Abstract

The paper illustrates satellite coverage and PDOP values for a simulated combined GPS/Galileo system. The designed GPS satellite constellation and the planned Galileo satellite constellation are presented. The combined system is simulated and the number of visible satellites and PDOP values are estimated at 4140 points aruond the earth. The simulation that is carried out with a 15 degrees cut-off angle is repeated every 10 minutes for 72 hours. The simulation shows that mean PDOP values are improved significantly when using a combined system compared to using only GPS.
