Paper Abstract

The Small Optical User Terminal (SOUl) is an optical communications package for interconnecting a LEO satellite to future optical data relay terminals and is the subject of an ESA development programme led by British Aerospace. The baseline terminal has a data rate of 2 Mbps over the return inter-orbit link and a mass of around 25 kg. Special features include a periscopic coarse pointing assembly, refractive telescope, passive anti-vibration mount, combined acquisition and tracking sensor, and fibre coupled lasers and receivers. The flight configuration which allows these features to be combined in a compact unit is described in this paper. Details are given of the pointing, acquisition and tracking, optical, and thermal and structural subsystems.
