Services offered online

France Coverage
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.
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.

Europe Coverage
Benefit from 20 countries with a single subscription
RTK subscriptions for one month
We offer you the option of subscribing to a monthly license for the duration of your mission in Europe in the following countries:
Austria, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom
These temporary subscriptions provide access to unlimited “real-time” correction services for repeatable centimeter-level N-RTK Full GNSS network corrections (GPS + Glonass + Galileo + BeiDou). It is therefore possible to choose your period based on your actual needs, and then benefit from adjusted rates.
10-hour packages to be used over 1 month
We offer you the option of subscribing to an hourly package to be used over 1 month to fulfill your very short assignments in Euroe.
These hourly packages provide access to the RTK real-time correction services of the Full GNSS network or to an online post-processing solution and the 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.
RTK
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.
PPK
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.

Advantages
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.
