Abstract

The invention discloses a digital self-adaption universal combined gyroscope. The input/output port of a preferable satellite processor thereof is connected with the input/output port of a corresponding digital self-adaption gyroscope; the data output port of the digital self-adaption gyroscope is connected with the input port of the preferable digital self-adaption gyroscope; the data output port of the preferable digital self-adaption gyroscope is connected with the input port of a data fusion and Kalman filter; the output port of the data fusion and Kalman filter is connected with the input port of an output data controller; the input/output port of an inertial gyroscope is connected with the input/output port of the data fusion and Kalman filter; and the data output port of the inertial gyroscope is connected with the data input/ output port of the inertial gyroscope of the data controller. The invention combines the digital self-adaption gyroscope with the inertial gyroscope into the digital self-adaption universal combined gyroscope, and the two gyroscopes fully perform respective advantages and complement defects.

Description

technical field [0001] The invention relates to an adaptive gyroscope, in particular to a digital adaptive universal combined gyroscope. Background technique [0002] Traditional inertial gyroscopes include electromechanical inertial gyroscopes and fiber optic (laser) gyroscopes, which are based on the principle of conservation of angular momentum of high-speed rotating mass bodies. When the rotational speed is large enough, high-speed rotating mass bodies maintain a constant direction. It has autonomous work It has strong ability and is not affected by the environment, but it has the disadvantages of large zero drift, large attitude angle error, and inability to adapt to the horizontal coordinate system. The Chinese patent No. 200610096130.5 discloses a digital adaptive gyroscope. The working principle of this digital adaptive gyroscope is to use at least three small antennas and a multi-channel receiver to receive signals from at least four global navigation and positionin...
