Provide RTK GPS correctionsThe Orphéon network is made up of nearly 220 observation stations, spread over the entire territory of metropolitan France and the West Indies. All of our stations form a large balanced RTK network that allows us to deliver centimeter RTK corrections to our many customers to increase the accuracy of their precision GPS. Our various services are marketed in the form of subscriptions or hourly packages.
Accuracy and availabilityThanks to its precision and the availability of its RTK GPS corrections, the Orpheon network offers increased productivity to all of its users in the fields of topography, construction, 3D digitization, machine control, precision agriculture and bathymetry, but also for new applications concerning autonomous vehicles, drones (UAV) and connected objects (IOT and M2M). Géodata Diffusion continues to develop the quality of its services through personalized support, responsive technical assistance and continuous improvement of its infrastructures. Our objective is to offer customers a secure and innovative service, guaranteeing them a high and constant utilization rate wherever they are, throughout the territory.
The natural position provided by a GPS alone, gives a good idea of where it is within a few meters, but is not precise enough to allow precision work. It requires correction so that its precision is increased and usable in agricultural work, topography, machine guidance or in many other fields of application (see).
Examples of machine control systems
Shovel excavation system
Two GPS / GNSS antennas are installed on the excavator turret in order to obtain its position, orientation and roll.
An inclinometer then makes it possible to determine the pitch (2-axis inclinometer to have redundancy on the measurement of the roll) and the position of the axis of rotation with the arrow. Angle measurement sensors on the boom, arm and bucket (inclinometers, cylinder extensometers, etc.) then make it possible to determine the position or even the orientation of the bucket, including underwater. In this way, it becomes possible:
- To lay pipes by digging trenches at the desired position and depth while managing slopes.
- To carry out leveling work (installation of embankments or platforms with the right slope(s).
- Manage height alarms under power lines and/or bridges.
System for bulldozer and graderIn order to determine the position and orientation (tilt and heading) of the blade, two GPS / GNSS antennas are mounted. Another solution is to mount a single GPS / GNSS antenna, coupled with a more or less complete attitude unit (from the simple roll or slope sensor to the measurement of the 3 angles of the blade) installed on the blade. From there, the hydraulics of the machine can be controlled so that the blade goes up and down automatically to maintain the correct slope when advancing the machine.
System for compactor
A GPS / GNSS antenna makes it possible to locate the compactor, a compaction sensor making it possible to detect anomalies in the settlement of the ground so that a supply of materials and a recompaction can be carried out.
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. (The network-Orpheon).
Everything has been thought out to allow you to benefit from increased productivity.
