Abstract:	The modernized GPS and the Galileo system are designed to be interoperable and compatible making the use of measurements from both systems for single point positioning as easy as possible. Combination of both systems should be straight forward. Here we try to verify this statement by a bit-true GPS/Galileo signal simulator and a GPS/Galileo software receiver. We focus on lowbandwidth mass-market receivers, which are realized by proper configuration of the software receiver. The software receiver includes a novel BOC tracking algorithm and a sophisticated navigation Kalman filter. GPS C/A code signals and Galileo Open Service signals on L1 are processed for a static user and a dynamic user in an urban canyon. For the static user, we observe GPS/Galileo interference effects and improved positioning accuracy due to the improved geometry. For the dynamic user dramatic positioning accuracy and availability improvement is observed due to the Galileo system. Remarks for extending this single frequency receiver to a dual- or multi-frequency receiver are given at the end.
