Abstract
A hexahedral prism and IMU installation error calibration technique based on turntable transmission is proposed. It effectively simplifies the calibration process of precise POS and SAR radar installation errors. Based on the zero position of the turntable, high-precise optical equipment was used to calibrate the hexahedral prism and the zero position of the turntable, then calibrated IMU and turntable zero position to realize the installation error of hexahedral prism and IMU through the error attitude matrix conversion. The calibration method is much simple and accurate. Test result shows that the heading angle and attitude angle calibration repeatability is better than 5”.
