Abstract
After a sketch of history of gyroscope technology, the dynamic law of a gyroscope and its specialization to the suspended gyrocompass are outlined. The equations of motion of a north-seeking gyro are reviewed forming the base for observation techniques. Following a state-of-the-art report, the relations between the observables and the final azimuth are fully discussed and actions and precautions required for precise results are proposed. With modern instruments and observation methods it is presently possible to determine an azimuth with a standard deviation of 3″ to 6″ within less than one hour. The principles of non-rotating optical gyroscopes are presented and their potential as alternatives to conventional instruments is discussed.
