Holybro X500 Crashed due to Payload E&E Interference

PX4 Autopilot
1

Hello Community,
I have a Pixhawk 6X X500 v2 Holybro drone, with a payload which has some electronics (IMU, Telemetry) which are powered through the Drone Battery PD Module. After takeoff the drone drifted in reverse and crashed. The GPS system for the Drone is F9P RTK, where the drone itself was not picking up Satelites, but for RTK 20 satelites were visible. The GPS, when the drone was Armed and took off, had 4 Satelites, and those dropped drastically to 0 during the flight.
I was not able to take control of the drone after takeoff and during the drift, although RC Link was stable.

Modes used - Position and Altitude.

Does anyone here have encountered similar instances and situations ?

Thank you for your help

In cases like this, providing a flight review of your log will let us check what could be the issue.
But 4 satellites for a F9P is very low, even for single constellation.
If the drone has 0 sats it doesn’t matter how many your RTK has.

If the drone went into Altitude due to no Global position, wind can easily cause the drone to start drifting. There is no position control in altitude.

I would suggest moving the GPS to a better location, e.g a mast on the top of the drone to never have these types of problems.

Anyway, provide the log and people can help you.
