Chapter 12: GPS Hub Site
Synchronization
12.1 Scope of this Chapter
This chapter describes what is GPS hub site synchronization (GHSS), and how to implement it.
12.2 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 C+, or RADWIN 2000 D+
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.
12.3 GHSS for the RADWIN 2000 A+,
RADWIN 2000 C+, or RADWIN 2000 D+
GHSS for the RADWIN 2000i is covered in GHSS for the RADWIN 2000i on page
To implement GHSS for the RADWIN 2000 A+, RADWIN 2000 C+, or RADWIN 2000 D+, the
following additional equipment is required:
•
GPS Synchronization Unit (GSU) kit
•
IDU‐H
•
HSS Unit
