The context for this query is that I'm looking for inexpensive GPS units with
a PPS output to connect up to ntpd.
Is anybody familiar with these units?
I just wired one up. The PPS signal is only 1 microsecond wide.
The PPS from my Z3801A is 10 microseconds wide. I can deal with that. The
extra factor of 10 is inconvenient. (at least so far)
The Garmin GPS 18 LVC has a command to adjust the PPS pulse width, but
that's at the granularity of 20 ms rather than the microsecond range. I just
scanned the SiRF binary protocol manual and NMEA manual and didn't see
anything. (But I might have missed it.)
These are my opinions, not necessarily my employer's. I hate spam.
