Abstract

Currently, there are five testing satellites of BeiDou Global Satellite Navigation System broadcasting new signals. Quality analysis of testing satellite observations is a significant content for the verification of the new signal system. Based on single station measurement of BeiDou testing satellites, the code minus phase combination (CC) and multipath combination (MP) are employed to analyze the code noise and multipath errors of civil signals and Bs signal of the test satellites. The result shows that the pseudorange measurement accuracy of inclined geosynchronous satellite orbit (IGSO) satellite is better than that of the medium earth orbit (MEO) satellite; B2a+b signal has the highest pseudorange measurement accuracy as well as the best anti-multipath performance, while the B1C signal performs the worst in both aspects; the pseudorange measurement accuracy of Bs signal is rela-tively poor, yet better than that of the B1C signal and a systematic error related to elevation exists in the code multipath series of Bs signal with its maximum value up to 0.5 meter.
