To improve the accuracy of the vehicle-based SINS and reduce the time of calibration, it introduces a new multi-position calibration method in outfield conditions according to the using features of the Vehicle-based SINS based on extended observation. It raises a new filed calibration method with extended information of gyroscope and analyzes its observability, then conducts experiments. The test...
When accelerometer is installed, errors would be produced, which will greatly degrade the measurement accuracy, so to the tracking precision while being applied in the compound control. We make the experimental analysis for the accelerometer installation, in which the accelerometer is installed parallel to the azimuth and 30° degree away the azimuth. The data are dealt with and compared with the theoretical...
