On Thursday, March 17 the UBSEDS14 balloon, launched by University of Bristol students, had successfully crossed the Pacific and was above Arizona, having traveled over 24,500 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.

UK STEM 434 MHz Balloon Flight to Release Plane

MARS BalloonElysium, a MARS Balloon flight is expected to launch at noon (+/- 1 hour) on Sunday, October 26. The 434 MHz USB signal should cover much of the UK and can also be received world-wide online using the SUWS WebSDR.

The balloon will be launched from the Mendips (51.254, -2.714) and is expected to travel almost directly east for a landing near Basingstoke. The estimated flight time is 135 minutes with a peak altitude of 30 km.

Callsign $$ELYSIUM frequency 434.250 MHz, USB RTTY 50 Baud 560 Hz Shift ASCII-7 no parity 2 stop bits

55 science experiments submitted by 36 schools from across the UK will soar 30 km up into the atmosphere and back. The flight will also contain a plane from Bristol SEDS, activated before launch and to be released at peak altitude, with a separate onboard tracker. Expected to fly further east than Basingstoke.

Callsign $$UBSEDS3 frequency 434.600 MHz LSB RTTY 50 baud 400 Hz shift ASCII-8 no parity 2 stop bits.

Silverstone B-64 balloon still flying

Track of the B-64 balloon

Track of the B-64 balloon

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.

Help needed to track 144.390 MHz APRS Balloons

James Cutler KF6RFX and Benjamin Longmier KF5KMP - University of Michigan

James Cutler KF6RFX and Benjamin Longmier KF5KMP University of Michigan

Benjamin Longmier KF5KMP and his team are looking for stations in the Azores and Portugal to help track their balloons.

On the UK High Altitude Society (UKHAS) group he writes:

My team (Project Aether) launched a balloon recently that did a lap around the Midwest in the US, headed East past Nova Scotia and is still floating strong. We don’t have any contacts in the Azores or Portugal, and are requesting help in contacting some of these folks that might be able to decode our APRS packets.
