Geo-hNAV

Rugged Hybrid Dual-GPS INS

Geo-hNAV™ is a rugged, hybrid dual-GPS-aided inertial navigation system which delivers consistent position and attitude measurement accuracy whether the platform is static or moving. The Geo-hNAV combines the best features of the Geo-iNAV inertial navigation system with the Geo-Pointer dual-antenna heading system. For stationary or slowly moving platforms, precise heading is derived from GPS measurements using two GPS antennas rigidly mounted on the platform, separated by a typical distance of 1 to 3 meters. In dynamic conditions, the combination of GPS and IMU provides enhanced position, velocity and attitude measurements.
