Land RLG INS (Dubhe-L4)
This tactical-grade vehicular navigation system features RLG/FOG technology with quartz accelerometers in a ruggedized strapdown configuration. Providing continuous positioning through ZUPT and sensor fusion, it ensures operational capability in extreme conditions (-65° latitude to Arctic environments).
Deployment platforms include: Main battle tanks, self-propelled guns, IFVs, and unmanned systems.
Battlefield features:
1) Rapid alignment;
2) GNSS-denied navigation;
3) Extreme climate operation;
4) EMI-hardened reliability.
