Geo-hNAV™ is a ruggedized, fully-integrated hybrid dual-GPS-aided inertial navigation system which delivers consistent position and attitude measurement accuracy whether the platform is static or moving.
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.
Flexibility
Provides consistent level of measurement accuracy in static and in dynamic conditions
Multiple IMU configurations available with internal MEMS or external FOG/RLG IMUs
Multiple GPS configurations available with both civilian and SAASM receivers
High Navigation Performances
Centimeter level positioning with dual frequency RTK configuration
0.05° heading measurement accuracy both in low and high dynamic conditions (dependent on GPS baseline separation)
High navigation output rate (up to 125 Hz)
