Product Introduction RLG-GD70A inertial navigation system is an inertial navigation system based on type 70 ring laser gyroscope and quartz flexible accelerometer. It can be combined with auxiliary equipment such as GNSS, altimeter, airspeed meter, etc., and can provide air carrier, ground carrier, etc. Navigation information such as speed, position, and attitude.
The Type 70 series inertial navigation system can be widely used in carrier platforms such as tanks, various types of armored vehicles, self-propelled artillery, rockets, various types of aircraft, drones, ships, automobiles, high-speed rail, unmanned vehicles, mobile satellite communication systems, and drilling. Flight control, attitude stabilization, weapon stabilization platform, positioning and orientation, etc.
