HY-2卫星双频GPS精密定轨技术
Precise orbit determination technology based on dual-frequency GPS solution for HY-2 satellite
摘要
Abstract
The global positioning system (GPS) data acquired by the HY-2 satellite GPS re-ceiver have been used in a dynamic orbit determination,which was based on the description of the gravitational and nongra-vitational 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 the Centre National d’Etudes Spatiales (CNES) or-bits and reduced dynamic orbits for GPS/DORIS/SLR strategies,and in the meantime con-firmed with SLR validation. The radical component of the GPS orbit was found to agree with better than 3 cm.关键词
