GeoMax Zenith40


Zenith40 is the true flagship of the GeoMax GNSS receivers. Equipped with NovAtel`s latest, cutting-edge measurement engine and supporting fast converging Precise Point Positioning (PPP), this antenna provides a highest level of technology and meets the toughest MIL standards.

Zenith40 assures a workflow tailored to your needs thanks to the user-centered X-PAD Ultimate field software or the flexibility to run your own software on any field controller. The combination of all this in a GNSS smart-antenna creates an industry leading solution.

Package includes:

  • GeoMax Zenith 40 GNSS Receiver
  • GPS, GLONASS, BeiDou, Galileo & QZSS
  • ZBA201 Li-ion Battery
  • ZCH201 Charger for Li-ion Battery
  • GEV192 AC/DC Adapter GK112
  • ZRA101, Gainflex UHF Antenna (Frequency Range 400-473 MHz)
  • FZ-B2 Panasonic Tablet
  • Full X-Pad Ultimate Software
  • Zenith40 Accessory Kit: Case, Micro SD Card & USB
  • ZPC200 Telescope Carbon Fibre and Aluminium pole ZHR200, Pole Bracket for Controller

X-Pad Software:

GeoMax X-PAD field software is available in two tailored versions: One for surveyors and one for construction professionals supporting Windows and Android operating systems.

Due to the close cooperation with key-users all around the world, X-PAD Ultimate is continuously kept up-to-date and convinces due to its perfect balance between clear structure, straight forward workflows and high functionality.
The GeoMax software offering is completed by X-PAD Fusion, a fully featured office software that even enables automatic point cloud registrations.

X-PAD Fusion has the versatility and flexibility to fuse all data types from both GeoMax sensors and other 3rd party sources such as drones. The data is then compiled in one database which eliminates the risk of data loss as well as the need for time consuming data conversions.
