摘要
通过分析罗差形成的原因 ,提出一种有效的罗差修正方法及基于最小二乘法的确定罗差系数的方法。完成了以 AT89C5 2为主控制器的小型固态航姿系统软硬件设计。采用主控制器与手持控制器协同工作的设计思想。使系统在工作现场的补偿过程变得简单快速。实验结果表明 ,该系统修正效果明显 ,工作稳定可靠。
Intelligent magnetic-resistance sensor is introduced. After analyzing the cause of deviation, an effective method about compensation is presented and the compass diviation coefficients based on least square methods are confirmed. The design of hardware and software for small solid-state heading and attitude system using AT89C52 as main-controller is carried out. The design concept in which main-controller cooperates with hand-held controller is adopted, and it makes the compensation process at workshop simpler and quicker. Experimental results show that the system has an obvious compensation effect and is stable and reliable in operation.
