Orpheon network

The first NRTK FULL GNSS network in France

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.

This network allows us to market correction services to improve GPS positioning (centimetric level).

The real strength of the Orpheon network

You receive corrections from a combination of multiple surrounding stations for more stability in your measurements and accuracy in practice.

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



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


We offer a full range of services as of subscriptions or hourly packages tailored to your needs. (Click on the links)
