The data processing requirements of FOG north seeker are different from the data processing methods used in the navigation field. It does not have too stringent requirements for real-time performance. It can even completely separate data acquisition and data processing, and pays more attention to stability and accuracy. In order to improve the north-seeking accuracy of the fiber optic gyro north seeker, this article believes that it can be improved through three aspects:

(1) First, improve the north-seeking accuracy of FOG north seeker by improving the performance of the gyroscope components
(2) The second step is to improve the north-seeking scheme to improve the north-seeking accuracy of the north-seeking instrument
(3) The last step is to mine the patterns behind the data and improve the north-finding accuracy through data processing

In an ideal state, the output value of fiber optic gyroscope can truly reflect the angular rate of the current system where the gyroscope is located. However, during the actual test process, due to the noise generated by the internal components of the gyroscope and the continuous impact of the external working environment on the gyroscope output value, interference noise and drift will inevitably exist in the gyroscope output value. The existence of these noises greatly interferes with the north-seeking measurement accuracy of fiber optic gyroscopes. Therefore, when FOG north seeker performs north seeking directional measurement, we can conduct in-depth analysis and research on the internal hidden rules of the output signal of the fiber optic gyroscope, so that we can take effective error suppression measures and compensation methods to improve the accuracy of its directional measurement.
