Popis:	The following contribution provides a holistic view concerning the prospective VLBI observations of geodetic satellites in the era of GGOS and their impact on various geodetic products. The aspect of VGOS-type satellite observations in the GGOS era is investigated with the use of Monte-Carlo simulations carried out with the c5++ analysis software. The basis of our study form three-day VGOS schedules, which include both quasar and satellite observations. The latter are realized with the use of several Galileo satellites, which are located on different orbital planes. Both observation types are used to derive satellite orbits and estimate common station-based and global geodetic parameters. The impact on classical geodetic parameters (station positions, ERP), caused by additional satellite observations and the orbit determination process, is investigated with the use of different satellite observation precision levels. We also provide insights concerning the quality of the determined satellite orbits and geocenter estimates. In addition, the scheduling aspects and the technical feasibility of the presented approach are also discussed. EGUsphere
