The first NRTK FULL GNSS network in France

This network allows us to market correction services to improve GPS positioning (centimetric level) mainly used by different companies for their professional missions:

  • Topography, GIS, network detection
  • Machine control
  • Agriculture
  • Drones, Robotics
  • Autonomous vehicles
  • Etc

Provide RTK GPS corrections

The Orphéon network is made up of nearly 220 observation stations, spread over the entire territory of mainland France and the West Indies.

All our stations form a large balanced RTK network that allows us to deliver RTK corrections to our many customers to increase the accuracy of their precision GPS. Our various services are marketed in the form of subscriptions or hourly packages.

The real strength of the Orpheon network

NRTK (Network Real Time Kinematic) comes from the use of several observation bases connected together in a network to optimize and model correction information on the covered area.

You receive corrections from a combination of multiple stations for greater stability and accuracy. There is only one hardware configuration to connect to the network anywhere in France, it is our server which is responsible for automatically establishing the cell of observation stations that suits you.

The positioning accuracy is independent of the distance to the nearest physical network station.


By providing the first centimetric Galileo full GNSS RTK GPS corrections for satellite positioning available in France, the Orpheon network demonstrates the strength of its commitment and the relevance of its technological choices in the daily service of its customers.

Everywhere in France our customers are not mistaken, every day more numerous, they confirm their confidence in us and we thank them for it.


All operations requiring centimeter accuracy are faster, more efficient, and more economical.


We offer a full range of services tailored to your needs.
