BELGM50A High-Performance Marine Laser Gyro Inertial Navigation System for USV/AUV
This laser gyro-based inertial navigation system integrates strapdown technology and three-axis RLG sensors, specifically designed for unmanned surface vessels (USV) and autonomous underwater vehicles (AUV). With quartz accelerometers achieving ±0.01mg bias stability, it provides continuous positioning in GPS-denied environments. The modular design supports plug-and-play integration with sonar/DVL systems. Certified for marine survey and underwater pipeline inspection applications.
