The first NRTK FULL GNSS network in France
Created in 2004, has become a major player in GNSS satellite positioning in France. Pioneer in the implementation of the 1st permanent network of Full GNSS precision augmentation on the national territory, the company today covers a large number of applications through a large network of authorized distribution partners for all brands of receivers GNSS.
This network allows us to market correction services to improve GPS positioning (centimetric level) mainly used by different companies for their professional missions:
- Surveying, 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 that allows us to deliver centimeter 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.
Accuracy and availability
Thanks to its precision and the availability of its RTK GPS corrections, the Orpheon network offers increased productivity to all of its users in the fields of topography, construction, 3D digitization, machine control, precision agriculture and bathymetry, but also for new applications concerning autonomous vehicles, drones (UAV) and connected objects (IOT and M2M).
Géodata Diffusion continues to develop the quality of its services through personalized support, responsive technical assistance and continuous improvement of its infrastructures. Our objective is to offer customers a secure and innovative service, guaranteeing them a high and constant utilization rate wherever they are, throughout the territory.
Network modernization
In 2017 Geodata modernized the Orphéon network, updating some of the reference stations and replacing the oldest ones.
Since September 7, 2017, all the reference stations, the infrastructure and the correction calculation software allow us to deliver Full GNSS corrections: GPS + GLONASS + Galileo + BeiDou.
Orphéon becomes the first Full GNSS RTK network in France
By providing the first RTK Galileo corrections available in France, the Orphéon network demonstrates the strength of its commitment and the relevance of its technological choices in the daily service of its customers.
Our customers are not mistaken, every day more numerous, they confirm their confidence in us and we thank them.
50% more satellites
The addition of the Galileo and BeiDou satellites to the GPS and GLONASS satellites significantly increases the number of satellites that can be observed simultaneously by a GNSS antenna.
This compatibility is already valid for our new RINEX Post-processing & Download online services.
The addition of the GALILEO and BeiDou constellations thanks to the Orphéon network is not a simple gadget, but the assurance of better daily productivity in the field.
In fact, you can now permanently count on the constant availability of at least 6 additional satellites to bring you real advantages:
Improved positioning quality
- More satellites available to calculate its position
- Precise positioning even in difficult environments (urban canyons for example or under a canopy)
- Improved positioning reliability
- Shorter fixing time
We share the same requirement !
Géodata Diffusion continues to develop the quality of its services through personalized support, responsive technical assistance and continuous improvement of its infrastructures. Our objective is to offer customers a secure and innovative service, guaranteeing them a high and constant utilization rate wherever they are, throughout the territory.
Integration into a large European network
By integrating the Hexagon Group in 2014, the Orphéon network joined the largest network of reference stations within the first operational European NRTK network covering many countries.
On the strength of its international experience and its expertise in real-time positioning, the Hexagon group, within its various companies, intends to offer the most uniform and extensive real-time positioning service with centimetric precision.
To guarantee a continuous service of constant quality throughout the territory, we share the reference sites within the European network of our Hexagon AB 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).
This coverage is enhanced at borders by sharing reference stations from our international Hxgn SmartNet network with:
- Belgium
- Luxembourg
- Germany
- Swiss
- Italy
- Spain
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 the installations 24/365.

2- Address new innovation sectors
With the development of technologies and the emergence of the Internet of Things (IoT: Internet Of Things) allowing them to communicate, it became clear that we now needed to locate these objects with precision.
Some of the connected objects are fixed and do not change place, but a very large number of these objects accompany us in our movements or are simply in motion.
It then becomes very interesting, even essential, to be able, at any time or a posteriori, to precisely locate or materialize their position or their movements.
3- Provide high-level technical support
4- Ensure the complete and proactive maintenance of the network
Geodata Diffusion is an independent entity of the Hexagon group.

By joining the Hexagon group in 2014, the Orphéon network joins a vast network of reference stations within the first operational European NRTK network operating in 25 countries, including 18 in Europe. With its international experience and expertise in real-time positioning, the Hexagon group, within its various companies, intends to offer the most consistent and extensive real-time positioning service with centimeter precision.
This secure infrastructure, set up and managed by the Hexagon group, allows the pooling of resources, the management of which is centralized. It also allows to organize a service available 24/7 and to offer one of the highest availability rates on the market.
Increasing real-time positioning accuracy has become an issue and a critical requirement for high-growth areas such as autonomous navigation and precision agriculture. https://reseau-orpheon.fr/wp-content/uploads/2021/03/Global-Coverage.png This network is used daily by thousands of professional subscribers. Major groups and research centers therefore trust our network for their various applications and can benefit from Hexagon’s expertise. The service is marketed under the HxGN SmartNet brand
