Prospective Performance Budget of the T2L2 Experiment

The Time Transfer by Laser Link (T2L2) experiment [1], [2], under development at OCA (Observatoire de la Cote d'Azur) and CNES (Centre National d'Etudes Spatiales), France, will be launched in 2008 on the altimetric satellite Jason 2. The experiment principle is issued from laser telemetry, i.e. the timing of transmitted and reflected laser pulses. This paper is a prospective study of the T2L2 performance budget lead on simulations of the stations network geometry, the orbit parameters and the instrumental error budget.
