RTK drones
A large number of drones now incorporate precision GPS which allows results to be obtained with centimeter precision, making it an effective tool for surveyors.
The use of a fixed base to obtain precise positioning in real time can present some heaviness, such as ensuring its precise geo-referencing so that the entire site is well set up or its monitoring.
Work with a national network
Using corrections from a network allows you to concentrate on the essentials of your mission and your site. It gives you more flexibility with the possibility of chaining distant missions since the service is available everywhere in France.
The network makes your life easier: no base to transport, install, set up or monitor.
Drones now use the Orpheon network
Photogrammetry
Photogrammetry makes it possible to reconstruct surfaces from photographs acquired from different points of view using the parallax obtained between these images (principle of human stereoscopic vision). Digital photography makes it possible to correlate the geometry of the images and their acquisition in order to more precisely model a 3D copy of the photographed scene. The quality of each shot, the quality of the sensor, the brightness, the optical distortion, the ability to position the shots between them will influence the quality of this 3D modeling. It is therefore important that each shot is positioned preciselyVaried missions
Need for Precision
Savings and increased productivity
With the geo-referencing of the images made during the shooting thanks to the on-board precision GPS, the working time of digital production is considerably reduced. In a single operation, the data is thus recorded and calibrated in the national reference system. The integration of RTK GPS and latest-generation inertial units combined with GNSS corrections generated via the Orpheon network allows rapid implementation and simplified deployment, since they eliminate the need for a second GNSS receiver (basic ) nationwide. These same corrections, provided by the Orphéon network, also facilitate the processing of data or images in real time or in post-processing. The professional reports generated are thus of better quality.
Precision in all areas
The precision obtained makes it possible to work in a very large number of applications, such as:
- Architecture
- Construction, Construction
- Construction, inspection of works
- Volume calculation (earthworks)
- Thermometry
- Ortho photography
- Photogrammetry
- Multispectral imaging
- 3D modeling
- Bathymetry and maritime works
- Network management or implementation
- Urban heritage management
- Archeology
- Geology
- Petroleum and energy sector (high voltage line survey)
- Transportation (Railway)
- Forest
- Agronomy
- Precision farming
- police work
Choosing a software solution
Depending on your business applications (territory analysis, infrastructure inspection, surveillance), it will be necessary to store and process all of this information. This software dedicated and specifically adapted to the problems of Drones will allow you to significantly save calculation time on your complex projects (Dense surface digital models MNS, digital terrain models DTM, detection of changes etc.)
Our distributors are at your disposal to support you and offer you the solution best suited to your needs, do not hesitate to contact them.
Essential training
The use of an aerial drone is very much regulated by strict legislation that few people know about. This legislation makes it possible to regulate the use of drones in the airspace to avoid serious incidents & accidents, while defining specific rules according to the categories to which they belong. It is therefore essential to have the theoretical ULM pilot certificate (with the DGAC) and a Declaration of skill level (DNC) recognized by the DGAC. He will therefore be able to practice the profession of drone remote pilot professionally.

Downloading RINEX Files for Post Processing
Geodata offers, via an Internet connection to access a Web interface, the downloading of RINEX files necessary to improve its positioning by differential methods in deferred time (post processing).
Depending on the type of measurements carried out, fixed or mobile, several post-processing solutions can then be envisaged with respect to a physical permanent station or else with respect to a virtual station created from several physical stations.
compared to physical permanent stations
- PPK method: Kenematic post processing for mobile rover
- PPS method: Post processing Static for fixed rover
relative to a virtual station
- N-PPK method: Network Post processing Kenematic for mobile rover
- N-PPK method: Network Post processing Kenematic for stationary rover
We offer an offer in the form of different Hourly Packages* adapted to your different needs. (*valid for 12 months from the date of subscription).
Do not hesitate to contact us for any additional information.
