| Abstract: | Based on the earth gravity field measurement element, the technique requirements about the earth gravity field survey are analyzed in accordance with the opinions of the model solution of the local gravity field, the region gravity field, and the global gravity field. In the concept of orbit determination using high-low satellite to satellite tracking distance measurement data and distance variation measurement data, the development about satellite to satellite tracking gravity survey system is described. According to the technique connotation of satellite gravity survey system, the measurement innate characters of the earth gravity field research about high- low satellite to satellite tracking measurement model and high-low-low satellite to satellite tracking measurement model are analyzed. |
