How to navigate with real coordinates in a 3D simulated model

Hi!

I want to simulate a 3D environment of a specific place. What I have is FBX file exported from 3Ds Max which includes LLA(latitude, longitude, altitude) coordinate information. How to convert LLA into unity coordinate system? Is it possible to navigate in the 3D model by the GPS signals obtained by the device? And how to do it?

TKS,
