So the decision makers think that after a solar flare or "some other reason" (hostile destruction of the birds, perhaps?) takes out the GPS system, it'll be back up and running within six days? That sounds optimistic to me. It sounds to me more like you would need to function indefinitely without GPS, and just use GPS for initial position survey and as a convenient way to synchronize to external time reference (with ground-based backup methods in place and periodically tested). _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
