ARLA/CLUSTER: Força Aérea dos Estados Unidos quer melhorar as comunicações em HF

[João Costa > CT1FBF]

USAF wants to improve HF communications

* New Scientist* magazine reports the US Air Force is working on plans to
improve HF radio propagation by releasing ionised gas in the upper
atmosphere using a fleet of micro satellites

As well as increasing the range of radio signals, the USAF says it wants to
smooth out the effects of solar winds, which can knock out GPS, and also
investigate the possibility of blocking communication from enemy satellites.

The story says there are at least two major challenges. One is building a
plasma generator small enough to fit on a CubeSat – roughly 10 centimetres
cubed. Then there’s the problem of controlling exactly how the plasma will
disperse once it is released.
