Ublox indicate in the product info sheets that the TCXO option is used to get to a first fix quicker in weak signal conditions. It is not specified and I think that it is logical, that there is an improved timing solution. I would expect that both XO and TCXO versions are the same frequency and the better long term stability of a TCXO not be an influence on the single shot quantization error of the 1PPS. > _____________________________ > 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.
