Cautions

Gyroscope should be avoided by impact, knock;
Gyroscopes with the same jitter frequency should be avoided in the same inertial navigation equipment;
Pay attention to the use of spring pad when installing the gyroscope. It is recommended to use M4hex socket screw with grade 9 (including) or above, and the recommended torque value is 2.5NM.
