【摘要】 本文结合我国发展卫星重力测量系统的迫切需求,针对如何确定重力卫星轨道参数的技术指标问题,从不同轨道高度和星间距离卫星所受到的扰动引力谱分量变化、卫星测量数据恢复的地球重力场模型精度这两个方面出发,确定了卫星轨道高度和星间距离的最佳范围.结果表明,我国将来低低跟踪模式中重力卫星的轨道高度应在400~500km之间,星间距离应为220km左右,这将为我国卫星重力测量系统的轨道参数指标设计提供一些参考.更多还原

【Abstract】 Combining with the exigent demand to develop satellite gravimetry system of China,aiming at the determination of technical indexes of gravity satellite‘s orbit parameters,according to the spectral components change of disturbing gravity and the Earth‘s gravity field model(EGM)precision recovered by satellite gravimetry data in different satellite orbit height and inter-satellite range,the optimal scopes of satellite orbit height and intersatellite range are determined.Results show that the satellite orbit height is between 400km and 500km,the intersatellite range is about 220km,and this will provide some references in the design of orbit parameters indexes of China‘s satellite gravimetry system.更多还原
