#2 Global transform problem in simple sim

[Stephen Balakirsky]

I am using my own derrived transform to convert from
local to global coordinates in the vehicle level
process. This transform works when running usarSim and
not when running simpleSim.

I realize that I should be using the built in transform
from navDataExt, but I feel that this points to some
bug in the navDataExt message.
