Systematic Calibration Method for High-Precision Strapdown Inertial Navigation System
摘要
Abstract
Aiming at the large error of current calibration method, and error is increased when position departure increasing, put forward a iterative solution method. Based on the general output model of the high-precision strapdown inertial navigation system (SINS), the error model of the output can be derived. Then through proper positions and rotations, exciting speed error of the navigation systems, the error parameters can be deduced. Then with iterative algorithm, model parameters can be corrected continuously and navigation error would decrease as well. The analysis results prove that the method is very simple, has high calibration precision and without strictly level and north seeking. It meets requirements of navigation with high practical value in engineering.关键词
