Architecture Design of Multisystem Satellite Navigation Signal Simulator Base on Software

Abstract:

Compared to conventional navigation signal simulators, software simulator has many advantages, which include flexible design, easy extending, strong openness, and low cost. With the development of satellite navigation, satellite navigation system is getting more and more complicated. Based on the analysis for satellite navigation signal model in different modulation methods of multisystem, it is very urgent to establish a unified description method, which can reduce duplication writing of algorithm. firstly, description method for multisystem satellite navigation signal simulator is proposed. Secondly, it can describe different systems of satellite navigation signals and provide estimation method for signal transmission delay time and Doppler frequency shift. Finally, the signal of simulation is validated.
