Aerospace FOG INS(Merak-A03)
Delivering exceptional navigation performance, this optical INS employs FOG/RLG gyros and quartz accelerometers in strapdown configuration. The real-time fusion center combines inertial data with GNSS, celestial and other sources.
Key advantages for UAV applications:
1) Reliable ground/air alignment;
2) Multiple alignment mode selection;
3) Scalable navigation augmentation;
4) Continuous system monitoring.
