| Abstract: | Galileo system is a global, multi-mode satellite position and navigation system, which is developed and self-governed by Europe. The system can provide position service with high accuracy and high reliability, At the same time, it is completely controlled and managed by European Community, not by army. In this paper, the Satellite visuability,GDOP value, TDOP value, PDOP value, HDOP value, VDOP value in global scope have been simulated with the software GSSF V2.0 and analyzed. |
