I’m not sure where my question belongs, but it’s about hardware development for an autonomous navigation drone with waypoints. I need help understanding a couple of things.
How does the GNNS/RTK module receive real-time RTK corrections from the ground? I need to add a LoRa radio that connects to the RTK module, and I have a lot of questions about that. For example, how do I configure that radio, like channels and spreading factor? GPT told me it connects directly to the serial port and that for the GPS module, this is completely transparent… I don’t know, Rick.
The other, closely related question is how it receives the ground control status from all the drones. Would it need another LoRa module along with another processor that connects to the flight controller via UART/MAVLink? What protocol is used to prevent collisions between the signals from all the drones? Should this radio operate on a different frequency? If I use 433MHz for GPS/RTK, I’ll use 915MHz to obtain status data, waypoint reached, battery level, etc. What’s the standard way to connect multiple drones to receive data and send basic commands like “takeoff” or “return”?
Thanks for your help.
