A Versatile Aerospace Telemetry System

In general, the trend toward telemetry systems of increased flexibility and versatility for aerospace vehicles has yielded unacceptable power and processing efficiencies and questionable reliabilities. This paper describes the concepts, organization, and areas of application of a core-memory-programmed telemetry system which has been specifically developed, in its entirety, to provide the versatility required for aerospace vehicular applications and environments. It is felt that this versatility has been achieved, since the telemeter can reasonably be applied to dataprocessing requirements in such diverse areas as deep-space probes, orbiting spacecraft, or avionic data systems. Although format generation is its primary mode of operation, modular expansion of the basic system permits the expanded telemeter to perform as an integral datacompression system. The paper also describes the development of a laboratory model of this versatile telemetry system, which has been constructed to physically implement the various system functions described herein.
