After our issues with the tracker on the last flight we re-secured the antenna and taped the batteries into their holder before wrapping up the tracker again and testing ready for flight.
Another flight with Robert from Wotzup on 1st November enabled us to put our tracker fixes to the test.
We launched on a windy day from Rankin Springs and the predictions had the balloon heading South East, so after a difficult launch we packed up as quickly as possible and started the chase.
The balloon reached a height of 84,821 feet (25,853m) and at its fastest was traveling at 196km/hr, a lot faster than we could so it soon was more than 40km ahead of us. The iGate in the Defender gated the packets at the start and the end of the flight but whilst in the air packets were gated by other iGates in NSW with better signal.
Data from the temperature sensor on the Habduino tracker logged the coldest temperature inside the tracker box at -30C
The flight down was very controlled and the last heard packet above the ground was at a height of 2,250feet (685m) above the ground. Using the HABHUB app we navigated to the last heard location. Once we arrived we were able to hear the trackers beaconing and we received GPS location from the primary and secondary (ours) trackers of the location on the ground.
After trying (unsuccessfully) to find the farmer at the farmhouse we headed out 250m into the field to the location of the payload
The HABHUB app directed us exactly to the location of the payload, a screen grab from the mobile HABHAB app is below just 2m from the payload
The payload is confidential so I cannot show pics of the payload. However we are very happy that our tracker and tracking system and iGate are working well and we are confident we can find and recover our payload.
