Unable to Change Mode from Manual to Guided on BlueROV2 (Without GPS)

I’m working on a BlueROV2 system with ArduSub and MAVROS for underwater applications where GPS is not available. I’ve successfully managed to arm the vehicle, but I’m currently facing an issue when trying to switch the mode from Manual to Guided.

Hi @Eyad -
Welcome to the forums!

The Ardusub firmware will not enter guided or auto mode unless it is being fed a position estimate of some kind…
