Summary We study optical terminals with both communication and ranging capabilities for their potential use in short range free-space applications, typically encountered within a cluster of microsatellites. For our considerations we assume satellites

Summary A coherent, transparent optical communication system has been developed for free-space lasercomm terminals. The laser synchronisation scheme has been chosen such that the transmission of either an ensemble of subcarrier-modulated signals or o

Optical homodyne receivers are very suitable for free-space laser communications, owing to their high sensitivity and frequency selectivity. Phase synchronization by maximizing baseband signal power is less complex than previously proposed strategies

The design of a 18-aperture receive telescope array demonstrator for optical space communications is presented. Preliminary experimental results and computer simulations show that a telescope array with such dimensions and performance could be used a

In a study for the European Space Agency we explored architectures and terminal configurations for optical cross-links within fleets of microsatellites and assessed the applicability of available technologies. As an example we cover a scenario where

We have adopted the phase modulation technique from the digital Syncbit communication system, and developed an analog transmission system which allows to transmit a set of analog channels between standard bent - pipe satellites. This new analog coher

In ESA's Infrared Space Interferometry mission, a multi-aperture interferometer fed by telescopes will serve to analyse exoplanets orbiting bright stars. Spectroscopy of the planet's radiation could give hints on the possibility of the existence of l
