Hello everyone,
I’m working on an FPV drone setup for my final year project, using the following components:
- Kakute H7 flight controller
- 4-in-1 ESC
- GPS module
- Video transmitter and FPV camera
- Fiber optic spool for communication
Everything works well when the fiber optic spool is not connected. The GPS module locks onto satellites quickly and maintains a strong signal.
However, as soon as I connect the fiber optic spool to the system, the GPS begins to lose satellites or fails to acquire them altogether. I suspect the issue may be due to electromagnetic interference (EMI) caused by components inside the spool—possibly an inductor or switching circuit—that’s affecting the GPS reception.
Has anyone experienced a similar issue or have any suggestions on how I can isolate or mitigate this interference?
Any help or guidance would be greatly appreciated.
Thank you!
