We were able to send, track and recover this high altitude balloon. Again, we decided to join forces together with team Jebedias and shared the same balloon to carry two independent payloads.
Great day, late August, amongst friends and family.
New improvements:
- First time I was using LORA @ 433 MHz and RTTY @ 433 MHz. Impressive the performance of LORA
- Decided to build a LORA gateway, that comes with us on the car, receives the LORA messages and tracks the path of the car.
Some conclusions drawn from this launch:
The radio on the top payload totally jammed the GPS on the bottom payload. So, we were never able to retrieve a valid GPS sync from the bottom payload. The GPS on the bottom payload did work perfectly. Maybe because the two payloads were too close, I don't know. I guess I'm not going to try it.
During preparation we noticed that the second GPS wasn't working but we decided to attempt the launch anyway.
The Balloon was launched at 11:30 in the morning, reached the maximum altitude of 30.995m at 15:33 and then started his descent hiting an olive tree at 17:39.
The trajectory changed a few times but we were able to track it using LORA and RTTY (harder, coz we had to get out of the car and set the YAGI antenna) all the time.
This time I also had a GPS on my chase car and I uploaded to HABHUB the location of it.
The following image shows the trajectory of the balloon (yellow) and the trajectory of my chase car (red). As you can see, the ballon started to go east, but suddenly geared towards west. After a while we went back east.
This is where it ended, on top of an olive tree.
