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 Universitaet Muenchen, Germany. We are looking forward to welcoming you in Munich.
