Analiza vpliva uporabe popravkov ur satelitov pri uporabi metode Precise Point Positioning (PPP)

High rate 30 seconds vs clock interpolation in Precise Point Positioning (PPP)

Abstract:

The development of GNSS technology (Global Navigation Satellite Systems), including GPS technology (Global Positioning System), and the increase of accuracy and precision of the International GNSS Service (IGS) products, make Precise Point Positioning (PPP) technique more and more attractive. The IGS service provides clock products even for high rate determination – 30 seconds. The article is analyzing and comparing the 30 seconds high rate data and the interpolated data from 300 seconds in static PPP determination. Three stages of analysis are done: in the first stage the impact of data products on LC and PC postfit residuals are accounted, in the second stage the impact on wet troposphere delays (WTD) is analyzed and in the third stage the coordinate variation on North, East and Up component is presented. The stations that were analyzed are two IGS stations, BUCU and SOFI and two EUREFstations: COST and AUT1. The results presented an increase of 30% for LC postfit residuals in the case of interpolated data and no obvious influence on PC postfit residuals. In the case of WTD only a difference of a few centimeters were determined and in the case of coordinate variation the largest difference was present in the North component for station COST of 5.79 mm.
