Scope
of
this
Chapter
This
chapter
describes
what
is
GPS
hub
site
synchronization
(GHSS),
and
how
to
implement
it.

Overview
GPS
Hub
Site
Synchronization
using
a
GPS
signal
(GHSS).
The
GPS
satellite
signal
acts
as
a
master,
and
each
collocated
RT
‐
A(HBS)
unit
that
receives
this
synchronization
signal
acts
as
an
HSS
Client
(HSC).
GHSS
works
differently
if
there
is
an
internal
GPS
capability:
•
RT

A(HBS)
units
based
on
the
RADWIN
2000
A+,
RADWIN
2000

or
RADWIN

require
additional
external
equipment
to
work
with
the
GPS

based
synchronization
sig
‐
nal.
•
RT
‐
A(HBS)
units
based
on
the
RADWIN
2000i
has
an
integrated
GPS
unit,
which
is
used
to
receive
this
GPS
‐
based
synchronization
signal.
