Aldebaran FOG INS-GNSS

Aldebaran ALD-NS3500S is a rugged, tactical-grade Fiber Optic Gyro (FOG) based Inertial Navigation System with an integrated multi-frequency, multi-constellation GNSS receiver, delivering dependable position, velocity and attitude data across airborne, land and naval platforms.

How Aldebaran Processes Sensor Data

Sensor inputs are fused in real time through Aeron's proprietary Extended Kalman Filter to deliver stable navigation, attitude and heading estimates.
