    ER-GT-02 Ultra High Accuracy Gyro Theodolite

    Gyro theodolite is an instrument used to measure true north azimuth by combining gyroscope and theodolite through connecting mechanism. It uses the physical characteristics of the gyroscope itself (fixed axis and precession), the sensitive part of the gyroscope with the center of gravity moved down is used to sensitive the horizontal component of the earth's rotation angular velocity, and under the action of gravity, a northward precession moment is generated, so that the gyroscope spindle swings around the Earth's meridian plane, so as to determine the true north azimuth.

    The product adopts DC permanent magnet gyro motor, which can reduce the temperature rise of sensitive parts of the gyro and improve the stability of the equipment. The application of gyro fast braking technology can prolong the service life of the gyro motor, so that the instrument does not need to wait and can run continuously, with auxiliary functions such as deflection body, calibrator, and straightening.

    The product can find north with ultra-high precision, and its measurement principle is the integration method, which has the characteristics of strong anti-interference ability and high stability. The gyro-theodolite adopts an integrated body design (built-in battery), compact structure and stable performance. It has the functions of low position lock, automatic zero position observation, automatic north finding, automatic limit position, wide temperature compensation, etc. It is gradually iterating the limiter to provide the north finding accuracy of the reference plane azimuth and reduce the north finding time.

    Gyro theodolite is widely used in mine survey, engineering survey and military surveying, and is also an important supporting equipment for radar antenna orientation, UAV flight orientation, artillery and long-range weapon launching orientation.
