重力场和地磁场综合匹配在导航中的运用

Application of Gravity and Geomagnetism Matching in Navigation

以重力等值线图辅助惯性导航匹配为主要的匹配方法,同时用地磁等值线图来修正重力辅助惯性导航中的误差,以达到航迹的精确匹配。最后利用重力场数据和地磁场数据进行仿真,实验结果表明该算法相比于使用单一的惯性导航算法,提高了匹配精度。

Both gravity matching and geomagnetism matching methods were utilized to correct the errors of the inertial navigation system （INS）. Using the gravitational map determine the path, while utilizing the geomagnetic map to correct those errors of geomagnetic matching. At last, simulation results showed that this matching method can improve the performance of the whole navigation system relative to the simple inertial navigation method.
