The Effect of Galileo on Carrier Phase Ambiguity Resolution

and is continuing his studies, towards a Ph.D. in Geomatics Engineering, in the field of positioning of navigation at the University of Calgary. In order to achieve the highest level of positioning accuracy using GPS, one must first determine the carrier phase integer ambiguities. This will also be true with the Global Navigation Satellite System (GNSS) proposed by the European Union, Galileo. This paper discusses the effect of the proposed satellite system, GPS, and an integrated solution of the two systems on ambiguity resolution in kinematic mode. This paper will examine the effectiveness of ambiguity resolution with Galileo, GPS, and a combined solution. The addition of the Galileo constellation will increase the efficiency and reliability of ambiguity resolution when combined with GPS. The addition of 30 satellites transmitting with L-Band frequencies will decrease the time required for a user to wait before determining the correct integer ambiguities and therefore decrease the time before achieving the best possible position accuracy.
