For those new to GPS, or interested in the technology behind it, here's a useful article: <A HREF="http://www.utexas.edu/depts/grg/gcraft/notes/gps/gps.html">Global Positioning System Overview </A> I was surprised by the section quoted below, which shows the non-degraded accuracy to be considerably less than the centimeters-level I have heard many claim. Is there a scheduled date on which Selective Availability degradation will be ended, and will all small GPS receivers then attain greater accuracy? Thanks, Jim ----------------------------- Precise Positioning Service (PPS) •Authorized users with cryptographic equipment and keys and specially equipped receivers use the Precise Positioning System.
