Whilst most high altitude balloons only transmit data (telemetry and sometimes images) down to the ground, there are several applications for sending data to a balloon, for example: Requesting re-send of missing image packets Balloon repeating of other balloon telemetry Commanded cutdowns etc. My PITS software and LoRa gateway already […]

Pi Pico Balloon Tracker

Balloon Tracking As you may know, my main hobby is flying weather balloons, using GPS/radio trackers to relay their position to the ground, so they can be tracked and hopefully recovered. Trackers minimally consist of a GPS receiver feeding the current position to a small computer, which in turn controls […]

T-Watch 2020 HAB Tracker

Earlier this year I posted an article about the TTGO Watch with the optional LoRa/GPS board, and how to program it to track LoRa high altitude balloons. Since then I’ve used it on a real flight where I found it ideal for checking that the balloon tracker was running fine […]

HAB Watch

One of the nice things about LoRa vs traditional radio modulation techniques used by high altitude balloons, is that LoRa chips include decoders.  So whereas RTTY and APRS generally require a PC to decode the signal, LoRa only needs a basic microcontroller.  So LoRa receivers are cheap and small. I’ve […]
