Good point about WAAS.   I wonder if newer timing receivers that support WAAS would continue to function in a stationary mode if they could only receive valid signals from WAAS ?   I also wonder if the WAAS ground segment would continue to function without GPS ?   That being said the transmitters are already in orbit.

(Ie. a transmitter on a geo stationary sattelite that could emulate enough of the gps signals to allow statioanry timing receivers to function.)
