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 EUREF stations: 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.
