The Eurofix system for example, can determine positions with an accuracy of 5 metres for 95 percent of the time. A problem that arises when using these differential satellite systems, is the bad reception quality of the satellite signals in areas where ‘shadowing’ occurs. These shadowing effects are caused by large obstacles, like the buildings in cities, blocking the propagation paths of the satellite signals. During the time these effects occur, satellite signals cannot be used for a reliable position determination. A solution to this problem is to combine differential satellite systems with some kind of backup system, which is able to give accurate position determinations during the time shadowing effects occur.
