Change the reference of local position?

Hello,

Is it possible to change the reference of local_position with a custom gps position ?

Thanks

It is possible to add a device as a secondary GPS and feed in a NMEA stream which does this. Not a trivial task however. My curiosity can’t stand it. Why do you want to do this?

I need X Y and Z coordinates relative to a reference point that is not the Pixhawk’s starting location !!
