The Premium Orpheon offer
These subscriptions give access to unlimited Real-Time correction services in the NRTK Full GNSS centimetric repeatable GPS + Glonass + Galileo + BeiDou network.
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 monitoring
The free Orpheon application gives you access from your smartphone to a large number of very practical and complementary features of your subscription or package.
Receive your invoices directly
You now have the possibility of receiving your Geodata Diffusion invoices in electronic format for all the services subscribed to. When you choose the electronic invoice option, you agree that your company will no longer receive paper invoices from us.
In your professional practice, you can count on the knowledge, the know-how and the centimetric precision of the Orphéon network to meet your missions and your obligations.
The network has been thought out and designed according to the rules of the art, it is constantly monitored and checked regularly. (Le réseau-Orphéon).
Everything has been thought out to allow you to benefit from increased productivity.
RTK precision positioning allows you to geo-reference your measurements simply and confidently in the national reference system in real time to save production time. Or even as a control tool thanks to the post-processing available online.
A regular mesh and a reinforced infrastructure for you to secure data transfer, for greater reliability and repeatability on a daily basis.
We have developed a complete range of high-end services so that you can choose according to your real need.
The availability of the service gives the possibility to work from day to night, in foggy weather etc. by focusing their attention on the GPS guidance tool and no longer on driving for an always impeccable result
Provide GPS correction services
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 network that allows us to provide our many customers with RTK and PPK corrections to increase the accuracy of their GPS.
Our various services are marketed in the form of subscriptions or hourly packages.
The RTK (Real Time Kinematic) is a device for transmitting real-time correction data from an observation base to mobile GPS through radio communication or via an internet connection.
The mobile will then integrate this information into its positioning calculation to gain precision.
The real strength of the Orpheon network
N-RTK (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.
- 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.
The data from this network of observation stations is collected in real time on a centralized server. Mobiles connect to the server via mobile internet to get their corrections information.
Corrections in post-processing
PPK (Post Processing Kinematic) to post-process your positioning data with observation data from an observation station.
Raw positioning data (without corrections) is stored in the GPS in Rinex format along with satellite observations such as satellite ID, frequency (L1/L2/L5, etc.), constellation, pseudorange, carrier phase, Doppler and signal-to-noise ratios.
RINEX (Receiver Independent Exchange Format) as its name suggests is a standardized format for storing positioning and observation data independent of the brand of the receiver and thus allowing post-processing of this data afterwards to obtain corrected positions much more precise.
Increased productivity and quality of satellite positioning
Full 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.
