WT5BZ]A new type gyro-theodolite scheme based on the fundamental law and kinematic behavior of gyroscope is presented. In this scheme, a mechanics model of high speed gyroscope rotor has been established, by which the angular velocity of earth rotation was educed. The advanced CCD optoelectricity measuring technology was adopted to sample the data of principle curves, and the real north of surveyed point was calculated with the least square method. The coordinate azimuth of the missile, which is going to be launched, was determined. The gyro theodolite system is especially suitable to military applications because of its fast reaction, high precision and low cost. [WT5HZ]
