利用Huffman算法对RINEX格式GPS观测文件进行压缩

THE COMPRESSION OF GPS DATA FILE IN RINEX FORMAT WITH HUFFMAN ALGORITHM

针对 RINEX格式的 GPS观测数据文件 ,实现了利用 Huffm an算法进行数据压缩的软件编制并进行了成功的试验 ,数据压缩的比率在 44 %～ 5 0 %之间 ,优于一般压缩工具如 Winzip。

This paper forcuses on the programming realization of the compression of GPS observation data file in RINEX format with Huffman algorithm. The result of the experiment is successful. The proportion of the compression is between 44 % and 55 % and is superior to some common tools such as Winzip and Compress.
