Orpheon on demand 

For your short-term work or for your short stays in France, we offer a series of GPS correction services.

Ideal when you know a mission is coming and you want to make sure everything will be ready on D-Day.

In order to offer offers perfectly adapted to the needs of users, we have designed several one-time subscription formulas. These various services are marketed exclusively on our website in the form of subscriptions or hourly packages specifically adapted to short periods.

Services offered online

RTK subscriptions by day or by month

We propose a daily or monthly license for the duration of your mission in France.

These temporary subscriptions give access to unlimited “real-time” correction services to N-RTK Full GNSS repeatable centimetric network corrections (GPS + Glonass + Galileo + BeiDou). It is thus possible to choose your period according to your real need, and then benefit from adjusted rates.


45,00 € HT

Promotional offer until April 30, 2024

450,00 € HT / month

395.00 € HT / month

5-hour packages to be used over 1 month

We propose an hourly package to be used over 1 month to meet your very short assignments in France.

These hourly packages give access to real-time RTK correction services from the Full GNSS network or to an online post-processing solution and Rinex data from the network.

And of course our full range of services adapted to your needs (Quote upon request)

Discover each of these high-precision GPS correction services in the form of annual subscriptions or hourly packages.

Each of our offers is flexible to adapt to your real needs.


Real-time corrections

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 NRTK (Network Real Time Kinematic) comes from the use of several bases of observations to optimize and model the information of corrections on the covered area.

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.


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 short-term obligations.

Commissioning of the services ordered within 24 hours (excluding weekends and public holidays) after receipt of the subscription form correctly completed and signed.

The network has been thought out and designed according to the rules of the art, it is constantly monitored and checked regularly. (The network-Orpheon).

Everything has been thought out to allow you to benefit from increased productivity.

The Orphéon network is made up of nearly 220 observation stations, spread throughout the 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.

With the Orpheon network, you work with identical precision throughout the territory thanks to a uniform distribution of stations in metropolitan France and the West Indies. Whatever your position, the distance from the nearest reference station is never more than 30 km.

100% Galileo and BeiDou correction services in addition to GPS and GLONASS:

  • more satellites (+22 Galileo)
  • faster fixing,
  • more measurement stability,
  • more availability,
  • better positioning
  • fewer multipaths

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 full 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 results.

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.
