Description
Sagnac Gyroscopes attached to the Earth surface are sensitive to the gravitomagnetic fields, and in principle the confrontation with independent measurements of the Earth rotation rate gives the possibility to measure the Lense Thirring effect without the necessity to map the gravitational field, and independently from the space measurements. It has been also pointed out that this kind of test provides accurate measurement of the angular moment of the planet, this property can be used in the future to investigate the existence of near by rotating Dark Matter. This kind of apparatus id highly multidisciplinary since it provides important data for geophysics and geodesy. Ring laser gyros are at present the most powerful Sagnac gyros, the results of the prototype GINGERINO are discussed.
