[Martin Rothfield] and different newbie radio operators from San Francisco Top Altitude Ballooning (SF-HAB) handled convention attendees to the 2022 Hackaday Supercon to the release of 2 Top Altitude Balloons (HABs). At the morning of November sixth, the 2 balloons had been introduced from a park around the boulevard from Supplyframe DesignLab in Pasadena, California.
Seven days after its release from Southern California, one of the crucial balloons was once over Tajikistan cruising eastward at an altitude of 42,000 ft (12,800 meters). Balloon W6MRR-26 was once already coming near China the place it’ll proceed its superb global excursion to portions unknown. The second one balloon (name signal W3HAC-11) landed in northern Arizona the place it has endured transmitting each time it receives energy from the solar.
Each and every balloon carries a tiny payload — a published circuit board powered simplest via small photovoltaic cells. The board features a microcontroller, a GPS module, and a Susceptible Sign Propagation Reporter (WSPR) radio transmitter. The transmitted operates at the 20 meter newbie radio band at round 14 MHz.
WSPR beacons may give time, altitude, and placement data. The WSPR telemetry is then relayed by the use of WSPRgates the use of Computerized Packet Reporting Gadget (APRS) onto the Web. The accrued data will also be considered and mapped on internet sites equivalent to aprs.fi.
