卫星重力测量系统的发展和测量模式

摘要

从地球重力场测量要素出发,按照局部重力场模型、区域重力场模型、全球重力场模型求解的发展思路,分析了对地球重力场测量技术手段的要求.根据高—低卫星跟踪卫星的距离和距离变率开展定轨研究的概念,梳理了卫星跟踪卫星重力测量系统的发展.针对卫星跟踪卫星重力测量技术的内涵,分析了高—低卫星跟踪卫星测量模式(SST-hl)和高—低低卫星跟踪卫星测量模式(SST-hll)的地球重力场测量本质.%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.
