Orpheon Network

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 of our stations form a large, balanced RTK network ideally distributed over the territory, allowing us to deliver individualized real-time RTK corrections to each of our users to increase the accuracy of their precision GPS positioning. Our various services are marketed in the form of subscriptions or hourly packages.

The real strength of the Orpheon network

The proposed NRTK (Network Real Time Kinematic) geolocation mode comes from the use of several observation bases connected together in a network to optimize the correction information individually for each user wherever he is on the territory and instantly .

Note also that only one configuration of your equipment is required to connect to the network everywhere in France, and it is then our server which is responsible for automatically establishing all the corrections specific to the station cell. observation of the place where you are and which suits you best.

Our strength: positioning accuracy does not depend on the distance to the nearest station or network antenna.


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.
