Celestial Mechanics: Satellite Laser Range, Orbit: Determination Of Precise Orbits
Scientific paper
Determination of LAGEOS satellite's precise orbits based on an analysis residual error of SLR data are introduced in detail. The method analyzing the data of satellite laser ranging (SLR)?the dynamical models used and the number of parameters estimated should be changed with the different purposes. The schemes were compared with each other and were analyzed with the number of parameters estimated and the residual errors in detail. The determination of precise orbits is the key of these. To acquire a precise orbit, the models determining the EOP were modified. The scheme being used by SHAO was selected from the several schemes. In this paper, the results of LAGEOS satellite's precise orbits from Dec. 31, 1998 to Jun. 29, 2001 are set out only. The results show that the root-mean square value of the residuals are less than 2cm. SHAO has begun the service of LAGEOS-1/LAGEOS-2 quick-look residual analysis since Oct.1, 1999. The results can be find on the intent address: http://center.shao.ac.cn/APSG/result
