Following the participation of our teams in the exhibition of the association of Mayors of Ile de France and the presentation of the new E-Nails service, discover more precisely the advantages of this new and unique geolocation solution, developed within RICE, the research center of GRTgaz.Precision geolocation: a real challenge in urban environments|A first phase of deployment in France and the United StatesIn France, 16,000 accidents are recorded each year on all the networks, which are a major source of nuisance for local residents and city users. It is therefore essential today to know the precise positions of buried networks, gas, water, electricity, telecom, to carry out repair or development work while minimizing the risks.
The geolocation of the networks is possible thanks to the use of the GNSS network (Global Navigation Satellite Systems) which has the characteristic of being sensitive to the obstacles present between the receiving terminal and the satellites. In urban areas, the more or less dense constructions interfere with the signals, making precise geolocation impossible.
RICE is developing a precision geolocation solution, E-Nails, based on UWB (Ultra Wildeband) technology. Transmitters are strategically placed at certain locations in the urban environment. The radio waves then allow triangulation and calculation of an exact dynamic position of a receiver located in the urban canyon, the area where the E-Nails are located.
The accuracy of the position is available at any time and the network operator can use an augmented reality application to locate his network or that of other operators. The operations are reliable and the georeferencing data can be fed into a geospatial database in parallel. A progressive deployment of this service would bring gains in terms of safety, time and quality for the whole ecosystem present in the urban environment.|The project currently has a unique demonstrator located on the RICE site in Villeneuve la Garenne that can be visited. The appeal of this new service is confirmed with the first two communities to be equipped next fall in France and the United States. These first pilots will allow RICE and its partners to improve the calculation algorithms and to refine the positions of the E-Nails in service as well as their position in the public space. This feedback will help adjust the design and production of the transmitters to ensure high quality accuracy.
The interest of this service lies in the applications of E-Nails, which cannot be limited to network operators. This new service has the ambition to bring in the future a real added value around the uses linked to the autonomous vehicle sector and soft mobility, tourism and heritage but also urban planning, so many sectors with multiple challenges and issues.
