接收机PCV对北斗三号非组合PPP解算的影响
Research on the influence of receiver PCV on the solution of uncombined PPP of BDS-3
摘要
Abstract
Aiming at the impact of the phase center variations(PCV)of the receiver antenna on the uncombined precise point positioning(UPPP)solution parameters of the BeiDou-3 Navigation Satellite System(BDS-3).The final products from the IGS data center of Wuhan University were selected,and taking the BRUX station as an example,an experimental analysis was carried out on the coordinate accuracy,zenith tropospheric delay(ZTD)accuracy,receiver clock error accuracy,and slant total electron content(STEC)during the data solution of a total of one week from the 90th to the 96th day of 2024.The results show that the millimeter-level PCV error has a greater impact on the elevation direction and a relatively smaller impact on the horizontal directions;PCV has a significant impact on the clock error results,and the difference between the results with and without PCV error correction is approximately 2 ns(about 0.6 m);the PCV error has a large impact on the ZTD,with the accuracy of the ZTD being 15.7 mm without PCV error correction and 7.6 mm after PCV error correction,and the accuracy is nearly doubled;the PCV error has a large impact on the STEC during the UPPP convergence stage,reaching 0.3 TECU(about 0.047 m),and its impact on the STEC can be basically ignored after convergence.关键词
