Abstract

CNES and CODE are two of the IGS Analysis Centers. Both Centers currently provide precision satellite products supporting PPP-AR GPS and GALILEO. To determine the accuracy of PPP-AR GPS+GALILEO for 24h solution, we processed PPP in 90 days of GNSS data from 01/01/2022 to 31/03/2022 of 4 permanent GNSS stations in the South East Asia region in two options: using products of CNES and CODE. The results show that using the CNES product gives a better success rate of ambiguity resolution (97.0% vs. 94.4%), and the positioning accuracy of (2.8, 3.1, 10.4) mm is better than the CODE (12, 30, 8)%, respectively in North, East and Up components
