Global navigation satellite systems (GNSS) like GPS or Galileo have entered the market and daily life. Since GNSS are in principle line-of-sight system they work best in open sky environments. When the user enters a building, the line of sight is often blocked and the signals are strongly attenuated, subject to multipath effects or even totally blocked. In this thesis, several alternative positioning techniques have been analyzed and tested. Finally, the solutions are integrated into a short user trajectory, which is used as input to aid a GNSS software receiver.The system has been evaluated in a mixed indoor and outdoor environment.
