Abstract: Lossless data compression is one of the major services in space flight missions and remote-sensing systems.Based on the preliminary study of CCSDS (Consultative Committee for Space Data System) recommended standard for lossless data compression,the fundamental principles and coding methods for the Rice algorithm recommended by CCSDS were discussed.Then its DSP (Digital Signal Processor) implementation and optimization version were addressed with the input data rate 11Mbit/s.The results in terms of performances show that it can be integrated into on-board data processing module for missions that don't require high throughout rate.Finally,how the lossless data compression was integrated into the CCSDS-based on-board data systems was studied.
