Gyro north finder field calibration device

Abstract

The invention discloses a gyro north finder field calibration device. Supporting regulating feet are fixedly arranged at the bottom of a main body seat; a datum mounting base is arranged at the upperpart of the main body seat; a parallel light pipe is mounted on the datum mounting base by a parallel light pipe regulating device; the parallel light pipe is mounted on a box body with a plane mirrorand a north datum lead-out block; a gyro theodolite is mounted at one side of the datum mounting base by a regulating supporting frame. According to the invention, the gyro theodolite is adopted to determine a north datum for the parallel light pipe, and thus, the gyro north finder field calibration device is convenient to operate and high in accuracy; the gyro theodolite and the parallel light pipe are of an integral structure, and thus, the gyro north finder field calibration device has the advantage of convenience for carrying and can implement field calibration of a gyro north finder; thenorth datum lead-out block leads out a plane and the north is determined for once by the gyro theodolite, calibration of other gyro north finders can be implemented, so that the measurement process is simplified, and detection efficiency is improved. The gyro north finder field calibration device is suitable to use as a gyro north finder field calibration device.

Description

technical field

[0001] The invention relates to a gyro north finder in the field of metrology, in particular to on-site calibration of a gyro north finder, in particular to an on-site calibration device for a gyro north finder. Background technique

[0002] The gyro north finder is a sensor that independently determines the true north value of the attached carrier by measuring the angular velocity of the earth's rotation. Because it is not disturbed and affected by the external magnetic field or other environments, it is widely used in radars, antennas, and military vehicles. and other fields.

[0003] The high-precision gyro theodolite’s orientation and aiming for the mobile launch of long-range weapons is the key equipment for the mobile launch of missiles from unprepared positions, and it also plays an important role in improving the response speed of artillery and effectively exerting the power of artillery.

[0004] Because the gyro north finder is an instrument for or...
