A little of both. The desire on the customer's part (i.e., what the US military wanted) was accurate rapidly updatable location information. But the approach used for GPS also required the receiver to precisely compute the time as well. So, it wasn't in the requirements, but it is inherent in the design. -John -- John Maxwell KB3VLL j...@jmaxhome.com _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
