Beware of the leap-second bug. I don't have a BU 303, but all the other SiRF units I've tried are off by a second for some strange pattern. http://www.megapathdsl.net/~hmurray/ntp/leap-gps.gif That happens when a leap-second is pending. >I know my position to within 10m (got from a roof reading with 9 sats >in view) so my confidence in the readings is high. > >I only need accuracy to about half a second but then need that machine >to be the stratum 1 server for the other machines in the environment. >For reasons I won''t bore you with they can't connect to an external >network connection so this seems the best solution? In theory, one satellite should be good enough if you know your location. That only works if the software in the GPS box supports that mode. -- These are my opinions, not necessarily my employer's.
