用于短时定位的MEMS旋转调制惯性导航系统
MEMS Rotation Modulation Inertial Navigation System for Short-Time Positioning
摘要
Abstract
Rotation modulation technology can effectively improve the navigation accuracy of the inertial navigation system by the periodic rotation of the rotation mechanism. First,the error characteristics of the inertial navigation system and the rotary modulation inertial navigation system under short-time navigation are analyzed in detail. Then, aiming at the practical MEMS rotary modulation inertial navigation system,its system composition is introduced,and its rotation scheme and navigation algorithm are determined through analysis and comparison. At the same time,the error introduced by the rotation mechanism is analyzed and compensated. On this basis,static and dynamic experi-ments are carried out and the accuracy is evaluated by the time real root mean square error( TRMS) method. The ex-perimental results show that the position accuracies of the rotation modulation state in the static and dynamic experi-ment are about 10 times and about 3 times than that of the non-rotation state.关键词
