电子罗盘最佳椭圆误差补偿方法
Error Compensation Method for Electronic Compass Based on Best Ellipse-Matching Error Compensation Algorithm
摘要
Abstract
Direction data of electronic compass can be used as the initial alignment data of the navigation system, however,compass deviation grows while external magnetic field produces its impact upon electronic compass in practical utilization. Compass deviation must be offset so as to improve the initial alignment precision of the navigation system. In this paper,the best ellipse-matching error compensation algorithm was proposed and applied to initial alignment of the SINS-GPS navigation,the compensation proposal and relative data were also given in detail. Experiment showed that best ellipse-matching error compensation algorithm can effectively eliminate the compass deviation,compass system after compensated can be used in common navigation initial alignment field and other areas.关键词
