摘要
建立了单轴旋转式捷联惯导系统数学模型和仿真模型,采用的导航算法能有效避免转台测角误差对系统定位精度造成的影响;仿真结果表明旋转IMU能提高抑制惯导定位误差的累积,提高惯导定位精度、姿态精度和速度精度也同时得到提高。
The mathematical model and simulation model of single-axis rotation strap-down inertial navigation system(SRSIN) is established.The algorithm this paper adopted can avoid the navigation error which caused by measuring angle error of rotating platform.The simulation result shows that rotating IMU can highly suppress the divergence of position error,thus position accuracy as well as attitude and velocity accuracy is enhanced.
