ACCURACY IMPACT ANALYSIS OF KINEMATIC ORBIT DETERMINATION BASED ON EPOCH PHASE DIFFERENCE
摘要
Abstract
The kinematic orbit determination of LEO satellite software named GNSS_LEO_KPP is developed, and the observation data of GRACE_A and GRACE_B satellites in 7 days from DOY220/2011 to DOY226 / 2011 are calculated. Compared with the JPL precise orbits, the accuracy of final kinematic orbit can reach 10-20 cm. The results show that: the priori orbit quality has a certain level of impact on the final kinematic orbit quality, so we could use the iterative loop kinematic orbit as a prior orbit, and the final kinematic orbit accuracy can be maintained in decimeter or sub-centimeter level.关键词
