Every now and then we try to fly an TTN tracker on an High Altitude Balloon.
Average airtime 57 mS, one packet every minute, no transmission during night time, so with 30 seconds each day I can transmit about 500 packets in a day, which would mean about 1000 minutes , that would be over 16 hours which covers about twice the flight duration.
So far so good I would say. The last flight (sunday 24th of may above the Netherlands) I guess my tracker failed on me, the first launch it dropped from the balloon at 300 meter altitude and came down on the parachute, landed close to home so was recovered. Same payload, same day, other balloon, GPS fix OK (blinking led on the GPS) so we let go of the payload. Last TTN reception was on 65 m altitude, 14 receivers or something, but no reports after that. The RTTY tracker on the same balloon kept working so the balloon could be tracked, Some hours later the balloon bursted at 22 km altitude, and came down with about 2.5 m/s. Suddenly at around 5 km altitude near Limburg (the Netherlands) the bz-ttn-v2 tracker appeared on the map again with over 30 receivers and was received to about 1100 meter altitude close to Scheid in Germany.
Is there a possibility that the registration of the flying payload has been stopped / blocked because of to much receivers or does that nog make sense? (Payload has not been reported so I can not check the conditions)
Next sunday the new bz-ttn-v2 should fly again in a bit better weather conditions.
Thanks for your time,
