光纤捷联惯导系统的双轴旋转调制方案
Dual-axis rotating scheme for fiber strapdown inertial navigation system
摘要
Abstract
In order to further counteract the incomplete modulation to inertial sensors’ scale errors and installation errors in the commonly used dual-axis rotating scheme at present, an improved dual-axis rotating scheme was pro-posed.By analyzing the propagation characteristics of system errors stage by stage, the rotation axis and direction of each rotation were designed respectively so as to counteract the residual errors of device in sequence, thereby im-proving the modulating effects of dual-axis rotating and meeting the self-navigation accuracy requirements of SINS ( strapdown inertial navigation system) .The proposed scheme was compared with the commonly used scheme in la-boratory, and simulation and experiment results showed that the amplitude of the improved scheme’ s velocity errors and position errors curve is remarkably smaller than that of the commonly used scheme, and the errors’ overall di-vergence speed is very slow.关键词
