固体潮模型在GPS/BDS PPP中的影响分析
Influence Analysis of Earth Tide Model in GPS/BDS Precision Point Positioning
摘要
Abstract
Aiming at the problem that the earth tide correction model will have an impact on the precision point positioning(PPP)of GPS/BDS,we used IERS2003 earth tide correction model to quantitatively analyze the positioning results of GPS,BDS-2,BDS-3,BDS-2+BDS-3 and GPS+ BDS-2+BDS-3 respectively.The results show that the earth tide correction model will have a great impact on the PPP of each system.The aver-age correction of GPS PPP results in N,E and U directions are increased by 1.06 cm,1.01 cm and 3.77 cm respectively,BDS-2 PPP increased by 0.87 cm,1.09 cm and 3.48 cm,BDS-3 PPP increased by 1.30 cm,1.32 cm and 5.29 cm,BDS-2+BDS-3 PPP increased by 1.45 cm,1.85 cm and 6.37 cm,GPS+BDS-2+BDS-3 PPP increased by 1.71 cm,1.83 cm and 6.41 cm.关键词
