We present experimental results on a bidirectional link between a telescope array and a
single-telescope antenna. Each telescope is coupled to a single-mode fiber. A fine tracking …

Bidirectional ground-satellite laser links suffer from turbulence-induced scintillation and
phase distortion. We study how turbulence impacts on coherent detection capacity and on …

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 …

In this article, we demonstrate a real-time implementation of the digital combining of 10
Gbit/s signals received by a multi-aperture terminal over a 3 km free-space optical link. The …

Current LEO satellites are generating more and more data which needs to be brought back
to Earth for processing and analysis. Robust optical communications links are compulsory to …

Accurate knowledge of information data capacity between a spacecraft and optical ground
stations is of utmost importance for assessing the feasibility of laser downlinks in future high …

Bidirectional ground-satellite laser links suffer from turbulence-induced scintillation and
phase distortion. We study the impact of turbulence on coherent detection and the related …

In a free-space optical communication system employing fiber-optic components, the
phasefront distortions induced by atmospheric turbulence limit the efficiency with which the …

This paper describes the technical challenges and the experimental set-up for an optical
feeder-link demonstration between ESA's optical ground station in Tenerife, Spain, and the …

Free-space coherent laser downlinks can potentially provide high data rates in space-to-
Earth communications, and are a key enabler for future optical information systems in space …
