Statistical analysis of different low cost GPS receivers for indoor and outdoor positioning

The greater part of modern low-cost GNSS receivers are able to guarantee a fair positioning performance almost everywhere: difficult environments as indoor and urban canyons are also considered. The aim of this work is to investigate the effective potentialities of this kind of receivers, in particular in static and kinematic positioning using post-processing techniques. The high number of GPS permanent stations and the continuous increase of the number of GNSS multi-constellation permanent stations, will give a good opportunity to improve accuracy and precision levels.
