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...

Three independent time transfer techniques are in use in Observatoire de la Côte d'Azur (OCA): GPS, TWSTFT and T2L2. In Autumn 2013, a GPS receiver relative calibration campaign has been carried out. The result of this campaign, primary intended to compare GPS with T2L2, have allowed the calibration of the TWSTFT link between OCA and OP. We...
