Precise navigation without magnetic heading limitations

Sensor fusion algorithms

True heading without motion


Dual GNSS antennas provide accurate, true-north-referenced heading at standstill and during low-speed operation, without relying on magnetic measurements or requiring the platform to move.

vibration

Centimeter-level RTK positioning


Advanced sensor fusion and RTK corrections deliver centimeter-level positioning, precise orientation and reliable heave data for applications requiring consistently accurate navigation.

rugged housing

Rugged and ready to integrate


The compact aluminum enclosure provides IP68 protection and MIL-STD-202-tested durability. Multiple interfaces support straightforward integration into vessels, vehicles and other outdoor platforms.
