Abstract

The Integrated Precipitable Water Vapour (IPWV) parameter is applied to the description of atmospheric changes in the area of climatology, meteorology and geophysics. This paper presents research results concerning the determination of the IPWV parameter, using GPS satellite technique. The IPWV term was designated on the basis of values of the Zenith Wet Delay (ZWD) product. The ZWD parameter was estimated using undifference GPS code and phase observations in the Precise Point Positioning (PPP) method. The computations were conducted in the magicPPP and APPS software packages for GPS observations from the REF1 reference station. The REF1 reference station was installed at the military aerodrome in the town of Deblin, in Ryki rural region, in Lublin V of south-eastern Poland. The paper presents and compares the results of the IPWV parameter from the magicPPP and APPS software packages. In addition, the IPWV parameter is estimated by means of an empirical troposphere model of the RTCA-MOPS solution. The mean difference of the IPWV term between the APPS and the magicPPP solution equals 3.6 mm, with the RMS bias of approximately 0.4 mm. Moreover, the mean difference of the IPWV parameter between the APPS and RTCA-MOPS solution amounts to 5.7 mm, with the RMS bias nearing 0.2 mm. In addition, the mean difference of the IPWV term between the magic PPP and RTCA-MOPS solution is approximately 2.1 mm, with the RMS bias being close to 0.6 mm. [ABSTRACT FROM AUTHOR]
