5G Positioning And Hybridization With GNSS Observations
Résumé
The present paper depicts the tests and experimentations that have been carried out to show how GNSS and 5G can be used to improve positioning performance. In this frame, the design made during the 5G-Champion project has led to a solution combining both positioning systems in different environments to show in which cases one solution is better than the others and in which cases they can be complementary. The experimentations show the interest of GNSS in open-sky and rural areas where 5G base stations will not be close to the user and will not be able to provide accurate positioning data. On the other extreme, in canyons and urban environments where buildings and multipath abundant can mask many satellites, the inclusion of 5G positioning data from stations that tend to be close to the user can improve the performance. At the end of this paper, a table summarizes the performance improvements, namely the accuracy and availability. Moreover, PPP solutions have been computed in order to see the benefits of PPP and 5G solutions combined.
