Guy Bomford Prize Lecture 2011 Atmospheric Effects in Space Geodesy
The atmosphere is surrounding the solid Earth and the oceans, and with its variations at time scales from seconds to decades it opens up a wide field of challenging and fascinating tasks in space geodesy. The investigation of these atmospheric effects and the analysis of geodetic Very Long Baseline Interferometry (VLBI) observations have dominated my research in the past decade. Geodetic VLBI w...
متن کاملNon-linear VLBI station motions and their impact on the celestial reference frame and Earth orientation parameters.
The increasing accuracy and growing time span of Very Long Baseline Interferometry (VLBI) observations allow the determination of seasonal signals in station positions which still remain unmodelled in conventional analysis approaches. In this study we focus on the impact of the neglected seasonal signals in the station displacement on the celestial reference frame and Earth orientation paramete...
متن کاملNew VLBI2010 scheduling strategies and implications on the terrestrial reference frames
In connection with the work for the next generation VLBI2010 Global Observing System (VGOS) of the International VLBI Service for Geodesy and Astrometry, a new scheduling package (Vie_Sched) has been developed at the Vienna University of Technology as a part of the Vienna VLBI Software. In addition to the classical station-based approach it is equipped with a new scheduling strategy based on th...
متن کاملVLBI observations of GNSS-satellites: from scheduling to analysis
The possibility of observing satellites with the very long baseline interferometry (VLBI) technique has been discussed for several years in the geodetic community, with observations of either existing satellites of the global navigation satellite systems or of satellites dedicated to realise a space tie. Such observations were carried out using the Australian telescopes in Hobart and Ceduna whi...
متن کاملEVN observations of candidate Compact Symmetric Objects
We present pc-scale images of ten Compact Symmetric Objects (CSO) candidates observed with the European VLBI network (EVN). Five radio sources have been observed at 1.6 GHz, and five more at 2.3/8.4 GHz, the latter subsample with the inclusion in the VLBI array of 3 antennae normally used for geodesy. These objects were selected from existing samples of GHz Peaked Spectrum (GPS) radio sources w...
