A dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG) is presented in this paper. In this scheme  the sine output signal of the FOG was sampled and disposed  and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the platform base tilt was compensated by an accelerator  Allan standard deviation is used to analyze the random drift of FOG  and establish the random error mode of FOG. The FOG north-finding and laser collimation theodolite are assembled to achieve orientation and aiming integral  which lays foundation for switching to project application. 2007 IEEE.
