The ILRS 2009 Fall Workshop was held in Metsovo Greece on September 14-19, 2009. The workshop was organized by the ILRS and the National Technical University of Athens, Greece (NTUA).
 |
The 2009 ILRS Technical Workshop (first/second/third circular) addressed a very timely issue: the tracking of
current and future GNSS constellations with SLR. The idea behind this workshop
was to bring together experts from the SLR and GNSS communities providing them
with a forum to discuss all aspects of the theme, focusing primarily on the science
benefits, while tackling also problems arising from the large number of GNSS clients
and the finite resources available to ILRS. In the opening lecture of the workshop,
Professor Emeritus of the National Technical University of Athens, George Veis, the
person to whom the workshop was dedicated on the occasion of his 80th birthday
and who is by most considered the father of satellite geodesy, offered an excellent
historical review of space geodesy, from its inception to present, including all
modern space techniques with many examples and some rare photographic records. |
