Research and software implementation of CCSDS Lossless Data Compression Algorithm

In this paper, Rice Lossless Data Compression Algorithm recommended by CCSDS (Consultative Committee for Space Data Systems) is introduced. Then, a method of software implementation is introduced. Furthermore, to improve the speed of software implementation of decompression algorithm, an improvement is suggested. Finally, a test of the software implementation of decompression algorithm used in the LDCM (Landsat Data Continuity Mission) satellite ground system is finished.
