Although the Palisades driver has been extended to the Praecis, Thunderbolt
and Acutime the document at <
http://www.eecis.udel.edu/~mills/ntp/html/drivers/driver29.html> is silent
on what is now best practice for Trimble timing receivers.   Presumably PPS
was ignored because the event based timing packets yield reliable
sub-millisecond offsets.  The driver and document should be brought into
the PPS era and be renamed the TSIP refclock rather than Palisades.

Palisades/NMEA + ATOM is the way to use these receivers.
