We present a ground-to-space quantum key distribution (QKD) mission concept and the
accompanying feasibility study for the development of the associated low earth orbit …

Space-to-ground optical data links enable higher data rates, require less electrical power,
and allow more compact system designs than their corresponding RF counterparts. They …

Future spacecraft will require a paradigm shift in the way information is transmitted, in light of
the continuous increase in the amount of data requiring space links. Current radio-frequency …

Delivery of large volumes of data from low-Earth orbit to ground is challenging due to the
short link durations associated with direct-to-Earth links. The short ranges that are typical for …

The CubeSat Laser Infrared CrosslinK mission is a joint Massachusetts Institute of
Technology (MIT), University of Florida (UF), and NASA Ames Research Center effort to …

Free-space optical communications have held the promise of revolutionizing space
communications for a long time. The benefits of increasing the bitrate while reducing the …

In a world of global satellite communication networks, it is crucial to ensure the security of
these data links. QUBE is a project that will develop and launch a CubeSat for the downlink …

In this article, we present the first demonstration of an optical communications downlink from
a low-earth orbiting free-flying CubeSat. Two 1.5 U vehicles, AC7-B&C, built under NASA's …

Future spacecraft will require a paradigm shift in the way the information is transmitted due
to the continuous increase in the amount of data requiring space links. Current …

To overcome data rate limitations of RF communication links with satellites, TNO and DLR
envision optical free-space communication feeder links for next generation high throughput …
