| Question: |
Does anyone know how much g-force can affect the accuracy/reliability of a gyroscope?
Many thanks

| | G-force should not affect a gyroscope provided the gyroscope is designed correctly. The cages/gimbals needs to have good symmetry. If they are not then, the design/ manufacturing flaws will show up as unwanted precession as the G-forces increase. So in a sense g-forces can amplify the inaccuracies of the gyroscope. These inaccuracies are usually so small, time would be better spent improving other aspects of the gyroscope. It is not unusual for commercial/military gyroscopes to withstand 20G, 30G or more. Bearings also need to chosen carefully. I quick high G shock (e.g. being dropped) can damage the bearings badly. In some cases resulting in total failure of the gyroscope.

| | High g shock:
Can you suggest a suitable bearing system for a gyro under strong oscillating radical thrusts, while also vibrating heavily toward the plain of rotation (bouncing) between two containing walls? Yeah, I know, but what would last longest? I will pay attention to whatever you have to say if anything.
Glenn,
