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.
