摘　　要：本文分析了单自由度陀螺罗盘在陀螺力矩、空气阻尼、摩擦力矩和悬挂带扭矩作用下的运动规律及其寻北原理，指出由于单自由度陀螺罗盘的摆动周期比二自由度陀螺罗盘的摆动周期显著缩短，定向速度可成倍提高，定向精度也有望提高。This paper studies the law of notion of a single degree of freedom gyrocompass under the action of gyroscopic moment, air dumping, friction moment and the torgue of band suspension, and analyses it's principle of north seeking, then points out that since it's pendulus period is greatly shorter than a two degree of freedom gyrocompass, it is times faster in surveying speed, and more accurate in orientation. This is a great progress on land engineering surveying for meridian determination.
