Testing radio range is often a large component of these hobbies. Amateur radio is often used with packet radio to communicate at 1200 baud, using the Automatic Packet Reporting System back to the ground station. Smaller packages called micro or pico trackers are also built and run under smaller balloons.
Amateur radio high-altitude ballooning (ARHAB) is the application of analog and digital amateur radio to weather balloons and was the name suggested by Ralph Wallio (amateur radio callsign W0RPK) for this hobby. Often referred to as "The Poor Man's Space Program", ARHAB allows amateurs to design functioning models of spacecraft and launch them ...
Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching 36,010 metres (118,140 ft).
The presence of the high-altitude balloon comes approximately one year after a high-altitude balloon originating from China drifted over the US, causing national attention and political tension.
VanHerck, meanwhile, warns that the Chinese balloon program remains active and that the U.S. has failed to develop the systems it needs to detect high-altitude spy balloons before they pose a threat.
A balloon the US was tracking across the country has now left US airspace and was likely a “hobby balloon,” NORAD said in a statement Saturday.
The aerostat consists of four major parts or assemblies: the hull and fin, windscreen and radar platform, airborne power generator, and rigging and tether; they are kite balloons obtaining aerodynamic lift from relative wind and buoyancy from being lighter than air.
