Hello Ragnar
Mktimetx uses the receiver-provided sawtooth correction in the TP message.
The TDEV plots in the presentation I linked show its effectiveness.

Current antenna placement was restricted by the 5m

Hello Peter
The aim of our study was to characterise the performance of single
frequency receivers for time-transfer. The F9P was a late addition to our
study and extending our software to dual frequency was too much work at the
time. Having a measured ionosphere was not such a huge improvement
Hello Anders,
Yes, we used TAPR TICCs do the testing. It’s a very economical solution
for testing multiple receivers in parallel.
The OpenTTP software mktimetx applies sawtooth corrections to the TIC
measurements, as you guessed. The corrected TIC measurements are combined
with the raw GNSS
Hi Michael, thanks for the reminder about your slides!
Your page 4 has the two setups. I think you are right in that the F9T
doesn't seem to take an external receiver clock (even if working with the
bare part, not the RCB-board).
(FWIW, AFAIK the not-so-low-cost septentrios use the left external
Hello Anders,
We did some work on single-frequency time-transfer with the F9P earlier
this year which we presented at IFCS-EFTF in April.

There's a paper too, which I should upload.
In short, the F9P is very suitable for code-based
