The anticipated capacity benefit of optical satellite communications has triggered a cascade of technology developments. In this paper, we present three such technologies, namely; i). A cube satellite laser terminal (CubeCAT), ii). A lower Earth orbi

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 atmospheri

The continuous strive for increased sensitiv ity and higher resolution of space based telescopes can only be satisfied with larger primary mirrors. There are quite a few challenges in launching large mirrors in space such as surviving the stress crea

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 satellites. This paper provides a feasibility assessment of such links

To increase the collecting power and to improve the angular imaging resolution, space telescopes are evolving towards larger primary mirrors. The aerial density of the telescope mirrors needs to be kept low, however, to be compatible with the launch

Over the last decade TNO has developed a deformable mirror concept using electromagnetic actuators with the main advantages of having very low non-linearity and hysteresis, low power consumption, and high inherent reliability of the actuators. TNO re

This paper proposes the conceptual design of a mechanical stimulator that uses a tissue engineering strategy to develop a diarthrosislike structure in vivo. The adopted design approach is based on a function analysis. The approach has resulted in the
