Being aware of those differences -- the extra software layers included in the experiments and the fact that are used Assisted-GPS sensors -- the results are coherent with what discussed here. Our model achieves on the other side more generality not being dependent on the specific implementation on the given device. Moreover it allows to look directly at what are the theoretical performances we should expect from a GPS sensor without the overhead that is introduced by the operative system of a smartphone.

Our modeling approach is instead at a much lower level and avoids the software layers that alterate what could be the real performances of the sensor. Another difference that arises from previous works is that those discuss Assisted-GPS where the device using the GPS can retrieve the ephemeris data from the network instead of having to listen to the signals broadcasted by the satellites. Our model is again more general with reprect to those since the
