The aim will be to fly a high altitude long duration floater from the UK over the UK with telemetry but also SSTV and SSDV transmissions from the onboard camera. text/html 2012-10-01T22:05:06+01:00 James Coxon http://www.pegasushabproject.org.uk/wiki/doku.php/start?rev=1349125506&do=diff Updates * Atlas3 - 11/11/11 - launched, floated for 30minutes at 36-37km, burst and dumped over North Sea, payload worked excellently * Constructing the Atlas flight computer for a second floater launch May 2011 * Atlas launch 13/11/10 - Summary: great launch, gps fail, didn't float, crystal oven worked well, dumped into North Sea. * Currently working on BallastHalo 6 - just finished designing the new flight computer and am currently doing some testing on maintaining the radio crystal… text/html 2012-06-27T08:57:43+01:00 James Coxon http://www.pegasushabproject.org.uk/wiki/doku.php/ideas:rtl-sdr?rev=1340783863&do=diff * Get a copy of linrad lir03-39.tbz * Install the rtl-sdr library rm -r /usr/src/rtl-sdr* cd /usr/src git clone git://git.osmocom.org/rtl-sdr.git cd rtl-sdr/src mv librtlsdr.c librtlsdr.c.old wget http://sm5bsz.com/linuxdsp/archive/rtlsdr/librtlsdr.c mv tuner_e4k.c tuner.e4k.c.old wget http://sm5bsz.com/linuxdsp/archive/rtlsdr/tuner_e4k.c cd .. mkdir build cd build cmake ../ make make install text/html 2011-11-12T15:08:36+01:00 James Coxon http://www.pegasushabproject.org.uk/wiki/doku.php/missions:atlas:atlas3?rev=1321110516&do=diff Aim * To explore the phenomena of 36km floats with Howyee balloons * To test the Atlas flight computer at altitude Components * Atlas PCB * ATmega328 + 8Mhz Crystal * Radiometrix NTX2 10mW 434.075Mhz + Crystal oven * GPSbee (Ublox 5) GPS * 3 x DS18b20 * Photosensor
