It would be interesting to view a skyplot of the GPS satellite trajectories, or at the least output the Dilution of Precision values comparing GPS with GPS+Gali

It would be interesting to view a skyplot of the GPS satellite trajectories, or at the least output the Dilution of Precision values comparing GPS with GPS+Galileo. This would help to illustrate the effect of additional satellites on measurement geometry, and thus on the precision of the output PVT solution.
