Abstract
The north finder error was studied using the basic theory of strap-down inertial system. It is found that when the attitude angle is nonzero, the azimuth error is partly caused by the disagreement of coordinates with latitude error. And based on this, the theoretical criteria of the azimuth and attitude compensation were partially put forward. Simulation and test results show that the azimuth error is the function of azimuth, latitude and attitude.
