| 摘 要： | 在传统二位置寻北方案基础上,针对光纤陀螺寻北仪提出了一种新方案。它将传统的水平面内旋转寻北改为竖直面内翻转寻北,所以不再需要像以往寻北仪那样在寻北时间和寻北精度之间进行折衷处理,可以在减少寻北时间的同时,提高寻北精度,并使寻北仪对光纤陀螺仪（FOG）和转台性能的依赖程度大幅降低。

| Abstract: | A new scheme which is improved based on traditional north determining scheme by two-position for a IFOG north seeker is presented. It seeks north by vertical rotation instead of horizontal rotation. It changes the situation that compromise should be made between north seeking time and north seeking precision. It shortens the procedure to find the north, increases the north seeking precision and greatly reduces the dependence on performance of the IFOG and rotated disk. |
