摘要：
Galileo is a global navigation satellites system initiatively launched by the European Union and the European Space Agency. This paper carried out initial assessment on observation data quality, single point positioning and precise single point positioning performance of Galileo system based on a large number of measured data obtained from the MGEX. The assessment results show that: the Galileo system has a small number of navigation satellites and cannot provide all day long navigation at present. The pseudo range multipath of Galileo is in decimeter-level variation, the multipath effect of E5 band signal is the least, while the multipath effect of E5b band signal is the most serious. Normally, the horizontal and vertical accuracies of Galileo SPP are better than 5 m and 10 m respectively. In general, the horizontal and vertical accuracies of Galileo Kinematic-PPP are better than 5 dm and 5 dm respectively. © 2017, Editorial Department of Journal of Chinese Inertial Technology.
