Assembling a Bi-Directional TM System Using IRIG Compliant Sub-Systems

Abstract

Full-duplex instrumentation communication and data links to an airborne test article has always been desired capability of Test and Evaluation (T&E) community. Years back, the need was small, but as aircraft instrumentation has matured and more and more remotely controlled vehicles are entering development, the need has grown. The satellite domain has full duplex using High-level Data Link Control (aka, HDLC, or ISO/IEC 13239:2002), but this has not been adopted into the IRIG standards. Instead, IRIG-106 was expanded to include Chapter 7 which acts as a “suitable substitute” for HDLC. Between Chapter 7, and the miniaturization of transmitters and receivers, putting receiving stations on test articles is now attainable. This paper shows how using the IRIG standards supported by the vendors supporting the International Telemetry Conference can be assembled.
