Dear Colleagues,
The ESA Topical Team on "Geodesy Applications of the ACES Mission" is
pleased to invite you to the workshop on
"ACES and Future GNSS-based Earth Observation and Navigation"
http://www.iapg.bv.tum.de/aces.html
Atomic Clock Ensemble in Space (ACES) is an ESA mission based on the
performances of a new generation of atomic clocks operated in space, on
board the International Space Station in 2012-2015. The ACES clock
signal will reach fractional frequency stability and accuracy of 1 part
in 10-16 opening attractive perspectives for testing Einstein's theory
of general relativity. The two-way microwave link developed for the ACES
mission will allow frequency comparison of ground microwave and optical
clocks at the 10-17 level. The ACES frequency reference will be
connected to an on-board GPS/(GALILEO) receiver which will ensure
precise orbit determination of the ACES clocks and at the same time will
allow to develop applications in different areas of research. Besides
fundamental physics, the geodesy part of the ACES mission is related to
scientific objectives in the field of the LEO orbit determination,
combined opticalµwave ranging and time/frequency transfer,
determination of gravity potential using ground optical clocks, GNSS
radio-occultation and GNSS scatterometry.
Scope of this workshop is to bring together a wide scientific community
and exploit the ACES potential for applications in the fields of
geodesy, Earth observation and navigation.
The workshop will take place on the 26-27 May 2007 at the Institute of
Astronomical and Physical Geodesy, Technische Universitdt M|nchen, Germany.
We are looking forward to welcoming you in Munich.
The workshop Organizing Committee:
Drazen Svehla - IAPG, TU M|nchen, Germany
Prof. Markus Rothacher - GFZ Potsdam, Germany
Prof. Christophe Salomon - LKB/ENS, Paris, France
