 UBSEDS14 flying across Pacific

On Monday, March 14 the UBSED14 balloon, launched by University of
Bristol students, passed over Japan and out towards the Pacific,
having traveled over 15,497 km

The University of Bristol Students for the Exploration and Development
of Space (UBSEDS) launched their balloon on Monday, March 8. Powered
by a single AA Lithium Energiser Battery (LR91) the balloon has been
transmitting about 5dBm of Contestia 16/1000 on 434.600 MHz USB at 4
minute intervals as well as APRS during its flight at an altitude of
about 11,000m.

The balloon has a diameter of 1.5m the payload weighs just 21.3 grams.
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.
