【摘要】 由于地磁变化场会影响地磁场的测量,从而对地磁导航的精度和可靠性产生一定的负面影响,本文通过设计飞行器地磁匹配导航仿真实验,对地磁变化场中主要因素的影响程度进行了研究。从仿真结果分析可以看出,不同磁场成分对地磁导航的影响不尽相同,因此在地磁导航中需要对变化场进行补偿或者采用优良的匹配算法,以进一步提高地磁匹配导航的精度。更多还原

【Abstract】 geomagnetic variations affect the measurement of geomagnetic field,thus negative impaction will produce on precision and reliability of geomagnetic matching navigation.This thesis conducted research on the influential degree of main elements in geomagnetic variation through simulative experiments of geomagnetic matching navigation for flying objects.According to the analysis of simulation results,the influence of different composition on matching algorithm is also different.Thus,in order to further improve the precision of geomagnetic matching navigation,it is necessary to compensate the variations,or to adopt the superior matching algorithm.更多还原
