Bristol student balloon mission
On 21 March the UBSEDS14 balloon, launched by University of Bristol students, completed its circumnavigation of the Northern Hemisphere.
During the flight, at an altitude of about 11.5km, the balloon transmitted telemetry data at four minute intervals using Contestia 16/1000 on 434.600MHz USB, with an output power of just 3mW.
Each telemetry packet was preceded by 10 seconds of 1Hz pips for manual alignment and a RSID tone for automatic alignment with suitable software.
Additionally the payload had the capability for 144MHz APRS.
