<p class="MsoNormal">We've been using LoRa modules in the Project Horus 'flight termination' payload (which also has GPS tracking) for a few years now. We run them on the 434 MHz ISM band at 25mW, for command & control of the cutdown mechanism (nichrome wire).
We have a whole ecosystem of software based around communicating with the cutdown payload and transferring data around the chase car's network.<o:p></o:p></p>
