摘要：
Four new BDS II satellites have been launched which are named C31 (IGSO), C32 (IGSO), C33 (MEO) and C34 (MEO) separately. Their data qualities would affect the process of BDS globalization directly. In order to analyze the observation data quality of new navigation satellites, four indexes have been processed which contain data integrity rate, multipath, signal-to-noise ratio (SNR) and cycle slip ratio. The OBSQC software was developed to process the iGMAS data from September 8, 2016 to October 8, 2016. The experiment results show that the B1 and B3 data integrity rates of new navigation satellites are better than 95% The SNR results of the new IGSO satellites are better than that of the IGSO working satellites while the SNR results of the new MEO satellites are quite similar to that of the MEO working satellites. In addition, the SNR values of the MEO satellites are better than that of the GPS MEO satellites. As for the multipath error, the results of the new navigation satellites are slightly better than that of the BDS working satellites and the GPS satellites.
