Hi Guys,
I feel like I missed “The Big Thing” in time keeping land. I should have watched my Ublox LEA-5T. What is the difference if it is in the reporting mode for GPS or UTC time? If they skip a second UTC, surely the GPS time isn’t run incorrectly forever. I’m using the Ublox to synchronise a micro that is clocked with the 10Mz signal from and Rb module, and the micro controller keeps time from there. So I currently wouldn’t see a leap second unless I looked back at the GPS. Another idea I had since making a copper thermal mass for the Rb module… A microcontroller clocked with the Rb module should be able to tell the temperature by counting the frequency of any other crystal generated clock in the circuit.. not necessarily just for the Rb thermal mass, but outside environment. Although the temperature has some effect on the Rb module frequency, it is less then the effect on Xtal frequency. Cheers, Brek. ps. am I replying the way I’m supposed to with a new email and subject? _______________________________________________ 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.
