Research on Simulation Algorithm of Beidou B1C Signal

This article researches the simulation algorithm of the Beidou B1C signal and discusses the key technology of the Beidou B1C signal simulation, including satellite position trajectory simulation and doppler frequency shift simulation. The Beidou B1C signal adopts a new spread spectrum code sequence, changes the structure of navigation message and improves the calculation method of the satellite position. Aiming at the problem of large amount of calculation in the satellite position trajectory simulation, a cubic spline interpolation method is proposed for optimization. The simulation results show that the simulation algorithm can generate the correct Beidou B1C signal.
