EMF14
- Pico balloon (100gram Latex) launched on 31/08/14 from 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 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
