State-of-the-Art and Development Trends of Inertial Navigation Systems Based on the Ring Laser Gyroscopes

The article summarizes and analyzes information on the batch-produced high-end inertial navigation systems. The market dynamics for the high-end inertial systems and gyro pickups over the past 10 years are given. The dominance of inertial systems based on the ring laser gyroscopes for the mid-term and autonomous navigation is shown. The prevailing design and technological solutions of modern ring laser gyroscopes are considered. The similarity of foreign devices due to the optico-physical circuit is noted. The key developers of laser inertial systems are identified. A trend towards the reduced weight and dimensional specifications, decreased cost and energy consumption of the ring laser gyroscopes while maintaining the required accuracy and resistance to the external influences is shown. © 2024, Technosphera Publishing House.
