Err, my fault, we don't actually build Satellites anymore. The last one
was in the 70's http://www.asri.org.au/web/satellites/wresat
Newsat buy then from other people, just as Leighton's/Nextgen would.

However we should. Technology transfer should be part of any technology
contract worth 620 million.

An actual satellite in Geosynchronous orbit is worth around 30 million
dollars plus extras.
At around 280 million each, that's a lot of extras. Surely there's some
technology transfer costs in there somewhere.

Correct for an MPEG television repeated signal, not necessarily correct
for new beam formed high frequency data streams. 

Pages 17 to 10 of
Result negligible signal loss.
