Problems solved by technology

As the combined installation of the hemispherical resonator gyroscope is changed to a three-orthogonal-inclined installation, the existing measurement method is no longer applicable. Due to the influence of the earth's rotation angular velocity, there is a certain deviation when measuring the combination of star gyroscopes

Embodiment Construction

[0022] The method steps of the present invention will be further described below in conjunction with the drawings and embodiments.

[0023] Step 1, use the reference plane to flip the tooling to measure a single gyroscope

[0024] Such as figure 1 As shown, it is a schematic diagram of the reference plane turning tool used in the present invention,

[0025] Taking the bottom surface of the reference plane flipping tool as a reference, the gyroscope assembly with three orthogonal and one inclined gyroscopes is installed on the slope 22 of the reference plane flipping tool, so that a single gyro installed on the slope 22 is in a vertical state with the horizontal plane;

[0026] Step 2, measure the performance index of a single gyroscope

[0027] 1) The axis of the single gyro to be tested must be perpendicular to the horizontal plane;

[0028] 2) Measure the performance index of a single gyroscope installed on an inclined plane;

[0029] 3) Flip the datum plane Flip the two...

Abstract

The invention discloses an index system measurement method for a satellite hemispherical resonator gyro combination. The method comprises the steps of: utilizing a base level turning tooling to measure performance indexes of single gyro; using a triaxial rate turntable to measure the output data of the hemispherical resonator gyro combination; and calculating the setting angle deviation of gyros. The method provided by the invention can eliminate the influence of ground speed on calibrated error, avoids tedious calculation, solves the precision calibration problem of a satellite three-orthogonal one-oblique installed gyro combination, and improves the attitude control precision of an attitude control system.

Description

technical field [0001] The invention relates to satellite attitude control technology, in particular to satellite attitude control ground test technology, in particular to a hemispherical resonant gyro combination measurement method for satellites. Background technique [0002] The hemispherical resonant gyro combination is an important sensitive device of the satellite attitude and orbit control subsystem. It is used to sense the inertial angular velocity of the satellite star, output its component on the star coordinate system, and provide continuous three-axis inertial angular velocity for each working mode and flight stage of the satellite. information. The measurement method of the gyro combination is mainly divided into two levels, one is the measurement of the technical index of a single gyro, and the other is the measurement of the deflection angle of the installation position of the gyro in the combination. In the existing conventional gyro combination, the install...
