摘　　要：为实现陀螺寻北仪在大偏北角情况下粗寻北,在大偏北角情况下,该文分别对不跟踪和跟踪状态下的陀螺运动特性进行分析后,针对陀螺运动特性,提出不跟踪及跟踪状态下的两种大偏北角的粗寻北方法,并分析了两种粗寻北方法;最后,对跟踪状态下的大偏北角粗寻北方法进行试验验证,分析了方法的有效性及寻北精度不足的原因,并根据分析结果提出设计高精度伺服系统的必要性。In order to achieve the rough north-seeking in large azimuth,the motion characteristics of pendulous gyroscopes in both non-tracking state and tracking state in large azimuth are analyzed respectively.Then based on the motion characteristics of gyroscopes,two rough north-seeking methods are put forward and analyzed in nontracking state and tracking state.Finally,the experiment on the rough north-seeking method in tracking state is carried out.The results demonstrate the feasibility of the method and the reasons of low precision are analyzed.The necessity of designing high-precision servos system is presented on basis of the results.
