利用卫星激光观测对大气折射模型的综合比较

Analysis of Models of Atmospheric Refraction with SLR Observations

利用3天22个测站的Lageos-1激光测距资料,解算出卫星的一条轨道,再利用此轨道和地面测站检验原有的大气折射模型。得到定轨常用的Marini(1973)模型以及Yan(1999)模型、UNSW932模型、Cfa2.2(1985)模型等的改正特点。

We solve the orbit of the satellite Lageos-1 with 3-day observations at 22 stations.We derive the correction characteristics for the Marini（1973）,Yan（1999）,UNSW932,and Cfa2.2（1985）models of atmospheric refraction by comparing predictions from the models and solved orbit to observations at a station.
