【摘要】 速率方位惯性平台/重力匹配组合导航系统是一个简易的重力无源导航系统,它可以保持水下运载体长时间高精度隐蔽航行。给出了该组合导航系统的工作原理、数学模型以及计算机仿真结果。仿真结果表明速率方位惯性平台/重力匹配组合导航系统定位误差不再随时间增长,运行30多个小时其组合导航系统定位误差不超过惯导系统误差的20%。更多还原

【Abstract】 Rate azimuth inertial platform/gravity matching integrated navigation system is a simple passive gravity navigation system which can keep vehicle under water navigating covertly with high precision in a long time, The principle and mathematical model of the system are introduced, and the simulation is carried out. The simulation results show that the integrated navigation system can bound position error to 20 percent of inertial navigation system over thirty hours’ navigation.更多还原
