The global positioning system （GPS） data acquired by the HY-2 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 the Centre National d’Etudes Spatiales （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.
