Setting up a relay for FPV (First Person View) drones to achieve Beyond Line of Sight (BLOS) is an ambitious project that involves both technical know-how and regulatory compliance. Here's a structured approach to help you get started:
1. Capture Video: Use a 5.8GHz video receiver on the relay drone to capture the FPV video feed.
2. Process Video: Connect the receiver to an onboard computer (e.g., Raspberry Pi) to process the video stream.
3. Retransmit Video: Use a 5.8GHz video transmitter to send the processed video back to the ground station.
4. Relay Control Signals: Use 915MHz receivers and transmitters to capture and retransmit ELRS control signals.
Ensure your setup complies with local regulations.
