【摘要】：采用边界分析方法分析新一代重力测量卫星3个核心载荷——星间测距系统、非保守力测量仪和定位接收机的误差对恢复重力场的影响,提出新一代重力测量卫星的核心技术指标。分析表明,星间变率测量精度10~30nm/s、非保守力测量精度(1~5)×10-11 m/s2、定轨精度2~3cm时,可实现分辨率100km、精度1~2mGal的重力场测量。本文结论可为新一代重力测量卫星设计提供技术参考。
[Abstract]:The influence of the errors of the three core payloads of the new generation gravity measurement satellite, the non-conservative force measuring instrument and the positioning receiver, on the recovery of gravity field is analyzed by using the boundary analysis method. The core technical index of the new generation gravimetric satellite is presented. The analysis shows that when the accuracy of intersatellite variability measurement is 10 ~ 30nm / s, the accuracy of non-conservative force measurement is (1 / 5) 脳 10 ~ (-11) m / s ~ (-2), and the precision of orbit determination is 2~3cm, the gravity field measurement with a resolution of 100km and an accuracy of 1mGal can be achieved. The conclusion of this paper can provide the technical reference for the design of the new generation gravity survey satellite.
