Aerospace FOG INS(Merak-A05)
The airborne optical gyro inertial navigation system uses optical gyroscopes and quartz accelerometers as core sensors, employing strapdown or modulation technology systems. It operates advanced navigation software at high speeds internally, calculating and outputting navigation information in real-time. This series of products can integrate navigation information from satellites, astronomy, altimeters, radio, vision, etc., according to user needs, supporting pure inertial and multi-source information fusion working modes, providing users with comprehensive navigation information for the carrier.
Applications: UAVs and special aircraft.
Capabilities:
1) Ground/air alignment;
2) Alignment mode switching;
3) Sensor fusion;
4) Fault detection.
