The swing equation of gyro theodolite is nonlinearity, and data processing result is not good after linearizing. Based on analyzing some tradition methods, this thesis puts forward a kind of new processing method, that is: observation values are divided into groups that a group includes three values, and then solves the approximate values of initial amplitude, attenuation coefficient and north direction of gyro theodolite. At last, most probable value and precision of gyro theodolite's true north are solved by means of simple-easy and close methods, and variance of reversal point is estimated with the principle of component estimation.
