Pegasus High Altitude Balloon Project
Based in Eastern UK, student run. By James Coxon (firstname.lastname@example.org)
Uses a gps/gumstix/nokia mobile phone system and parachute for descent.
- 15/10/05 - success, reached 66,000ft traveled 63miles (Suffolk to Lincolnshire)
- 4/03/06 - contact lost after launch, feared to be lost in North Sea
- 15/07/06 - communication test bed (explore alternative methods of communication)
- simple payload using a Motorola WR850G as a flight computer.
- 28/04/07 - Gumstix based, testing 434mhz radio transmitting morse and digital compass.
- 02/11/08 - success, transmitting RTTY and SSTV

Firefly High Altitude Lifting Platform
Modular lightweight payload with simple GM862-GPS backup system (sms and morse radio) - allows for experimental payloads with the fallback tracker system. Once the basic system is complete and tested potential experiments include 2 way radio communications, video streaming, sunrise launches, etc.
- 24/11/07 - landed in the sea - oops
- Test backup system, GM862-GPS, SMS and Radio comms (morse), single camera.
- Launched 10/02/08 - Visual and Radio contact to apogee then loss of contact, landed in somwhere East Cambridge, at present lost. FOUND - see site for details.
- Launched 26/04/08 - Dual balloons - Flight computer died after launch, visual and radio beacon contact lost after 50 minutes. On landing the flight computer restarted and transmitted via sms landing site co-ordinates.
Based on a Gumstix Goliath prototype board with onboard gps, gsm and usb hub. Uses soundmodem software to emulate a packet radio over the onboard soundcard attached to a Radiometrix NTX2. Also has usb storage.
Experimental floating flights with latex balloons and small vents to provide a test platform for ballast tank that will then be used on the Atlantic Halo mission.
- floated for 7+ hrs overnight
- floated but ballast tanks failed to start, landed in Northern France
- gps failed due to pump, failed to reach float and landed in the Netherlands
