Wonder how feasible it would be to have a single GPS+GLONASS+Galileo chip that automatically feeds you the service(s) with the best signal; without murdering your battery?

There are already chips that combine the results from GPS and GLONASS. Because it moves from 31 satellites to about 50, time to get a fix is improved (since it might see 4 GPS satellites and 2 GLONASS ones more easily) and accuracy is better.
