At around 10-11am on Sunday, June 28, 2015 Andrew Garratt M0NRD and the South Kesteven Amateur Radio Society are planning to launch balloons from the 10th World Egg Throwing Championship held at the Swaton Vintage Day at Swaton, near Sleaford, Lincolnshire.

As well as telemetry data it is also planned to transmit Slow Scan Digital Video images in 434 MHz. Depending on altitude the signals from a balloon may have a range of up to 800 km, potentially covering much of the British Isles. A real-time track with altitude will be displayed online at http://tracker.habhub.org/

Andrew provided this information on the UKHAS Mailing List : First ever flights for me, so in at the deep end. The ‘egg’ payload will be carried aloft by the balloon and will have a parachute decent into the North Sea when the balloon eventually bursts. There will be SSDV and backup tracker, kindly sponsored by MADHEN http://madhen.net/

LightSail Signal Heard

On the Planetary Society’s website Jason Davis @JasonRDavis reports LightSail is again transmitting on 437.435 MHz, AX.25, 9600 bps FSK.

Jason writes: The Planetary Society’s LightSail test spacecraft reported for duty this afternoon [May 30], heralding the end of an uneasy silence caused by a suspected software glitch. At 5:21 p.m. EDT (21:21 UTC), an automated radio chirp was received and decoded at the spacecraft’s Cal Poly San Luis Obispo ground station. Another came in eight minutes later at 5:29 p.m. The real-time clock on board the spacecraft, which does not reset after a software reboot, read 908,125 seconds—approximately ten-and-a-half days since LightSail’s May 20 launch.

LightSail is not out of the woods yet. Its exact position remains fuzzy, complicating two-way communication. Today’s [May 30] contact marks the first time engineers can compare the spacecraft’s signal with orbital models called two-line element sets, or TLEs. There are ten TLEs associated with the ULTRASat fleet that joined LightSail for a free ride to orbit courtesy of a United Launch Alliance Altas V rocket. Which TLE represents LightSail is unknown, but each radio chirp’s Doppler shift helps narrow down the possibilities.
