高精度惯性导航系统对重力场模型的要求

The Requirement of Gravity Model for INS with High Precision

  • 摘要: 分析了采用现有重力场模型EGM96进行重力补偿和INS所能达到的定位精度,分析了实施GOCE任务和改进的重力场模型对INS的定位精度的影响,并给出了未来高精度纯惯导系统对重力场精度的要求。

     

    Abstract: With the development of inertial sensor,gravity disturbance have become the uppermost error source of INS use of the normal gravity in the mechanization equations.So the improvement of INS position accuracy by use of the EGM96 model and the improved gravity model after GOCE mission is analysed.Finally,the requirement of gravity accuracy is deduced for the pure INS with high precision in the future.
