Laser gyro can be used to provide real-time heading, speed, altitude, attitude and other spatial position information for all types of aircraft and precision guided weapons, improve the aircraft's reliable flight time, and greatly improve the accuracy of precision guided weapons. Laser gyros can provide azimuth reference for maneuvering ballistic missiles and cruise missiles, enabling them to achieve rapid directional positioning and accurately hit targets. Ships, submarines and torpedoes can also be used to provide baseline data such as heading, speed and position. They can independently navigate in real time without relying on any external information. The combination of laser gyro and global positioning system (GPS) as the core components of precision navigation system is also widely used in nuclear submarines, aircraft, cruise missiles, intercontinental missiles and satellite guidance. This system has been tested many times.
In addition, the laser gyro can be used as a stable regulation system for tanks and infantry fighting vehicles to realize the self-perception of the car body state; it can also be used as an important part of the spacecraft attitude and orbit control system, and can also be used as an inertial guidance system for the launch vehicle. In other civilian fields, laser gyros can be installed on the telescope to provide real-time angular coordinate information. Ultra-large laser gyros can be used to observe seismic wave information, solid ground tidal effects and gravitational waves. It can be foreseen that with the improvement of laser gyro technology, its application scope will be more extensive, which will inevitably have a huge impact on future wars and daily life.
