[OZAPRS] High Altitude Balloons

[Mark Jessop]

That would have been a Project Horus writeup - Matt (VK5ZM) and I (VK5QI)
are both members, and were involved in that writeup :-)

Lots to think about when doing a high altitude balloon launch:
- Authorization from CASA
- Flight path predictions (i.e. how to know when *not* to launch! -
http://predict.habhub.org/ )
- Balloons, helium, lift calculations, etc ( http://habhub.org/calc/ )

and then of course...
- Radio tracking (be it via APRS, RTTY or something else).
- Mapping of balloon flight paths (http://tracker.habhub.org/ is much nicer
than aprs.fi - it will do flight path predictions during the flight!)
- How to actually chase a balloon and get to the landing site before the
payload does :-)
- Mapping the balloon flight path without an internet connection (hint:
https://github.com/projecthorus/oziplotter )

... unfortunately I need to head off to work, and I can't easily answer
emails to this list from my phone.

I've been slowly working on write-ups for a lot of the above bits. The
mapping side of things is mostly covered by the OziPlotter documentation
linked above. The 'how to chase' bit is still to come...
