Which statement best describes a Ring-Laser Gyrocompass (RLG)?

A ring-laser gyrocompass uses ring-laser gyros to detect angular motion about the ship’s three axes, which lets it establish a stable heading relative to true north and provide attitude information. It senses pitch and roll (attitude) and the azimuth along with the rates of change of those angles (attitude rates). Those angular measurements form the core of an integrated navigation picture, where, when combined with other data, position and velocity can be computed along with the attitude, heading, and their rates. It is not an atmospheric pressure instrument, not a satellite-based system, and not a passive listening device.
