【Abstract】 The development of both SLR and GPS tracking techniques is simply described. The progress of laser ranging to GPS-35,36 satellites in recent years and the situation of application research are introduced in detail. The preliminary results of residual analysis are shown,and it is pointed out that the present sparse laser ranging data of GPS satellites are very valuable for precise orbit determination of the satellites and station coordinate solution. Meanwhile, the strengths and weaknesses of microwave and laser tracking of GPS satellites have also been briefly reviewed. The suggestion combining data of the GPS and SLR measurements from GPS-35,36 sattellites in a common solution concerning application study is presented. Finnally, some comprehensive comments on the further application research are also given.更多还原
