这是从IGS上下的精密卫星钟差信息 间隔为30秒的钟差信息 希望对相关人员有所帮助

本程序能解求卫星位置，钟差，地面点位置，钟差，是gps定位算法重要程序-This procedure can SOLUTIONS satellite position, clock bias, the ground position, clock error, an important process when the gps location algorithm

根据广播的卫星星历结算卫星的瞬时位置,卫星坐标，包括了 卫星钟差校正，全局延迟-According to the instantaneous position of the satellite broadcast satellite ephemeris settlement

提取GPS接收机报文中的数据，针对log指令“SATXYZ”，提取报文中GPS卫星的id ,GPS时间，3D坐标，钟差-Extract the data in the GPS receiver message, and extract the id, GPS time, 3D coordinates and clock difference of the GPS satellite in the message for the log instruction SATXYZ
