摘　　要：在MEMS-INS中引入旋转调制技术,通过MEMSRM惯性导航系统进行旋转调制,实现快速导航定位的目标。实验分析得到:南向精度比原先提升了22倍,北向误差率达到了原先的16倍,并且最低也能够提高1倍与6倍,本文使用的旋转调制技术与解算方案具备可行性。当时间增加后,MEMS-INS的位置误差与偏离程度更大,经过100s测试后,MEMS-RMINS比MEMS-INS的最大误差率提高了4倍左右。当导航时间延长后,将形成更大的MEMS-RMINS位置误差。采用旋转调制的方式可以使MEMS-RMINS定位精度获得较大改善,精度提升近3倍,满足某些应用场合的需求。In MEMS-INS,rotational modulation technology is introduced to realize rapid navigation and positioning through the MEMSRM inertial navigation system.According to the experimental analysis,the accuracy in the south direction is 22 times higher than before,and the accuracy in the north direction is 16 times higher than before,and the minimum is 1 times higher and 6 times higher.The rotary modulation technology and calculation scheme used in this paper are feasible.When the time increases,the position error and deviation degree of MEMS-INS are greater.After 100 s test,the maximum error precision of MEMS-RMINS is about 4 times higher than that of MEMS-INS.When the navigation time is extended,a larger MEMS-RMINS position error is formed.By means of rotating modulation,the positioning accuracy of MEMS-RMINS can be greatly improved,and the accuracy can be improved by nearly 3 times to meet the needs of some applications.
