BDS卫星天线相位偏差对PPP法估计ZTD的影响
Influence of BDS antenna phase offsets on zenith tropospheric delay estimation with PPP method
摘要
Abstract
In order to analyze the influence of the BDS satellite antenna phase offsets on the ZTD estimation,the MGEX model and the ESA model are respectively used to correct the antenna phase offsets,and 8 MGEX stations observed data is used to estimate ZTD by using the PPP method.The results show that,taking the GPS ZTD obtained by the PPP method as reference values,the precision of ZTD can be improved apparently with correction model.The ESA model shows better correction compared with MGEX model and fixing station coordinates is also useful for decreasing system error and enhancing external accuracy.In all,the ESA model is advised for BDS satellite antenna phase offsets correction.关键词
