We discuss an optical ground terminal receiver architecture based on multi-aperture digital
coherent combining. Experimental results using four receivers demonstrate lossless …

Space terminals for free-space optical communication systems are under constant pressure
to reduce their size, weight, and power profiles. Ground terminals with large collection areas …

Space-to-ground optical communication systems can benefit from reducing the size, weight,
and power profiles of space terminals. One way of reducing the required power-aperture …

The next generation free-space optical communications infrastructure will need to support a
wide variety of space-to-ground links. As a result of the limited size, weight, and power on …

We report on a demonstration of a bidirectional, multi-aperture free-space optics (FSO)
system and discuss general system design aspects. A multi-aperture terminal is used for …

The next generation free-space optical (FSO) communications infrastructure will need to
support a wide range of links from space-based terminals at LEO, GEO, and deep space to …

This paper describes a lasercom terminal using spatial diversity to mitigate fading caused by
atmospheric scintillation. Multiple receive apertures are separated sufficiently to capture …

Existing radio-based satellite up-and downlinks are reaching their limits in terms of
transmission rate. In order to enable higher data rates, optical links are being researched …
