本文对华迅G PS/BD双模接收机输出的原始二进制数据的格式进行了深入讨论,利用M atlab对其输出的二进制数据的解码并提取出观测值、星历等,该方法可以简捷快速的解码出所需要的观测信息。
T he research in decoding the raw binary data of navigation receiver has impor-tant significance for improving receiver positioning .In this paper ,the original binary format of Huaxun GPS/BD dual-mode receiver output were discussed ,a method of using matlab to decode its output binary data was presented ,in order to extract the observation value ,e-phemeris ,and other information which are required for GPS data processing .This method be able to decode the observational data concisely and rapidly .These information has the vital significance in research of navigation principle ,pseudo-range differential and carrier phase differential .
