Ring laser gyro
Ring laser gyro A Ring Laser Gyro is a type of inertial measurement instrument used to measure angular velocity. It uses lasers to measure the rotation of an object, providing extremely accurate readings.

The Ring Laser Gyroscope (RLG) is a high-precision navigation device that utilizes lasers to measure an object’s rotation. It consists of two laser rings arranged perpendicularly to each other. In operation, lasers are activated and reflected within these rings at equal angles. The movement of the lasers is captured by a detection system. The rings are considered stable when the lasers move in the same direction; however, if they move in opposite directions, it indicates that the object is rotating.
The RLG stands out for its safety, reliability, and accuracy in navigation applications. It is specifically engineered to detect minor variations in angular velocity, allowing for precise measurements of position and orientation. This precision makes it especially suitable for high-accuracy navigation applications, such as flight control, robotic orientation, mechanical fault detection, and underground space orientation.
Furthermore, the RLG presents a viable alternative to conventional navigation systems, like Global Positioning System (GPS) devices, which can be susceptible to electromagnetic interference. As a result, RLGs are increasingly being employed in critical applications, including the navigation of ships, aircraft, and Unmanned Aerial Vehicles (UAVs). Their robustness and precision in various environmental conditions make them an essential component in modern navigational technology.
