No RTK correction source, no RTK transmision, no precision.


Precision Agriculture is the best way
to be profitable.


The right reason, why Precision Agriculture.



Our products

GPS Systems

It´s device, which provides and processes work with satellite signals on different levels of accuracy. Compatible with all top GPS manufacturers ( John Deer, Topcon, Trimble, AgLeader, RAVEN, Müller Elektronik, etc.).

RTK Modems

They provide the transfer the RTK correction signal from VRS or Permanent Base Station to the rovers in each agriculture machine where they are present.

Base Stations

Source of the RTK correction signal (NTRIP), which provides the precision, stability and effectivity for performance of the selected jobs on the selected field.


Online data monitoring of all processes, archiving and statistics analysing present and previous processes and jobs with , selected machine and field, focused on their parameters with respect to time.

About us

FONS s.r.o. has been working on the field of the HiTech technology of GPS navigations for more than 15 years.

Heading to the using of the GPS for agriculture FONS started with the closer cooperation with the manufacturer of Trimble GPS systems. That time FONS started to develop its own HiTech technology of RTK Network Solution with the focus for Precision Agriculture.

FONS was approached to become the authorized Topcon dealer for Czech Republic in 2013.

In 2014 company FONS performed during the Exhibition Techagro for the first time in the eastern Europe the autopilot directed with the precise RTK correction signal on the real outside exhibition area. In 2015 in Hannover - Germany during the Exhibition Agritechnica presented for the very first time the whole concept of RTK Network Solution for Precision Agriculture supporting all significant manufacturers of the GPS systems (John Deer, Topcon, Trimble, Agleader, Raven, Müller Elektronik, etc.). So the GPS systems can really reach their top precision, stability and effectivity .

By this action, the company FONS has been a significant player in the field of precision agriculture.
