Aerospace RLG INS(Dubhe-A20)
Designed for modern airborne platforms, this optical INS features FOG/RLG technology with quartz accelerometers in optimized strapdown architecture. The system's fusion engine integrates GNSS, celestial, and other navigation data while maintaining pure inertial capability.
Perfect for UAV operations
its highlights include:
1) Vibration-resistant alignment;
2) Flexible alignment options;
3) Expandable sensor integration;
4) Built-in system diagnostics.
