As far as I'm concerned anything that you can do to improve the position accuracy, environmental changes, noise environment, etc is a good thing. Minimizing errors and disturbances can't hurt and may even improve things. How much any improvement provides ... ??? But time nuts tend to be a bit nutty about minimizing our therbligs ;-)
Most receiver self-surveys seem to get your lat/lon to the 2-3 meter range. Heather's median survey is in the 1-2 meter range. PPP data is in the < 0.25 meter range... seems like something worthwhile. (altitude errors are usually around twice the lat/lon error). There is always the possibility that some receiver model's computation of lat/lon/alt could have some intrinsic bias in it. If so, a position calculated by an external source could possibly degrade performance... ---------------- > Is this applicable to a Thunderbolt, and would this improved position accuracy be expected to improve the time accuracy from a Thunderbolt compared to using the older Lady Heather 24 hour self survey method? _______________________________________________ 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.
