Abstract

Based on the application of Geometry Dilution of Precision (GDOP), 5 main aspects of GDOP are studied. It is concluded that different constellation parameters influence GDOP of different latitude. GDOP, PDOP and TDOP are not changed but HDOP and VDOP are changed by coordinate conversion. GDOP decreases along with the number of satellites, but the decreasing extent reduces too. The more a satellite contributes to GDOP, the more the positioning error it produces when it has fault. Using weighted GDOP reduces the positioning error effectively.
