Silverstone B-64 balloon still flying around the world

Posted by K R on

The B-64 balloon launched at 06:51 GMT on July 12, 2014 from Silverstone is still in the air flying at just over 12,000 metres and transmitting on 434.500 MHz Contestia 64/1000 and also APRS. On Saturday, October 3 Phil Heron MI0VIM reported decoding data while it was over the North Atlantic ocean, coming up to the 6th time it would pass the United Kingdom on it’s continuing journeys around the world. B-64 was built by radio amateur Leo Bodnar M0XER, he made both the plastic foil envelope and the solar powered transmitter payload which weighs just 11 grams. Leo has utilised some clever techniques storing positions when the balloon is out of radio contact then later transmitting a log file of previous locations in the comments field of the APRS packet. This enables a fairly complete path to be built up. B-64 only stores 5 days worth of data, where you get a straight line on the track it has been out of radio contact. Track Current Location Here via AMSAT-UK.
