How to use GPS to do autonomous robot navigation?

[Masoumeh]

Hi Mattieu,

I want to do navigation based on a gps map, would you please guide me what should I do? how can the robot go to a location with a specifed gps coordinate?

Is it possible to load gps map or an empty map into the rtabmap database??
thanks
