Orpheon is the first French multi-constellation network in France.
The geometric regularity of our layoutsThe Orphéon network has 220 stations in mainland France, all Full GNSS, i.e.: GPS, GLONASS, Galileo and BeiDou, as well as a historical presence in the French West Indies. The dense network of permanent stations is arranged regularly every 60 km. Each link in the Orphéon infrastructure has been designed to offer a high-precision RTK correction service available in all circumstances. Border areas are complemented by our partnership agreements within Europe.
A very regular presence, without compromise and without equivalent in France.
- The careful choice of layout for each of our 215 reference stations creates a linear and regular geometric mesh. Territory coverage is uniform wherever you are.In network corrections mode for a centimetric GNSS RTK receiver, the positioning accuracy is independent of the distance to the nearest physical network station.
With the Orphéon network, you work with identical precision throughout the territory thanks to a cell of several reference stations created around the user and the homogeneous distribution of the stations over all the areas covered, whatever your position.
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.
In single-station mode (agriculture), the distance from the nearest reference station is never more than 30 km.
A cell of several stations surrounding the user and regular and homogeneous layoutThe Orphéon network thus stands out significantly from its competitors who are multiplying the number of reference stations because of their disorderly location on the territory and whose coverage is losing homogeneity, sometimes leaving very large distances in the meshes of their network.

The Orpheon network: 15 years of presence in the West Indies
The West Indies have always been the subject of particular attention at Geodata Diffusion, it is in this region that the Full GNSS service was offered for the first time in preview
The coverage of the Orphéon network is reinforced at the borders thanks to the sharing of reference stations of our international network Hxgn SmartNet with :
Integration into a European network
To guarantee a continuous service of constant quality throughout the territory, we share the reference sites within the European network of our Hexagon group.
This European network allows us to integrate additional reference stations and extend the coverage of the Orphéon network for French customers. In this way, even near a border, it is possible to work in a network while being within an RTK cell (and no longer in extrapolated mode).
The highest availability rate on the market
The strength of the European network is to share infrastructures and the most qualified technical teams to guarantee identical control procedures over the entire coverage area, continuous and regular reinforced monitoring of all stations and the network. This international technical team from a major manufacturer is responsible for supervising all installations 24 hours a day, 365 days.
Increased productivity and quality of satellite positioningFull GNSS is the addition of the Galileo and BeiDou satellites to the GPS and GLONASS satellites, which allows you to significantly increase the number of satellites observed simultaneously by your GNSS antenna. With Full GNSS you work further and longer in wooded areas or bordered by buildings, where some satellites are hidden or even unusable by the equipment while maintaining a correct and precise geo-referenced position. Full GNSS also offers faster access to precise and more stable positioning thanks to the third frequency GPS and Galileo (L5) allowing easier resolution of phase ambiguities and rejection of multipaths.
The 3D control offer
This is access to the N-RTK Full GNSS correction network with centimeter precision (GPS, Glonass, Galileo, Beidou). Often used to control the accuracy of its measurements or even for areas where a mobile internet connection is not available for real time.
Mobile Internet access
To save you additional steps and expenses, we have forged close partnerships with the major French mobile operators SFR and Orange to provide you with SIM cards for mobile internet at the best conditions.
Network and subscription monitoringThe free Orpheon application gives you access from your smartphone to a large number of very practical and complementary features of your subscription or package.
