Drilling field: The north azimuth angle is an important attitude angle reference datum for the drilling rig and an important parameter to achieve precise operation of the drilling rig. Since there is no GPS-assisted north direction information in coal mines, and geomagnetic information cannot be used to find north due to ferromagnetic interference, a north seeker is the best solution to achieve rapid and accurate north search by using fiber optic gyroscopes that are sensitive to the earth's rotation component. The fiber optic gyroscope has strong anti-interference ability and large measurement range. It is the core component of the north seeker and is very suitable for use in drilling and mining operations.

Radar: System north seeking is an essential function of the radar system. The north seeker is mainly used to automatically measure the angle between the normal line of the radar antenna and true north when moving positions. The prerequisite for realizing this function is that the pointing of the north finder should be parallel to the normal line of the radar antenna. However, in actual use, it is impossible to achieve complete parallelism between the north-seeking direction and the antenna normal. There is a fixed error between the two, which must be eliminated through azimuth calibration.

In addition, fiber optic gyro north seekers can also be used in modern land weapons and equipment. Inertial north seekers with gyroscopes as the main sensor are important equipment in modern warfare to ensure accurate weapon strikes. High-precision orientation is a prerequisite for the strike accuracy of modern land weapons, especially land-based long-range weapons. Orientation accuracy is an important factor in ensuring the lethality of weapons within the range. As one of the important achievements in the application of inertial technology, the gyro north seeker has high orientation accuracy, short measurement time, and is not restricted by climatic conditions. It can measure orientation all-weather and autonomously without relying on any external information. It is a high-precision orientation benchmark system's preferred device.Please see parameters for details：
