Time transfer by laser link T2L2 first results

The optical time transfer project T2L2 has been successfully launched from California in 2008 on the Jason-2 satellite. T2L2 permits the synchronization at the pico-second level of remote ultra stable clocks and the determination of their performances over intercontinental distances. The principle is derived from laser telemetry technology with a space equipment designed to record arrival times of laser pulses at the satellite. Since the launch, several thousands of passes have been acquired by the laser ranging community.
