Abstract
To assess the accuracy of single point positioning using IGS real time corrections via the Internet in Vietnam. We have processed and evaluated the accuracy of the coordinate components of a sta- tion located in Ho Chi Minh City on November 8th, 2017. The results show that the average accu-racy of single point positioning using RTS of the north, east and up components is 0.26 (m), 0.21 (m) and 0.40 (m), respectively. This accuracy improves about 75% in horizontal and 81% in verti- cal components compared to single point positioning using broadcast ephemeride, and is about 50% less than post-processing results using the IGS Final precise ephemeride and 30s clock corrections (0.11, 0.10 and 0.21m).
