Aerospace RLG INS(Dubhe-A6)
Our advanced airborne optical INS combines precision gyros (FOG/RLG) and quartz accelerometers in strapdown/modulated configurations. The powerful navigation computer processes real-time data with flexible integration of GNSS, celestial, and other navigation sources.
Ideal for various UAVs and special aircraft,
it offers:
1) Robust ground/air alignment;
2) Configurable alignment methods;
3) Multi-sensor fusion capability;
4) Comprehensive health monitoring.
