Abstract

The present invention relates to a hybrid inertial platform system, wherein the gyroscope combination of the platform uses the hybrid working mode of three orthogonally arranged single-freedom integrating gyroscopes and three orthogonally arranged MEMS gyroscopes so as to control and monitor the motion of the inertial space opposite to the platform body, and each frame and the base of the platform are respectively provided with three orthogonal MEMS gyroscopes so as to measure the complete information of the attitude angle actions of each part of the platform. According to the present invention, the inertial platform body, the frame and the base angular rate are measured by using the hybrid working mode of different types of the gyroscopes, such that the working modes of the platform system and the strapdown system are effectively unified, the use requirements of complete attitude motion and high reliability of the carrier can be met, and the test means and the data support can be provided for the multi-information fusion control of the platform system.

Description

technical field [0001] The invention relates to a hybrid inertial platform system, in particular to an inertial platform system adapted to the full-attitude maneuvering operation of the carrier and multi-information fusion control, which can be applied to ballistic missiles, cruise missiles, fighter jets, etc. that require full attitude, and belongs to inertial measurement technology field. Background technique [0002] On carriers that require large maneuverability, such as ballistic missiles or fighter jets, the gyroscopes of the high-precision inertial platform system currently mainly use liquid floating gyroscopes, hydrostatic liquid floating gyroscopes, three-float gyroscopes, and dynamic tuning gyroscopes. The platform frame structure It is a two-frame three-axis form or a three-frame four-axis form. [0003] In the platform scheme disclosed by China Aerospace Press "Inertial Devices", the platform all adopts 3 single-degree-of-freedom integral gyroscope schemes or 2 ...
