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).
Bathymetric measurements and missionsBy coupling your measuring instruments (echo-sounder, scanner, sonar, magnetometer, sensors) to a GNSS receiver, it is thus possible to geo-reference your measurements. By adding an inertial unit, it is possible to compensate for the movement of the boat to obtain even more precise results. These same corrections, provided in real time by the Orphéon network, also facilitate the processing of data or images. The professional reports generated are also of better quality for all your business applications:
- Bathymetry and topography
- Inspection and auscultation of water structures
- Monitoring of dredging and port developments
- Monitoring over time of the morphology of banks and deposits
- 3D modeling in and out of water
- Acoustic imaging
- Recognition of sedimentary facies
- Diagnosis of backgrounds and obstacles
- Study and construction of facilities (ports, banks, etc.)
- Current, swell, tide measurement
- Physico-chemical analyzes (conductivity, temperature, PH, oxygen, turbidity, chlorophyll)
In addition to the development of river transport, the versatility of water uses and the diversity of professions, the management of waterways and infrastructures reveals a naturally ecological dimension adapted to national economic needs.
Whether it’s hydroelectric developments or reservoirs dedicated to other uses such as agriculture, their significant land footprint and the potential risks they may represent. For the study, the development, the maintenance, the follow-up of the deposits but also the follow-up of the catchment areas upstream and downstream or even the monitoring of the phenomenon of aging of the works of art, the follow-up of aging. Depending on the nature, structure and classification of the structures concerned, various monitoring programs are put in place; either by regular inspection visits, or by the installation of permanent monitoring means.
Port ManagementThe management of a port requires precise and adapted solutions for: the study, the construction, the development, the maintenance, the positioning and the navigation aid.
Underwater equivalent to hypsometry or terrestrial topography. Bathymetric, or hydrographic, measurements establish maps that are generally produced to aid in the safety of surface or underwater navigation, and usually show underwater features, such as an ocean trench, or terrain such as contour lines (called depth contours or isobaths) and selected depths (soundings), and usually also to provide surface information for coastal navigation.
Oceanography, in the sense of the study of the coastal and offshore marine environment, aims to know the dynamics of the oceans, as well as the physico-chemical and environmental parameters governing this environment. The quality of the means of observation is therefore essential to carry out these studies on the entire water column: remote sensing, fixed measurement stations, on buoys or boats to better understand the functioning of the ocean-atmosphere, climate change, changes in the water cycle or sea level.
Renewable energies, offshore, oil & gas
Determine the nature of the funds, the potential obstacles to an infrastructure installation but also a continuous monitoring to observe the environmental impact, the state of the submerged installations.
Choosing a software solutionDepending on your business applications (Territory Analysis, Infrastructure Inspection, Surveillance), it will be necessary to control all of your sensors to store and process all of this information. This dedicated software and specifically adapted to these issues, will allow you to significantly save calculation time on your complex projects (digital dense surface 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.
