SILEX, an experimental inter orbit communication system, is described. It makes use of a laser beam as transmission support between a so called Low Earth Orbit (LEO) terminal, to be installed on SPOT 4, and a so called Geostationary Orbit (GEO) terminal, to be installed on Artemis. For laser beam stability reasons, the laser source, the receiver, the collecting telescope, and other equipment must be monolithically grouped in a carrier structure which, in turn, is mounted on a coarse pointing mechanism making up the whole aerial. The total mass of this assembly can reach 70 to 90 kg and must be firmly held down during launch in order to withstand the quasistatic and dynamic loads. The stiffness requirement for the launch locking devices is up to 130 Hz in the case of the SILEX program. The mechanical configuration and the design requirements of the launch locking devices are discussed.
