FIBRE CHANNEL BUS MONITORING WITH AIRBORNE DATA MULTIPLEXER / RECORDER SYSTEM

Berdugo, Albert, Pesciotta, Eric 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 / Modern aircraft now employ widely accepted and standardized technology commonly found in COTS applications. One such technology, Fibre Channel, has been deployed to transport both low and high-speed measurement data. Data as varied as “command and control”, “Radar Sensors” and “video” are being transmitted over fibre channel on many aircrafts. Some of these applications require data monitoring in listening mode only where transmission from the instrumentation equipment is not allowed or possible. As a result, standard off the shelf Fibre Channel devices cannot be used, and a development of a general purpose Fibre Channel monitor/ analyzer device and product is required. This paper discusses the concept, merits, and implementation of fibre channel bus monitoring in modern data acquisition systems. Techniques for tapping into an optical fibre channel network, as well as, a recording format for IRIG106 Chapter 10 are included. An overview of fibre channel topologies and protocols is also provided.

PCM Telemetry Downlink for IRIG 106 Chapter 10 Data

Pappas, Johnny, Bagó, Balázs, Cranley, Nikki, Poisson, Gabriel 10 1900 (has links)
ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / Since both airborne and ground applications are able to handle and process IRIG 106, Chapter 10 standard data (further referred to as C10) from files or from live streaming UDP network data, it is a logical extension of the standard to telemeter network data from the air to the ground support systems with little or no modification. This paper describes a method to transport C10 compliant packets over a Class II, telemetry stream (C10 TMDL) which is fully compatible with existing encryptors, transmitters, receivers, and decryptors.

IRIG 106 Chapter 10 vs. iNET Packetization: Data Storage and Retrieval

Jones, Charles H. 10 1900 (has links)
ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / The approach to recording data during Test & Evaluation has evolved dramatically over the decades. A simple, traditional approach is to pull all data into a PCM format and record that. A common current approach is to record data in an IRIG 106 Chapter 10 compliant format that records different forms of data (bus, discrete, video, etc.) in different channels of the recorder or exported data file. With network telemetry on the horizon, in the form of the integrated Network Enhanced Telemetry (iNET) standards, much of the data will be transported in iNET messages via Ethernet frames. These messages can potentially carry any type of data from any source. How do we record this data? Ultimately, no matter how the data is stored, it must be translated into a form that can be used for data analysis. Data storage forms that are conducive to this analysis are not necessarily the same that are conducive to real time recording. This paper discusses options and tradeoffs of different approaches to incorporating iNET data structures into the existing T&E architecture.

Conversion and Analysis of Telemetric Data from the CCSDS Standard

Ahlgren, Simon, Aini, Daniel January 2017 (has links)
When communicating with spacecrafts, the international standard is to use the protocols defined by CCSDS. In this study, the Space Packet Protocol from CCSDS is converted to the Digital Recording Standard used in aviation. The goal of the study is to find out in what way such a conversion can be made, as well as analyzing the efficiency of different packing methods for the Digital Recording Standard. An application is developed in order to perform the conversion, and the performance of said application is profiled using different packet sizes. In the end the results are evaluated and an optimal packet size is found in terms of runtime and memory usage. In the end we conclude that a packet size of 216 bytes is best when prioritizing speed, and a packet size of 219 bytes is best when prioritizing memory.

ENHANCING THE TELEMETRY ATTRIBUTES TRANSFER STANDARD (TMATS) TO INCLUDE INSTRUMENTATION DATA AND NEW DATA CONVERSION FORMATS

Lockard, Michael, Ziegler, Brian, Conway, Brian 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / As stated in IRIG 106-93/96/99/00, the purpose of the Telemetry Attributes Transfer Standard (TMATS) is; “... provides a common format for the transfer of information between the user and a test range or between ranges. This format will minimize the 'station unique' activities that are necessary to support any test item. In addition, it is intended to relieve the labor intensive process currently required to reformat the information by providing the information on computer compatible media, thus reducing errors and requiring less preparation time for test support.” However, it is well known that TMATS does not support “Instrumentation” data. Also, TMATS does not include many current data conversion formats, or have a way to easily include new formats as they are adopted. We believe that such changes will help TMATS reach its full potential and become more closely aligned with its stated objectives. It is the hope of the authors that this paper will generate support for IRIG to revise TMATS to include these important amendments.

A ROADMAP TO STANDARDIZING THE IRIG 106 CHAPTER 10 COMPLIANT DATA FILTERING AND OVERWRITNG SOFTWARE PROCESS

Berard, Alfredo, Manning, Dennis, Kim, Jeong Min 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 / High speed digital recorders have revolutionized the way Major Range and Test Facility Bases collect instrumentation data. One challenge facing these organizations is the need for a validated process for the separation of specific data channels and/or data from multiplexed recordings. Several organizations within Eglin Air Force Base have joined forces to establish the requirements and validate a software process compliant with the IRIG-106 Chapter 10 Digital Recording Standard (which defines allowable media access, data packetization, and error controls mechanics). This paper describes a roadmap to standardizing the process to produce this software process, Data Overwriting and Filtering Application (DOFA).

OVERVIEW OF AN INTEGRATED INSTRUMENTATION DATA SYSTEM USED BY THE F-35 LIGHTNING II FLIGHT TEST PROGRAM

Vu, Doug, Berdugo, Albert 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 / The Joint Strike Fighter program is the largest DOD contract ever awarded. There are three F-35 Lightning II variations, each intended to meet the specific needs of the Air Force, Navy, Marine Corps, and U.S. Allies. The Data System required for this flight test program challenged the conventional ways used in instrumenting test aircraft. Typical data systems available today don’t provide the level of hardware and software integration required for today’s complex applications. For example, cockpit control panels, recording systems, TM transmitters, data acquisition systems and avionic bus interface units are all independent systems. Additionally, avionic bus catalogs, ground-based systems, and flight setup software have historically been independent components. This paper will describe the hardware and software components used by the F-35 flight test program to provide an integrated system. A special emphasis will be given to the methods used to accommodate rapid changes to the IEEE-1394B avionic bus catalog including the acquisition of that data, and the use of an IRIG-106 Chapter 10 distributed multiplexer / recorder system, which is being used simultaneously as a data acquisition system.
