| 摘 要： | 介绍了微机电(MEMS)惯性测量元件(IMU)的基本情况，总结了误差主要来源，根据公开文献介绍的性能测试参数，建立了动态误差模型，并与GPS测量的速度和位置组合，进行了导航系统的数学仿真。仿真结果表明，MEMS—IMU尚不能独立构成导航系统，但与GPS组合，则可满足低精度的导航要求。

| Abstract: | This paper introduced the basic development situation of Inertial Measurement Unit(IMU)of the Micro Electronic Mechanical System(MEMS ),and summarized the main error source.The dynamic error model was built according to the performance parameters supplied by the published literatures.Then the MEMS -IMU/GPS integrated system was established us-ing GPS velocity and position measurements,and the computer simulation was done as well.The simulation result shows that we can not establish a navigation system only by using MEMS -IMU.Integrated with GPS,the system will be well for the low precision navigation sys-tem. |
