Analysis of the time series of station coordinates - a comparison of the network and PPP approach

Abstract

Based on the example of fourteen selected permanent GNSS stations of the EPN (EUREF Permanent Network) the differences of time variations of coordinates – velocities – resulting from the network and PPP (Precise Point Positioning) solution are studied. In both approaches the coordinates are determinated using the Bernese software version 5.2. The time series analysis is made using the modified Vaníček´s method. The comparison shows that the results provided by the two methods cannot be accepted as statistically consistent.
