ARLA/CLUSTER: Aviação preocupada com o futuro gigantesco radiotelescópio SKA na África do Sul e Australia

[João Costa > CT1FBF]

Aviation worried about the Square Kilometer Array

The giant *S-K-A* radio telescope chosen to be in both South Africa and
Western Australia has created fears that its spectrum silence zone could
see jet aircraft being redirected.

It will be 100 times larger than any current radio telescope and may
revolutionise our understanding of the universe.

While its South African end is still being built at Karoo, the local
aviation
industry is concerned about the restrictions it will bring to some radio
frequencies. To function it will need to be protected from interference,
thus it has a designated radio quiet zone.

There does not seem to be a problem with the project quiet zone about 80km
from Carnarvon in Western Australia. However aviation in South Africa is
concerned it could affect communication between pilots and air traffic
control.

The S-K-A in a draft proposes a ban on frequencies from 100 MHz to 25.5 GHz
which include those used by aircraft. Both the S-K-A and the aviation
industry are discussing the matter to find a possible solution.
