GeoMax Zenith40 GNSS Receiver Features

Superior Positioning

Struggling with canopy covers, or inaccurate results because of multipath signals are reduced due to the enhanced GeoMax Q-Lock Pro RTK which also reduces the time to fix. Also on board the Zenith40, Hexagon's TerraStar Precise Point Positioning (PPP) service that provides C-Pro correction data at centimeter level quality all around the globe.


Same as NovAtel and TerraStar, GeoMax is a full member of the renowned Swedish Hexagon Group. Using synergies, sharing components combined with the power to partner with premium suppliers, such as SATEL, and bundled with Hexagon's extensive manufacturing know-how enables GeoMax to offer products at highest performance and quality levels.
