How to fuse only latitude longitude and alt

I have a module for image matching between realtime image and google map which can offer only latitude\longitude and altitude.
How can I set the firmware to use the module for localization or navigation?
My vehicle type is plane.

I’ve done this before with success on plane. You’re basically trying to do visual navigation? Correct?

Where’s a link to the module? You’re running it on an nvidia board I imagine?

If you are just outputting a synthetic global position estimate there’s a few things you need to do but I’ll need more information to help.
