Native spherical (WGS84) coordinates?

edit

Hello all,

I'm looking to build a simulation where I can accurately bookkeep my robots position in geodetic coordinates (WGS84 datum).

Unfortunately the ROS+Gazebo+Hector GPS plugin route isn't likely to work, exactly because I'm trying to simulate vehicles at high latitude (near the poles), and traveling large distances O(10 km).

Is it possible for Gazebo to run a simulation natively in spherical coordinates? I haven't been able to find any resources to date on this.

If not, have any others found themselves in a similar situation? Outside of writing a dynamical model in MATLAB or similar, have others found an acceptable solution?
