Advanced concepts for telemetry data systems

Abstract

The Consultative Committee for Space Data Standards (CCSDS) has defined Advanced Orbiting System (AOS) standards for the overall architectural framework of future packet telemetry systems. The standards encompass a CCSDS principal network covering the onboard space-link and ground systems, and furnishes an asynchronous (telemetry/internetworking) and isochronous (audio and video) data-transport services employing CCSDS packets and virtual channels. Attention is given to changes envisioned in ground telemetry processing systems currently in use, as well as to the application of CCSDS standards to future systems.
