Abstract

Abstract: In view of the difference in the precise point positioning performance of different dual-band combinations of BDS-2, BDS-3, and BDS-2/BDS-3, this paper analyzes the PPP precision of seven different dual-band combinations in BDS-3 and compares it with BDS-2, BDS-2/BDS-3 same frequency dual frequency combination PPP precision comparison. The results show that the precision of BDS-2 and BDS-3 at the same frequency dual-frequency combination PPP is equivalent to the first convergence time. Among them, the precision of B2I/B3I combination PPP is the worst, and the precision of BDS-2/BDS-3 positioning precision and the first convergence time compared with the single situation, it has been greatly improved. In terms of BDS-3 dual-band combined PPP, the precision and first convergence time of the B2b/B3I combined PPP are the worst of the BDS-3 seven dual-band combined PPP, and the positioning performance of the other six dual-band combined PPPs is comparable.

Key words: BDS-3, precise point positioning, dual frequency, precision, convergence time
