| 摘 要： | 为了降低重力无源导航系统的成本,提出在速率方位平台上放置一个高精度的重力敏感器,构成一个具有导航与重力测量功能的导航重力测量系统,该系统再加上重力数字图就组成了一个重力无源导航系统.为此,论文对速率方位平台惯性导航系统进行了研究,建立了速率方位地平坐标系,给出了它的系统计算方程和误差方程,进行了误差分析,并且运用计算机仿真了无阻尼和有阻尼时的RAPINS的误差特性.仿真结果表明由中等精度惯性元件构成的无阻尼RAPINS误差积累很快,阻尼后其平台角误差和方位角误差都不大,能够满足重力测量和基本导航要求.

| Abstract: | To lower the cost of the gravity passive navigation system,a rate azimuth inertial platform with a gravity sensor on it was put forward to constitute a navigator with gravity measuring,combined with digital gravity map,the system would come to a simple passive navigation system.Some algorithms and equations were lied out,simulations of pure rate azimuth inertial platform navigation system and the system with damping were carried out.Simulation results showed that the errors of pure rate azimuth inertial pla... |
