Provide GPS correction servicesThe 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.
Real-time correctionsThe 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 networkN-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.
Corrections in post-processingPPK (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.
BenefitsIn 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.
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.
