T2L2 is an experience based on laser ranging technique coupled with time-frequency metrology. The goal consists in synchronizing ground and space clocks using short light pulses travelling between the ground and a satellite. The instrument is in phase C/D until end of 2006 and will be integrated to the Jason-2 altimetric satellite which launch is scheduled in June 2008 for a five-year nominal duration. The experiment should enhance the performances of time transfer by one or two magnitudes compared to existing microwave techniques like GPS and Two-Way.
