Land RLG INS | High-Precision Inertial Navigation for Ground Vehicles
Designed for demanding land and ground vehicle applications, this Ring Laser Gyroscope (RLG) INS integrates high-performance gyroscopes and precision accelerometers with advanced strapdown navigation algorithms. The system delivers accurate positioning, attitude, and motion data even in GNSS-denied, Arctic, or high-altitude environments, leveraging zero-velocity updates (ZUPT) and multi-sensor data fusion.
Ideal platforms include:
-
Armored vehicles and military land platforms
-
Unmanned ground vehicles (UGVs)
-
Special-purpose autonomous systems
Key Advantages:
-
Flexible and rapid initialization for quick deployment
-
Resilient navigation solutions under signal-denied conditions
-
Rugged operation in harsh environments with vibration, shock, and temperature extremes
-
Mission-critical reliability for long-duration operations
