Precise orbit determination technology based on dual-frequency GPS solution for HY-2A satellite

Lin Mingsen,Wang Xiaohui,Peng Hailong,Zhao Qile,Li Min

Strategic Study of CAE 2014, Volume 16, Issue 6,   Pages 97-101

Abstract:

The GPS data acquired by the HY-2A satellite GPS receiver have been used in a dynamic orbit determination, which was based on the description of the gravitational and nongravitational forces in the equations of motion. The GPS carrier data were processed in a difference mode to remove clock errors. Simultaneous estimation of the HY-2 satellite orbit and GPS orbit was performed using the data in March (2012). The resulting HY-2 satellite orbits have been compared with CNES orbits and reduced dynamic orbits for GPS/DORIS/SLR strategies, and in the meantime confirmed with SLR validation. The radical component of the GPS orbit was found to agree with better than 3 cm.
