Overview: Enhanced precise positioning is a key feature to enable advanced CCAM services where lane accuracy is needed to provide an accurate situational awareness to the vehicles. Although a combination of Global Navigation Satellite System (GNSS), Inertial Navigation Systems (INS) and vehicle sensors can satisfy most of the minimum requirements of different use cases, in some locations where satellites cannot be easily tracked, like urban or rugged areas, it could lead to inaccuracies of several meters and significant latencies.

5GCroCo has analyzed three positioning solutions to enhance vehicle’s location, 5G NR side-link, 3GPP GPS Real Time Kinematic (GNSS-RTK) and Ultra-WideBand (UWB); following the terminology described in TS 38.305, these three technologies illustrate RAT-dependent, hybrid and RAT-independent approaches, respectively. This webinar introduces the main characteristics, benefits and challenges of these three technologies in CCAM scenarios, as described on Deliverable D3.2 on “Intermediate E2E, MEC & Positioning Architecture”. Moreover, it presents experimental results of the 3GPP GNSS-RTK and UWB solutions, which have been demonstrated in 5GCroCo within the context of the Anticipated Cooperative Collision Avoidance (ACCA) Use Case in a highway and an urban scenario. The evaluation of the obtained results shows that both technologies can provide centimeter-level accurate positioning.
