講演者略歴
 Tobias Nilsson received his PhD degree in 2008 from Chalmers University of
 Technology, Goteborg, Sweden. His PhD research was mainly focused on
 measuring and modeling atmospheric water vapor using space geodetic
 techniques, especially on GNSS tropospheric tomography and on the effect on
 turbulence on VLBI and GNSS measurements. Since 2009 he is working at the
 Institute of Geodesy and Geophysics, Vienna University of Technology.
 Currently his research is mainly focused on studying high frequency
 variations in the rotation of the Earth using VLBI and other techniques.
 He is also strongly involved in the development of the Vienna VLBI Software
 (VieVS).


講演要旨：
 In geodetic very long baseline interferometry (VLBI) distant quasars are
 observed using a network of globally distributed radio telescopes. By using
 these observations the relative positions of the radio telescopes can be
 determined with cm level accuracy. Furthermore, VLBI can be used to
 determine the Earth rotation and orientation, the positions of the quasars,
 tropospheric and ionospheric delays, and many other parameters. This
 presentation will give an overview of the VLBI technique and how it can be
 used to study changes in the Earth system.
