基于星载 GPS 数据的 GRACE 卫星动力学法定轨
GPS-Based Dynamic Orbit Determination of GRACE Satellite
摘要
Abstract
Using zero-difference satellite-borne GPS data ,the orbit of GRACE A satel-lite by dynamic method with GPS observations is determined during the period from January 11 to 18 ,2012 .The orbit results will be compared with RSO which were released by GFZ , and be verified by SLR observation .The comparison results show that the accuracy of orbit determination can meet the requirement of LEO satellite .Compared with the RSO orbit in X ,Y ,Z direction ,the average of RMS is 4 .7 cm ,4 .3 cm and 4 .9 cm respectively .Calibra-ted with SLR observation ,the mean of residuals is -1 .6 cm ,and the RMS is 4 .7 cm .关键词
