(author)Cube satellite (cubesat) is a specific realization of a smallsat that is characterized by its volume changing in increments of 1dm3, or 1U. A (popular) 3U format cubesat is furthermore classified as a Nano satellite, as it typically has a mass between 1 and 10 kg. Within CubeSATs expanding the downlink data bandwidth is one of the central...other 2019

(author), de Man, H. (author), Truyens, D.C. (author), Ferrario, I. (author)Optical communications will complement radio frequency (RF) communications in the coming decades to enhance throughput, power efficiency and link security of satellite communication links. To enable optical communications technology for intersatellite links and (bi-directional) ground to satellite links, TNO develops a suite of technologies in...conference paper 2018

(author)TNO and DLR envision optical free-space communication between ground stations and geostationary telecommunication satellites to replace the traditional RF links for the next generation of Very High Throughput Satellites. To mitigate atmospheric turbulence, an Adaptive Optics (AO) system will be used. TNO and DLR are developing breadboards to...conference paper 2018

(author)Recently TNO has established EBL2; an exposure and analysis facility for testing EUV optics, reticles and pellicles under relevant EUV scanner and source conditions. The facility and EUV source complies with the ASML power roadmap of EUV systems up to a power of 500 W IF. This enables life time testing of EUV optics, reticles and pellicles under...conference paper 2017
