Look at the bottom of this page refclock.htm
<http://doc.ntp.org/4.1.0/refclock.htm> for a list a clocks that NTP can
use.  Some of them are GPS receivers.  For example "type 30" is the Oncore
 line of receivers and Type 20 is any generic NMEA GPS receiver, with is by
far the most common type.

There is nothing special about configuring a Soekis.  It is just like any
other system that runs ntpd.  The top of the documentation pages is here
