UBSEDS18 Solar Powered Balloon

On Sunday Bristol SEDS students plan to launch a 434 MHz and APRS solar
powered balloon that may travel around the world.

Another pico launch from Bristol this Sunday, December 11 between 0500 and
0530 GMT. This launch is using a 1.9m envelope and longer payload train,
and so we have a NOTAM in place. The flight is predicted to head south-east
towards France.

The payload will be transmitting Contestia 16/1000 on 434.610 MHz USB. Each
transmission of Contestia 16/1000 will be preceded by 10 seconds of pips
and RSID.

The Contestia transmission rate will be once every 30 seconds during launch
and when power is available during the day. Otherwise the transmission rate
will be once every 2 minutes. Hopefully the tracker will operate from dawn
to dusk, and maybe also during the night.

The tracker will transmit APRS outside countries where the amateur license
is not permitted airborne (like the UK). Additionally it will test APRS on
145.825 MHz, with an output power of +26 dBm (400 mW).

More details will appear on the website
