During the recent attacks, there was a brief discussion as to whether the USG had or would invoke GPS SA. We have a client who is building a broad ATM network and had planned to use GPS based timing solutions from TrueTime for a clocking source, in addition to a feed from the LEC. If GPS SA is invoked down the road during a crisis, what effect is there, if any, on networks which rely on GPS for timing, not positioning?
