Microprocessors for Satellite Telemetry - A Universal Approach

Abstract

A system has been developed which can be flexibly tailored to meet most telemetry requirements. The concept results in higher reliability, greater modularity, and lower cost than classical approaches. It also offers more system capability. The development was realized by adaptation of the telemetry requirements to a computer system architecture. Such an adaptation is made possible by the use of a microprocessor as a device controller. The concept has been successfully applied to a specific telemetry requirement for use on a satellite. The results have far-reaching implications on the future of spacecraft electronics. Reductions in overall system hardware are possible while increasing the functional capability.
