Embodiment Construction

[0012] As shown in the figure, a support adjustment foot 1 is fixed on the bottom of the main body seat 2, and a reference mounting seat 3 is provided on the upper part of the main body seat. The light pipe is installed on a box body with a plane mirror 6 and a northward reference lead-out block 7, and a gyro theodolite 8 is installed on one side of the reference mounting seat through an adjustment support frame 9.

[0013] Installation and use:

[0014] The main body support and adjustment feet are used for the stable support and level adjustment of the main body, and the stable support is realized through the threaded rotating ball head and the ball head cup support structure; the main body is an integrated structure, and the adjustment support frame is installed on one side for installation and adjustment of the gyro theodolite , the other side is installed with a reference mount; a collimator and a collimator adjustment device are fixedly installed on the reference mount, ...

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...
