Would it be possible to interface the second GPS on the ground station and compare the ground station's GPS position to the UAV's GPS position ?? Would it be a primitive DGPS ?

The position between the ground station and the UAV could be more accurate !!! It would now be great to upload the ground station's position to the UAV. This way, navigation thru waypoints would be more accurate ...
Please tell me if I'm wrong.
