EOSDIS TEST SYSTEM (ETS) HIGH-RATE SYSTEM (HRS)

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, NevadaNASA’s use of high bandwidth packetized Consultative Committee for Space Data Systems (CCSDS) telemetry in the Earth Observing System (EOS) mission presents a great challenge to ground data system developers. The EOS mission calls for high data rate interfaces and small packet sizes which would dramatically increase the real-time workload on ground packet processing systems. NASA’s Goddard Space Flight Center (GSFC) has been developing packet processing subsystems for over a decade. This paper will discuss the design of a high-rate telemetry test system and a simulation software package. The system will support CCSDS telemetry formats and perform frame synchronization, error detection and correction, packet reassembly and sorting, error checking, and data set creation. In addition, a highly automated operation environment is designed to minimize human intervention in control and monitoring, and data distribution. The design is based on a Very Large Scale Integration (VLSI) Level Zero Processing (LZP) System technologies, VLSI telemetry data simulation and processing functional components, Object-Oriented Design methodologies, C++ programming environment, shareware and Open Software Foundation (OSF)/Motif-based Graphical User Interfaces (GUI).International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
