摘　　要：基于北斗卫星定位系统的定位原理,对北斗卫星观测数据的生成进行研究,在此基础上,设计和实现Beidou(BD)观测数据仿真系统,该系统可根据已知测站的三维位置恢复得出该测站可接收的卫星信号并计算出星站之间的距离,并且可以模拟如卫星钟差、电离层延迟、对流层延迟等各种系统误差。Based on Beidou satellite positioning system positioning principle, studies how to generate the Beidou satellite observation data. On this basis, designs and implements the simulation system of the Beidou observed data. The system can obtain the satellite signals received based on the three-dimensional position of the known station and compute the distance between the star and observed station. In addition,it can simulate many system errors, for example, the satellite clock error, the ionospheric delay, the tropospheric delay and so on.
