Abstract

The Channel Bias of GNSS Receiver affects the precise measurement of navigation signals. It is important to correct the channel bias of GNSS Receiver for precise orbit and clock products in multi-GNSS data analysis. Based on the refined pseudorange observation error mode, the paper proposes a new method of measuring channel bias of GNSS Receiver by using GNSS simulator, which can measure the bias in the same frequency of the same system, between the different frequencies, between the different systems. Finally, this paper uses this method to test three types of iGMAS receivers, the results show that the channel bias in the same frequency is about 0.01 ns, while that in the different frequencies and the different systems is about 0.1 and 20 ns respectively, and all these bias are related with the receiver type.
