Making a compact gyroscopic angular rate vector meter resistant to mechanical forces

The paper discusses a Compact Gyroscopic Angular Rate Vector Meter (CGARVM) developed and built by Kuznetsov research institute of applied mechanics based on a dynamically adjustable gyroscope with a rotor gas-lubricated spin-axis bearing system. The paper provides general technical data on the gyroscopic device (dimensions and mass parameters, measurement accuracy, the number of measuring axes, operational life, power consumption, etc.). The paper presents advantages and disadvantages of using the selected gyroscope (dynamically adjustable) as the sensing element. The advantages of this choice include the mean accuracy of measurements of this device while it has small mass and dimensions and long operational life. A disadvantage is the need to use special systems within gyroscopic devices (of the CGARVM type) designed to protect sensing elements against external mechanical loads, occurring when a spacecraft is being put into orbit by a launch vehicle. The paper sets forth key principles of assuring resistance to such loads...
