A Survey of Modern Instrumentation in Aerospace TT&C Earth Terminals

Abstract

This paper will provide an overview of the instrumentation of aerospace telemetry/systems in mobile and stationary earth terminals, using integrated circuits and LSI technology, microprocessors, computer graphics and measurement system. This instrumentation includes not only circuits to handle TT&C data, but also to analyze display and control system performance from the RF portion including considerations of sensitivity and effective radiated power, to tracking measurements, baseband and data system performance; to man-machine interfaces. This paper will also discuss modern display systems and techniques and will introduce the advantages of the use of the IEEE standard 488-1978 and RS-232 interface buses for the control and monitoring of TT&C equipment, including data processing with particular application to survivable earth terminals.
