meetings focused on developing the packet structure; the preliminary results will be presented along with the latest status on the RCC approval cycle.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the development of a PC based IRIG tone generator and flight termination transmitter. The tone generator and flight termination transmitter card are part of a flight line test set. The test set has several PC based cards which include an S-Band telemetry receiver, a bit synchronizer, a decommutator, an encryption support card and the flight termination transmitter card. The test set can perform a complete end to end test of a weapon’s flight termination system prior to loading on an aircraft.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Recent advancements in IRIG 106 Chapter 10 recording systems allow the recording of all on board 1553 bus and PCM traffic to a single media. These advancements have also brought about the issue of extracting data with different levels of classification that was written to single location. Carrying GPS “smart” weapons further complicates this issue since the recording of GPS keys adds another level of classification to the mix. The ability to separate and/or remove higher level data from a data product is now required. This paper describes the design of a hardware device that will filter specified data from IRIG 106 Chapter 10 recorder memory modules (RMMs) to prevent the storage device or computer from becoming classified at the level of the specified data.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Rapid access to ever-increasing amounts of test data is becoming a problem. The authors have developed a data-mining methodology solution approach to provide a solution to catalog test files, search metadata attributes to derive test data files of interest, and query test data measurements using a web-based engine to produce results in seconds. Generated graphs allow the user to visualize an overview of the entire test for a selected set of measurements, with areas highlighted where the query conditions were satisfied. The user can then zoom into areas of interest and export selected information.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Telemetry Group (TG) of the Range Commanders Council (RCC) developed the Chapter 10 addition to the IRIG 106 standard to “establish a common interface standard for the implementation of solid-state digital data acquisition and on-board recording systems” ([1]). This standard is intended to allow the development of a common set of data playback/reduction software, minimizing the need for a large number of unique programs to handle proprietary data structures. This paper analyzes the Chapter 10 standard from a data processing perspective, providing insight into the benefits and challenges developers will face when writing Chapter 10 software.
