Zusammenfassung:	A system and method for providing an accurate position for a GNSS device in an urban environment. The method includes determining a correction model based on differencing data and visibility data received from a plurality of sensors, estimating a current location of the GNSS device, deriving satellite parameters of a set of best visible satellites based at least on the determined correction model and the estimated current location, determining an accurate position of the GNSS device based on derived satellite parameters of the set of best visible satellites and a current location measurement provided by a GNSS receiver in the GNSS device, and setting a location of the GNSS device based on the accurate position.
