5G LEO
Full title: Coordinated 5G LEO-5G cellular positioning for improved safety functions in heavy vehicles
Abstract: Positioning is one of the building blocks of several safety features in Active Safety Systems (ADAS). At present, absolute positioning is done via GPS, which often suffers from problems with poor drawing in urban environments and tunnels. An alternative solution for absolute positioning is to use signals for cellular communication, which can provide similar performance to GPS, but is limited by the number of visible base stations and multipath in the propagation environment. The idea of this project is to build on the evolution of 5G systems that will introduce Low Earth Orbit (LEO) satellites for better communication coverage, as such non-terrestrial 5G networks (NTN) will be integrated together with the terrestrial ones. Our goal is to combine these NTN networks with the land-based 5G networks for accurate positioning of heavy vehicles. This bypasses the limitations of both GPS and land-based 5G positioning, which will ultimately increase traffic safety.
Traffic safety benefit: With precise positioning, safety functions can make more accurate decisions, resulting in improved traffic safety.
