The results have been presented on last laser workshop in Washington. After a short period of maintenance, this mobile station was again engaged in 2003 in the framework of the European GAVDOS project. The primary objective of this project is the establishment of an absolute sea level monitoring and altimeter calibration facility on the isle of GAVDOS, south of the island of Crete, Greece. The GAVDOS project will determine consistently and reliably (1) the altimeter biases and drifts for each satellite altimetric missions (TOPEX/Poseidon, JASON] , ENVISAT, ...) and (2) the bias among different missions. It will also determine the mean sea level and the earth's tectonic deformation field in the region of Crete. The FTLRS was set up in Crete (from April to October 2003 with a two month stop in July and August to avoid too warm days) in order to provide accurate data for altimeter calibrations, orbit validations and accurate positioning. In this talk, we will present the observational balance sheet of the FTLRS Crete campaign and the positioning results obtained with a combination of LAGEOS -1, -2, STELLA, and STARLETTE observations. This solution will be compared to a GPS one.
