Quality Analysis and Constellation Geometric Performance Evaluation of New Signals B2a and B2(B2a+b) of BDS-3
Abstract Based on the latest MGEX station that can receive the new signals B2a and B2(B2a+b) from BDS-3, we analyze the carrier noise ratio of the BDS-3 signal, multipath and the position dilution of precision of the satellite(PDOP). The results show that compared with GPS, the CNR B2(B2a+b)>B2a≈L5>B3≈B2b>B1≈L1>L2, multipath B2(B2a+b)<B2a≈L5<B3≈B2b <L2<L1<B1. The PDOP value of BDS-3 is similar to GPS, and the PDOP is significantly reduced after being composed of multiple systems with GPS.
Key words :
BDS-3
B2a and B2(B2a+b)
