UBSEDS balloon envelope

In March the 434 MHz and APRS balloon UBSEDS14 flew around the northern
hemisphere. On Saturday, April 30 a new balloon UBSEDS15 will be launched
by the University of Bristol Students for the Exploration and Development
of Space. The signal from the balloon may have a range of 400 km so should
be receivable across the southern UK.

Another pico launch from Bristol this Saturday, April 30. The launch will
be at 0900 ISH. As before the payload is transmitting on 434.600 MHz USB,
with an output power of about +6dBm. Each transmission of Contestia 16/1000
will be preceded by 10 seconds of pips and RSID.

This payload uses solar panels to generate power. Hopefully the
transmission rate will be once per minute during the day, and once every
two minutes at night (if the payload operates at night). Its also capable
of transmitting APRS packets, but will only do so outside countries where
the amateur license is not permitted airborne (like the UK).

It will probably head south quite quickly after launch, so trackers on the
south coast are particularly appreciated. More details will appear on the
website http://www.bristol-seds.co.uk/flights.html

Despite the weight constraints the team have managed to employ
sophisticated Geofencing technology to prevent the balloon transmitting
when over certain countries and also to select different APRS frequencies
depending on the territory being overflown.
