Dead reckoning and sensor fusion are the real answer. Over 20 year old Etak patent:

"Based on the previous position of the object, the GPS derived position, the velocity, the DOP(dilution of precision) and the continuity of satellites for which data is received, the system determines whether the GPS data is reliable."

Hmm, I wonder whether this would be a good for a popular article on an introduction to Kalman filtering?
