Description

Triaxial integration laser gyro combination

Technical field

The utility model relate to a kind of modern aviation, navigation, space flight and etc. three laser gyro inertial navigations combinations of widely used a kind of inertial navigation instrument in the field, especially relate to a kind of triaxial integration laser gyro.

Background technology

Modern gyroscope is a kind of instrument that can accurately determine the orientation of moving object, it is widely used a kind of inertial navigation instrument in modern aviation, navigation, space flight and the national defense industry, its development is to the industry of a country, and national defence and other high-tech development have crucial strategic importance.Lasergyro belongs to wherein a kind of, and general lasergyro comprises members such as resonator cavity, mechanical hull and frequency stabilization circuit module, dither circuit module, constant-current circuit module.

In the prior art, three laser gyro inertial navigation combinations are that three lasergyro are installed in respectively on the support that processes, for guaranteeing three laser gyro inertial navigation work in combination quality, it is measured accurately, the mutually orthogonal error of the installed surface of its support need be less than 0.005mm.And existing three laser gyro inertial navigations combination, owing to be that three lasergyro are directly installed on together, so its whole volume, weight are all bigger, not only installation and removal are all inconvenient, and make that the rigging error when installing is very big, and do not reach requirement, influence its work quality.

The utility model content

Technical problem to be solved in the utility model is in order to overcome above-mentioned the deficiencies in the prior art, and provides a kind of volume little, lightweight triaxial integration laser gyro combination, makes it be easy to installation and removal and can reduce its alignment error.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of triaxial integration laser gyro combination, comprise the mechanical hull resonant cavity, and its improvements are three resonator cavitys are installed in the mechanical hull in mutually orthogonal mode.Specifically only design a mechanical hull, the mode with mutually orthogonal of three resonator cavitys in original three lasergyro is installed in this mechanical hull; The mutually orthogonal mode of its axis is fixed on mechanical hull inside.

As further improvement of the utility model, also comprise the frequency stabilization circuit integration module, dither circuit integration module and the constant-current circuit integration module that are arranged at described mechanical hull inside.Specifically with frequency stabilization circuit modules different separately in original three lasergyro, dither circuit module, constant-current circuit module totally nine integrated respectively three total frequency stabilization circuit integration modules, dither circuit integration module, constant-current circuit integration modules of turning to of circuit module; Again these three total frequency stabilization circuit integration modules, dither circuit integration module, constant-current circuit integration modules are installed in the described mechanical hull.The circuit connection has been simplified in this improvement, and electrical Interference is descended, and has reduced plug, socket quantity, makes that simultaneously volume and weight of the present utility model further reduces to alleviate, and makes it be easy to assembling.

The utility model can be used as members such as core component and support and installs to combine and promptly constitute three laser gyro inertial navigations combinations, is used for the accurate location of moving object.

Compared with prior art, the advantage of technical solutions of the utility model is:

The utility model has been installed in original three resonator cavity quadratures in the mechanical hull, simplified one-piece construction, the volume that makes lasergyro inertia make up reduces, weight reduces, and has reduced alignment error when being easy to mount and dismount, the accuracy of having measured when having improved its work; Be installed in this mechanical hull after further original nine circuit modules being reduced to three, so just further simplified one-piece construction, reduced volume, reduced weight, make it be easy to installation and removal more.
