Once the basic system is complete and tested potential experiments include 2 way radio communications, video streaming, sunrise launches, etc. ===== Launches ===== * [[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:firefly:fhalp-1|FHALP-1]] - 24/11/07 - landed in the sea - oops 17/22/07 4/11/07 - Test backup system, GM862-GPS, SMS and Radio comms (morse), single camera. * [[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:firefly:fhalp-2|FHALP-2]] - 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. * [[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:firefly:fhalp-3|FHALP-3]] - 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. ====== Goliath ====== 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. ===== Launches ===== *[[http://www.pegasushabproject.org.uk/wiki/doku.php/gumstix_bible:goliath|Goliath]] *[[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1|HAPS-1]] ====== BallastHalo ====== 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. ===== Launches ===== *[[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo|BH 1]] - failed to float *[[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo|BH 2]] - floated for 7+ hrs overnight *[[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:ballasthalo3|BH 3]] - floated but ballast tanks failed to start, landed in Northern France *[[http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:ballasthalo4|BH 4]] - gps failed due to pump, failed to reach float and landed in the Netherlands ====== External links ====== * [[http://www.pegasushabproject.org.uk]] * [[RepairGumstix]]
