Abstract
The importance of an accurate PNT (Position, Navigation, Timing) information is nowadays consolidated in the navigation field. Easy of use and robustness make Single Point Positioning (SPP) one of the most used techniques to compute navigation information, on the other hand, employing SPP may not lead to the achievement of the required performance, especially in challenging scenario. Different techniques or services could be used in order to achieve the target performance; in particular, the recent Galileo High Accuracy Service (HAS) could enhance the position accuracy. Several applications can benefit of HAS in particular geomatics, automotive, aviation, and maritime. This novel service provides corrections for orbits, code, phase, and satellite clock for Galileo and GPS (Global Positioning System) systems. Corrections are broadcast through the Galileo E6-B signal or other means (i.e., internet), and they have a global coverage. Even if HAS corrections are meant for the PPP (Precise Point Positioning) technique, in this study, they are applied to the SPP technique in order to assess the possible improvements in solution accuracy.Pubblicazioni consigliate
