Newer navigation units offer 5Hz output, combined with SBAS (WAAS in the US/Canada) for a more accurate measurement, you should be able to do a "modest" survey in a few minutes. I believe the accuracy continues to improve as survey time increases, up to a few hours. -Michael _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
