With Selective Availability enabled would that cause time accuracy
issues with the signals from the satellite?
I believe that it would inject a maximum of about 300 ns of random
error. However, SA is obsolete. The newest satellites don't even
implement it.

Hi,
I am trying to setup gpsd + ntpd with NanoBSD for binary mode of the GPS (a
Rockwell Jupiter TU30-D140-221).
Both gpsd and ntpd are installed from FreeBSD 7.3 packages.
gpsd is version 2.90 and ntpd is version 4.2.4p5.
gpsd is up and running and xgps from another computer is receiving the

John,
My experience with SA some years ago was that the timing accuracy was in
the order of LORAN C, that is, about one microsecond. However, the
oscillator in my Austron 2201 GPS receiver was disciplined in frequency
by LORAN C, with result the timing accuracy was in the order of 50 ns. I

You need to build ntpd (or the whole port) with REFCLOCK and CLOCK_SHM
defined.
but still, if I do 'make config', I only see three options; NTPSNMPD,
RAWDCF SSL.
