On a Thunderbolt, you can only manually enter your position with using single-precision floating point numbers... not really accurate enough for a time-nut. When Lady Heather does a precision survey, it stores the high-prescision results of the 48-hour survey by doing repeated single-point survey commands until one just happens to be within one foot of the desired position. Quite a kludge, but we are time-nuts. Also, the Thunderbolt does not have a user-controllable Kalman filter setting, so that option is grayed out.
---------------- You can let the GPS receiver do a self-survey but you can also enter the location that you determined by other means. _______________________________________________ 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.
