Abstract: Global navigation satellite systems play a significant role in the development of intelligent transport systems, where the estimation of the vehicle’s position is a key element. How-ever, in strongly constrained environments such as city centers, the definition of quality metrics and the assessment of positioning performances are challenges to be addressed. Due to the variability of different urban scenarios, the model-ing of the dynamics as well as the architecture of the posi-tioning platform, which might embed other sensors and aid-ing means to the GNSS unit, make it hard to define unam-biguous positioning metrics. Performance assessment through analytical models and simulators can be ineffective in terms of cost, complexity, and general validity and scala-bility of the results. This paper shows how a record and replay approach can be an efficient solution to grant fidelity to a realistic scenario. This work discusses advantages and disadvantages with emphasis on the case study of harsh scenarios. Such an approach requires proper data collec-tions that allow the replay phase to test the GNSS-based positioning terminals. This paper presents the results ob-tained on a set of field tests related to different scenarios, selected as representative for the key performance indica-tors assessment.
