ZENG Qing-hua, LIU Jian-ye, LI Rong-bing. Research on DCA of magnetic deviation based on constant attitude errors[J]. 2006, (4): 31-34. DOI: 10.13873/j.1000-97872006.04.011.
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.
