Question

V1Jays on Twitter asked:

Will the increase in GPS technology mean more satellites in the sky in the coming few years or the existing setup enough?

Answer

More people using GPS won't require more satellites, just like more radio listeners doesn't mean you need more radio transmitters, or more bums on seats in an auditorium doesn't mean you need more members in an orchestra.  However, there will soon be more positioning systems, when the Galileo constellation launches.  Galileo is an EU/ESA project to enhance and back up GPS.
