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 proposed. 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 improving 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 laboratory, 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 divergence speed is very slow.
