Abstract

Precise Point Positioning (PPP) is a well-known positioning method that removes, models, or estimates GNSS system errors to reach the optimal position accuracy from a single receiver. The accuracy of static PPP was tested for 523 daily observation files from 75 IGS globally distributed stations observed at the period from DOY 49 to 55 in 2012. Also, the convergence period was examined to reach different levels of the horizontal accuracy to serve two applications: precision agriculture and geodetic control surveying. The accuracy of static PPP was 4, 5 and 9 mm in the north, east and vertical components, respectively. Static PPP needs 60 minutes to reach five-centimeter horizontal accuracy at the 95% confidence level and 24 hours to achieve one-centimeter horizontal accuracy at the 95% confidence level.
