====== PicoAtlas X ====== ===== Aims ===== * To repeat the success of PicoAtlas IX * Launch early morning to look at how timing affects float period ===== Improvements ===== * Add more $$$$$ after radio reset to avoid problems decoding the first string ===== Launch Conditions ===== * Ground windspeed < 5mph * Flight path keeps it within radio rx range for 24hours ===== Launch ===== * Easy launch, filled balloon and released * Perfect weather, <5mph winds, hot day, clear skies * GPS seemed a bit noisy may have been due to desensitised + power saving mode * Started floating around 5km but kept climbing very slowly, sprung a leak and descended over Norfolk * Not yet recovered. ===== Flight Data ===== {{:projects:picoatlas:mappicox.png|}} {{:projects:picoatlas:altpicox.png|}} * Ascent rate = 0.9m/s ===== Conclusions ===== * Harder to float the balloon during the day (however if you manage it it should last for a long time as you'd get a whole day, then night and then potentially another day) * The flight code works well, it was nice to have battery data * Need to have a way of exposing the antenna without it being desensitised
