北斗星历解析及实时卫星位置解算实现

Realization of BDS Ephemeris Division and Real-Time Satellite Position Calculation

利用C语言编程进行北斗卫星星历数据的实时读取,更新结构体的卫星轨道参数,从而实现北斗卫星位置的解算,并与武汉大学数据中心提供的北斗精密星历作比较,对解算的卫星位置结果进行评估,最大误差不超过3.5米,满足实际应用需要。

Real-time reading of Beidou satellite ephemeris is realized in the paper,the satellite orbit structure parameters are updated by C language programming to calculate the Beidou satellite position.The calculation results were compared with the precise ephemeris provided by IGS data center of Wuhan University to evaluate the real-time satellite position results.The maximum error is no more than 3.5 meters,which meets the needs of practical application.
