Decommutation of Mil-Std 1553B Data from EA6B or IRIG Telemetry FormatsDevlin, Steve 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / With the acceptance of Mil-Std-1553B by vehicle and weapons industries a wealth of new information is available for vehicle testing. 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.

AN ALTERNATIVE METHOD FOR ACQUIRING AVIONIC BUS DATA IN A CLASS I PCM TELEMETRY SYSTEMSalley, Thomas, Thorssell, Steven E. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / IRIG 106-86 Chapter 8 describes the standard for acquisition of MIL-STD-1553 traffic flow. All incoming words (command, status, or data) are transmitted and fill words are used to maintain continuous data output. If all incoming words are not needed, or if other data such as sampled analog data from transducers are also to be transmitted, then a different approach is warranted. Selected data from the avionics bus can be placed into predefined PCM words, eliminating the transmission of useless data, and optimizing the bandwidth available to a Class I telemetry system. The engineering considerations and constraints for avionics bus data acquisition and analysis will be explored in this paper.

FIREWIRE: THE NEW 1553?Blott, Michaela 10 1900 (has links)
International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / MIL-STD-1553 has served the flight community well. However, in recent years several new high-speed bus standards have emerged that outperform 1553 in various respects such as data throughput and increased address space. During this time, mission requirements - including video and audio - have become more data intensive. Although some of these busses were not initially designed for the avionics industry (such as Ethernet, FireWire, and FibreChannel), they are potentially of interest as high-speed commercial off-the-shelf (COTS) solutions for both set-up and data acquisition. These busses offer not only improved overall system performance, in terms of aggregate sampling rates, but also simplify existing data acquisition system architectures. They require fewer high-bandwidth links which can serve for both set-up and data. This paper examines some of these issues, focusing in particular on IEEE1394, better known as FireWire.

IRIG-106 CHAPTER 10 RECORDER WITH BUILT-IN DATA FILTERING MECHANISMBerdugo, Albert, Natale, Louis 10 1900 (has links)
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 / Sixteen years ago, RCC added Chapter 8 to the IRIG-106 standard for the acquisition of 100% MIL-STD-1553 data from up to eight buses for recording and/or transmission. In the past 5 years, the RCC recording committee added Chapter 10 to the IRIG-106 standard for acquisition of 100% data from PCM, MIL-STD-1553 busses, Video, ARINC-429, Ethernet, IEEE-1394, and others. IRIG-106 Chapter 10 recorder suppliers have further developed customer-specific interfaces to meet additional customer needs. These needs have included unique radar and avionic bus interfaces such as F-16 Fibre Channel, F-35 Fibre Channel, F-22 FOTR, and others. IRIG-106 Chapter 8 and Chapter 10 have provided major challenges to the user community when the acquired avionics bus data included data that must be filtered and never leave the test platform via TM or recording media. The preferred method of filtering data to ensure that it is never recorded or transmitted is to do so at the interface level with the avionic busses. This paper describes the data filtering used on the F-22 Program for the MIL-STD-1553 buses and the FOTR bus as part of the IRIG-106 Chapter 10 Multiplexer/Recorder System. This filtering method blocks selected data at the interface level prior to being transferred over the system bus to the media(s). Additionally, the paper describes the configuration method for defining the data to be blocked and the report generated in order to allow for a second party to verify proper programming of the system.

CONVERTING ASYNCHRONOUS DATA INTO A STANDARD IRIG TELEMETRY FORMATPeart, David E., Talbert, Jim 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In recent years we have seen an increase in the use of MIL-STD-1553 buses and other asynchronous data sources used in new missile and launcher designs. The application of multiplexed asynchronous buses in missiles and launchers is very common today. With increasing application of asynchronous data sources into very complex systems the need to acquire, analyze, and present one hundred percent of the bus traffic in real time or near real time has become especially important during testing and diagnostic operations. This paper discusses ways of converting asynchronous data, including MIL-STD-1553, into a telemetry format that is suitable for encryption, telemetering, recording, and presenting with Inter Range Instrumentation Group (IRIG) compatible off-the-shelf hardware. The importance of these designs is to provide the capability to conserve data bandwidth and to maximize the use of existing hardware. In addition, this paper will discuss a unique decode and time tagging design that conserves data storage when compared to the methods in IRIG Standard 106-96 and still maintains a very accurate time tag.

MIL-STD-1553 Data Acquisition SystemLandry, Michael 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / The Range Commanders Council recently added a chapter to IRIG 106-86 which describes a standard for acquisition of MIL-STD-1553 traffic flow. A system has been developed which monitors bus traffic using the format described in the standard for encoding. In addition to bus data, PCM analog channels can be inserted into the telemetry steam. Due to the high bandwidth of the telemetry stream, real-time ground processing of the 1553 data is difficult. Therefore, a limited number of selective measurements taken from the bus traffic are available at fixed positions in the telemetry format for real-time monitoring of critical parameters. A discussion of hardware, software, encoding, and testing will be presented.

Bulk Creation of Data Acquisition ParametersKupferschmidt, Benjamin 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / Modern data acquisition systems can be very time consuming to configure. The most time consuming aspect of configuring a data acquisition system is defining the measurements that the system will collect. Each measurement has to be uniquely identified in the system and the system needs to know what data the measurement will sample. Data acquisition systems are capable of sampling thousands of measurements in a single test flight. If all of the measurements are created by hand, it can take many hours to input all of the required measurements into the data acquisition system's setup software. This process can also be extremely tedious since many measurements are very similar. This paper will examine several possible solutions to the problem of rapidly creating large numbers of data acquisition measurements. If the list of measurements that need to be created already exists in an electronic format then the simplest approach would be to create an importer. The two main ways to import data are XML and comma separated value files. This paper will discuss the advantages and disadvantages of both approaches. In addition to importers, this paper will discuss a system that can be used to create large numbers of similar measurements very quickly. This system is ideally suited to MILSTD- 1553 and ARINC-429 bus data. It exploits the fact that most bus measurements are typically very similar to each other. For example, 1553 measurements typically differ only in terms of the command word and the selected data words. This system allows the user to specify ranges of data words for each command word. It can then create the measurements based on the user specified ranges.

AATIS AND CAIS DATA RECORDINGGaddis, William R. Jr, Sandland, Sawn 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / DOD flight test centers need affordable, small-format, flight-qualified digital
instrumentation recording solutions to support existing and future flight testing. The
Advanced Airborne Test Instrumentation System (AATIS) is today's primary data
acquisition system at the Air Force Flight Test Center (AFFTC). Digital Recorder
(DR) 1995 is planned to provide full support for AATIS output capabilities and satisfy
initial recording requirements for the Common Airborne Instrumentation System
(CAIS). The follow-on to the AATIS, the CAIS is a tri-service development to satisfy
future DOD flight test data acquisition requirements. DR 2000 is planned as the future
recording solution for CAIS and will be able to fully satisfy the 50 Mbps recording
requirement. In the developments of DR 1995 and DR 2000, commonality and
interoperability have emerged as significant issues. This paper presents an overview
of these recording solutions and examines commonality and interoperability issues.
