| 摘 要： | 针对具有恒定俯仰角度载体的磁航向罗差标定和补偿问题,提出了一种用于磁罗差修正的偏差补偿算法(DCA)。通过DCA的原理分析和证明得出:该算法对具有恒定横滚角度和俯仰角度的磁航向罗差修正均有效,经过DCA补偿的磁航向角度误差在±0.3°以内,满足飞机的航向标定要求。

| Abstract: | To calibrate and compensate the compass error of magnetic heading in a carrier with constant pitch angle,the deviation compensation algorithm(DCA) for magnetic deviation compensation is put forward.The introduction and the analysis of DCA theory indicate that DCA is very useful for compensation with both constant pitch and roll angles,and the DCA modified error of magnetic heading is restricted within ±0.3° which can satisfy the heading calibration requirement of the plane. |
