Abstract

The pseudo-code ranging precision is an important indicator of satellite navigation system. The current channel modeling and simulation of BOC signal receiver is still no general method for quantitative analysis. Based on this situation, in this paper the model of channel estimation is proposed based on ranging precision of BOC receiver, then relationship between the channel characteristics and pseudo-code ranging accuracy is derived, and the influence brought by different bandwidth of front-end signal and channel characteristics on the ranging accuracy is analyzed, finally the simulation is carried out on the software receiver.
