SNTP is defined in the NTPv4 draft in
http://www.ietf.org/internet-drafts/draft-ietf-ntp-ntpv4-proto-09.txt in
section 14. You can also look at RFC 4330 but that's about to be
obsoleted by the NTPv4 draft. SNTP is *not* a client protocol.

Since it hads a GPS receiver in it, it only needs the SNTP part of the
spec and be an SNTP server. See the NTPv4 draft.
