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 intothe 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 have strong autonomous work capabilities and are not affected by the environment. However, they have large zero point drift and large attitude angle errors. Can not be adaptive and other shortcomings. 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 positioning satellites and Data, using the phase difference between the arrival of each navigation satellite to the three small antennas and the multi-channel receiver and the relative coordinates of the three small antennas, the headin...
