摘要
陀螺经纬仪是一种能测定真北方位的自主定向仪器,它在国民经济和国防建设中发挥着重要作用。文中研究了影响自动陀螺仪仪器常数的因素,讨论了在轨道交通地下定向中如何提高自动陀螺仪测量精度的方法与途径。
Gyro-theodolite is an equipment which can direct the real north independently, It has played a very important role in national economy and national defense. This article studies the factors of auto gyro-theodolite constant and discusses in how to improve the survey accuracy of auto gyr-theodolite when underground directing of metro.
