GPS _will_ (can) not get a serious problem as long as the US is at war.

Buy a Glonass receiver. (In a few years buy a Galileo/Gagan/GPS/Glonass

The US has promised not to turn SA back on. I also do not think the
(maritime) DGPS stations have closed down in costal areas. They will
mitigate SA and still provide some integrity.
