====== EMF14 ====== * Pico balloon (100gram Latex) launched on 31/08/14 from [[https://www.emfcamp.org/|EMF Camp 2014]] * Onboard: * UKHASnet Node (LPC810 based) called EMF14, wire 1/4 wave antenna (not tuned) * 1 RTTY tracker with GPS * 1 TurboHAB tracker with GPS ===== Flight ===== * Late afternoon launch * Travelled south with a slow ascent rate over London and then out over the Channel into France * EMF14 node * Successfully downlinked packets up to a range of 65km (5000m altitude) before was over the horizon/hill * No packets successfully repeated * Data only downlinked to nodes at EMF Camp, balloon managed to avoid other nodes in Kent and Southampton. * Appears that range is approximately 5deg horizon of the balloon (green circle on spacenear.us) * UKHASnet website worked well * Tested [[https://www.youtube.com/watch?v=bCbf1dv0x-A|hexacopter lifted repeater]] to attempt to re-establish contact but was too far out of range ===== Future plans ===== * More balloon flights with higher altitudes to test range * Better antennas on ground for uplinking. * More ground nodes
