Analysis of the Initial Alignment of Rotary Fiber Inertial Navigation System
摘要
Abstract
For the purpose of getting higher navigation accuracy by rotating modulation techniques has become the research topic of inertial technology.According to the reliability and accuracy requirement of inertial navigation for mobile measurement system rotary fiber inertial navigation system,the coarse alignment with gravity transfer matrix and fine alignment with two position Kalman filter were proposed in this paper.The mechanism of transfer matrix of coarse alignment was analyzed. Initial strapdown matrix was designed by gravity and differential in inertial frame based on accelerometers.Fine alignments with Kalman filter for fiber inertial navigation were carried out baesd on IMU two optimal orientation by rotation.Turntable experiment results show that,inertial frame coarse alignment and two-position Kalman integrated fine alignment could be used to satisfy the requirement of rotary inertial navigation system initialization.关键词
