Abstract
The Time Transfer by Laser Link (T2L2) experiment, developed by both CNES and OCA, performs ground to ground time transfer over intercontinental distances. The principle is derived from laser telemetry technology with dedicated space equipment designed to record arrival time of laser pulses at the satellite. Using laser pulses instead of radio frequency signals, T2L2 permits to realize some links between distant clocks with time stability of a few picoseconds and accuracy better than 100 ps.
