Rooftop satellite receivers can look out of place with the historic surroundings of ancient cities. In the first-time participation with ESA, a Greek company is working to solve this.
The project is to develop a kind of satellite receiver known as a planar array. Unlike more commonly seen parabola-shaped dishes, planar arrays pick up less interference from other satellites. Another feature is their square, flat shape.
Low-visibility is a major concern in Greece; unsightly satellite dishes would sit uncomfortably alongside historical cityscapes and ancient Hellenic architecture. The first step to achieving this was to reduce the size of planar arrays to 36 cm in diameter.
The flat design means the antennas are easier to camouflage. The structure offers users the opportunity to apply colourful covers that help satellite equipment blend in to the surroundings. Designs being considered include house bricks, clouds or even a cat. The final product would be a suitable solution for areas where restrictions exist for satellite installation.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
