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).<\/p>\n

During its flight at an altitude of about 11,500m.the balloon has been transmitting 5 dBm output of Contestia 16\/1000 on 434.600 MHz USB at 4 minute intervals. Each packet is preceded by 10 seconds of 1Hz pips for manual alignment and a RSID tone for automatic alignment with suitable software. Additionally the payload has the capability for 144 MHz APRS.<\/p>\n

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.<\/p>\n
