This gyro has 2 times the diameter and 3 times the weight of the one Leon Foucault used in 1851.
The flywheel is dynamically balanced. This technique is superior over static balancing and didn’t exist in 1851.
The bearings used in this gyro are high precision spindle bearings. Tolerance class P4S.
The original Foucault gyroscope is lost, only replicas exists. None of them are functional.

GPS Latitude: 48.21°.
Expected rotation per 10min: 1.864° at that given Latitude.
In the globe model you should see a clockwise rotation of the gyro on its z-axis.

Do gyroscopes really appear to drift over time due to the spin of the earth? Have you tested it for yourself?
