Scheduled for Sept 4, 2016
Location: Vila Marim, Vila Real - Portugal
Major improvements on this launch:
- Transmition will be on RTTY and LORA, both at 434MHz, using RFM98W
- There will be a temperature and pressure sensor inside the balloon, close to the neck, that will measure these across the entire flight
- Inisde the payload another temperature and pressure sensor, plus an humidity sensor will record these conditions during the flight.
- Batery voltage will be measured and recorded
- There will be a ballast valve that is set to release 100ml of alcoohol (water will freeze at those heights) at around 20.000 meters. I want to know how the balloon will behave with the release of ballast.
- There will be a helium valve set to release helium during 60 seconds, at 30.000mts. I want to know how the ballooon will behave with the controlled loss of lift
- Using a W25Q32BVS 32M-bit serial flash memory to log all the information of the flight.
- All controlled from a Arduino Pro Mini running at 3.3V, 8MHz
- LORA gateway in the chase care collecting the telemetry coming from the Payload and uploading it through a ESP8266 Wi-Fi modem to the HABHUB site.
- Chase car position will be uploaded as well
- Improved the SNR of the received signal, both on RTTY as well as LORA
