Modeling Special Handling Source Positions in the GFZ VLBI Solution
Abstract
Based on the GFZ VLBI solution obtained using the Vienna VLBI Software (VieVS), we estimate time series of the ICRF2 special handling sources. We investigate their time-variable positions based on our VLBI solution, which compared to ICRF2 includes the more recent VLBI observations. In a next step, the parameterization of the special handling sources is appropriately extended by allowing a linear variation in time. We present our first results, and we propose further studies with the aim of improving our research.
