| 摘 要： | 采用2009-11-01~2010-01-31三个月的SLR观测数据，对GOCE卫星运动学轨道 PKI（precise kinematic orbit）进行检核。基于残差分析发现，SLR观测存在测站时距系统性偏差。消除测站时距偏差后，GOCE卫星PKI精密轨道的外符合精度达到1.5 cm。

| Abstract: | In this paper we present the method of satellite orbit validation with SLR measurements, and use SLR data observed from 1 November 2009 until 31 January 2010 (3 months) to validate the GOCE PKI (precise kinematic) orbit. Based on residual analysis, we find that system error due to station time bias and range bias exits and has not been removed in the SLR observation. After modeling and fitting the station time bias and range bias, we achieve the GOCE PKI orbit precision at the level of 1.5 cm. |
