With the development of high-resolution satellite in earth observing technology, more and more data are transported from space to ground. In some cases, the space to ground communication link cannot afford so much data. Then, it's necessary to make efficient compression on the raw satellite data, which can reduce the bandwidths taken up by transmission, save the storage and shorten the transmission time. Based on this demand, the CCSDS recommended the standard of lossless data compression. Because the CCSDS recommendation is easy for implementation, more and more space systems begin to adapt this recommendation.
