I am using Matlab's GPS Sensor along with python. I feed in the position and velocity of a generated trajectory in NED to obtain the resulting GPS coordinates in LLA. The input trajectory assumes the surface is flat. Does the GPS receiver simulation model take into account the curvature of the Earth or does it need to be done on the input side?

Hi Muneeb,
We use the WGS84 reference ellipsoid for the conversion between NED and LLA coordinates.
Thanks,
Ryan
