Aerospace RLG INS(Dubhe-A1)
The airborne optical gyro INS utilizes FOG/RLG gyroscopes and quartz accelerometers as core sensors, adopting strapdown or modulated architecture. Its high-speed navigation computer runs advanced algorithms to provide real-time navigation solutions. The system supports multiple operational modes including pure inertial and multi-source fusion (GNSS, celestial, altimeter, radio, and vision), delivering complete navigation parameters.
Applications include fixed-wing UAVs, rotary-wing UAVs, and special aircraft.
Key features:
1) Ground sway base/airborne alignment capability;
2) Switchable alignment modes (self/transfer/moving base);
3) Multi-source navigation fusion;
4) Fault detection and alarm functions.
