Analysis strategies and software for geodetic VLBI

Abstract

This article describes currently used analysis strategy and data analysis software for geodetic VLBI.Today's geodetic observing strategies are shortly presented, and the geodetic VLBI observables and data modeling are briefly discussed. A short overview is given on existing geodetic VLBI software packages and the statistical approaches that are applied. Necessary improvements of today's analysis software are described. Some of the future expectations and goals of geodetic VLBI are presented and the corresponding consequences for the VLBI technique are explained. This includes consequences in terms of technical development and corresponding improvements in data modeling and analysis software.
