On Monday, March 14 the UBSEDS14 balloon, launched by University of Bristol students, passed over Japan and out towards the Pacific, having traveled over 15,497 km since launch.
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 and 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.
