| Abstract: | Conic error is the main error source for strapdown inertial system, especially for laser gyroscope strapdown inertial system. In order to improve the navigation accuracy of laser gyroscope strapdown inertial system and prevent the accumulation of attitude error, the conic error characteristic and its compensation methods are deeply studied in this paper and eight common algorithms for conic error compensation are put forward also. Based on the real application background of laser gyroscope inertial unit, Trajectory simulation research is conducted and the conic error influence on navigation accuracy of laser gyroscope inertial system and its compensation correction effect are together provided. |
| Keywords: | strapdown inertial system conic error attitude updating rotational vector error compensation |
