Description

Technical field [0001] The present invention relates to a high-precision three-axis double redundant light source integrally FOG measurement setup, in particular a high reliability for the attitude control, high-precision three-axis fiber optic gyroscope measurement apparatus structure, belonging to an optical fiber gyro inertial measurement technical field. Background technique [0002] FOG means is based on all solid Sagnac effect of inertial instruments for measuring the angular rate vector, applied to the attitude control in the number of satellites, the satellite attitude control system is the key constituent elements. FOG primarily used to measure the three orthogonal axes with respect to the combination of the rotation angular velocity in inertial space, attitude measurement to provide attitude control information to achieve high accuracy and high stability. The main function of the fiber optic gyro is completed: measuring FOG combined triaxial angular velocity information...

Problems solved by technology

[0003] Due to different application environments and functional requirements, some satellites need to have higher requirements in some aspects, such as weight, volume and accuracy, and the common three-axis orthogonal gyroscope is only suitable for the distance of low orbit and high orbit. The optical fiber gyroscope measuring device for long-distance transmission is also applied in the existing technical solutions
