Hi devs

If there an updated ModalAI version of PX4 in the works, do consider getting PX4 not to flag GPS error when none is connected **and** the system is using VIO for position estimates.

I believe PX4 currently flags GPS error as long as a GPS is not connected.

Because of this:
https://github.com/mavlink/qgroundcontrol/pull/9393

QGC is displays a "No GPS Lock For Vehicle" overlaid on the video and obstructs what the Operator can see.

For your consideration pls.

Thanks

Hi @hmlow ,

Thanks for the feedback, which version of PX4 are you running?  Trying to track this down.

Thanks!

Hi

Im using ModalAI 1.11.3-0.2.3.

As a workaround i disabled the overlaid message in QGC by rebuilding a custom version of QGC.
