MULTIPLEXER / DEMULTIPLEXER IMPLEMENTATION USING A CCSDS FORMATGrebe, David L.; Apogee Labs, Incorporated (International Foundation for Telemetering, 1997-10)A multiplexer / demultiplexer design suitable to a wide range of input data types and link formats is presented. Based on the Consultative Committee on Space Data Systems (CCSDS) recommendations for Packet Telemetry, the design translates the prescribed layered architecture into a modular, layered hardware implementation. The design approach minimizes hardware yielding increased reliability and decreased product cost while retaining a high degree of flexibility. This implementation can be applied to flight data acquisition (direct transmission to the ground or recorded), ground data collection (including multi-stream record systems) and inter-range communications. The use of an internationally recognized standard promotes inter-service interoperability and facilitates data handling/routing throughout a wide community.
