(author)Free space optical (FSO) satellite communications has very attractive properties for Quantum Key Distribution(QKD). The quantum channel loss and noise are major factors in setting the maximum achievable secure key rate of QKD systems. Primarily for a LEO satellite node and the BB84 protocol a number of technologies are proposed to reduce the...conference paper 2021

Human, J.D. (author), Liebig, T. (author), den Breeje, R. (author), Gruber, J.M. (author), Moens, T.M.N. (author), Saathof, R. (author)Multiple groups world wide are currently developing laser communication terminals for downlinking data from satellites in the LEO orbit directly to earth in the so call DTE (Direct To Earth) configuration. These terminals will require a network of ground stations to downlink their data. The challenge for the communication industry is the...other 2019

(author)For the next generation of very high throughput communication satellites, free-space optical (FSO) communication between ground stations and geostationary telecommunication satellites is likely to replace conventional RF links. To mitigate atmospheric turbulence, TNO and DLR propose Adaptive Optics (AO) to apply uplink pre-correction. In order...conference paper 2019
