High precision measurements of the Earth’s rotation rate made with ring laser gyroscopes are not only important for the Earth sciences, but are also relevant for fundamental physics tests, as they contain terms of general relativity, such as de Sitter and Lense Thirring effects and provide unique data to investigate Lorentz’s violations. Ring lasers ensure long-term continuous operation with record sensitivity. The limit to be reached for studying the fundamental physics of 1 part in 10^9 of the Earth’s rotation rate has already been demonstrated, and recent sensitivity study has shown that the ring laser shot noise limits is at least a factor 10 better than expected. The GINGER project is based on ring lasers array that is under construction at the underground Gran Sasso laboratories, as part of the UGGS underground geophysical observatory. Its status will be described.

Abstract
High precision measurements of the Earth’s rotation rate made with ring laser gyroscopes are not only important for the Earth sciences, but are also relevant for fundamental physics tests, as they contain terms of general relativity, such as de Sitter and Lense Thirring effects and provide unique data to investigate Lorentz’s violations. Ring lasers ensure long-term continuous operation with record sensitivity. The limit to be reached for studying the fundamental physics of 1 part in 10^9 of the Earth’s rotation rate has already been demonstrated, and recent sensitivity study has shown that the ring laser shot noise limits is at least a factor 10 better than expected. The GINGER project is based on ring lasers array that is under construction at the underground Gran Sasso laboratories, as part of the UGGS underground geophysical observatory.
