Embodiment
[0049] Aiming at the problem of gyro faults, the present invention provides a fault diagnosis method for a gyro measurement system. Take the installation of 9 obliquely mounted gyroscopes on the satellite as an example, suppose the installation positions of gyroscopes G1~G9 are:
[0050] O g1 =[0.57735105,-0.43870300,0.68862577];
[0051] O g2 =[0.57735105,0.17672209,-0.79714181];
[0052] O g3 =[0.57735105,-0.37701591,-0.72424082];
[0053] O g4 =[0.57735105,0.60198402,0.55161672];
[0054] O g5 =[0.57735105,0.81571891,0.03561506];
[0055] O g6 =[0.57735105,-0.77870610,0.24552509];
[0056] O g7 =[0.57735105,0.10657412,0.80951079];
[0057] O g8 =[0.57735105,-0.75434397,-0.31245950];
[0058] O g9 =[0.57735105,0.64776985,-0.49705129].
[0059] (1) Analyze the top configuration
[0060] The angle relationship between the tops is shown in the table below. It can be seen from the table that the three groups of gyroscopes G1G3G5, G2G4G6, and G7G8G9 are orthogonal combinations, but the install...
