[57north-discuss] HackSat One ground station

[Dave Hibberd]

I'll stick my nose in here given I'm mildly qualified to work it out -
in a previous life I designed and stuck together
http://www.stacstation.blogspot.co.uk/p/about.html with the help of
undergrad slaves, uh... I mean project workers and designed the radioey
bits on a cubesat with academics until they drove me mad. 

For receiving satellites/ISS, we're pretty far north, so we'd need a decent
skyview south (CampGND might be fun to test a mobile setup?). Yagis, or my 
favourites, axial mode helicals, are pretty easy to build, but I've
never found a rotator solution that I've been happy with - something
could be built using arduinos and gpredict pretty easily, I reckon.

If we're struggling for trx kit the space can "borrow" my
currently unloved and unused UHF radio and transmit "under supervision",
as the amateur license terms dictate if we want to play on the BBS on the 
ISS and the APRS digipeater.

ISS TV, on the other hand, is really exciting - they've got a 2.4GHz
transmitter beaming DVB that we could receive and display using a
transverter up there these days...

I'll be about tonight (and can bring radios if wanted) - feel free to bend my ear
about it all night long (and/or on irc). I don't think I've got any presentations on the
actual space segment, but I might have one kicking about on ground
segment design and testing using high altitude balloons, which I
mentioned when I was half cut on CAH themed thursday!
