Abstract

From GPS week 2034, the France Centre National d’Etudes Spatiales (CNES) started to provide accurate products of ephemerides and clock corrections for GALILEO satellites with ambiguity resolution capability. We investigated the accuracy of precise point positioning with ambiguity resolution using only GALILEO at 12 IGS permanent stations in the European region. The results show that the accuracy of 24-hour static solution is (2.4, 3.8, 7.4) mm and kinematic solution (9.7, 8.8, 26.8) mm in the North, East and Up components. Compared with GPS only, the East and the Up components of GALILEO static solution are still less accuracy than ½. Meanwhile, the accuracy of GALILEO's kinematic position is not much different from GPS.
