1 - Introduction
1.1 - Overview
The GPS6000-PRO accurately synchronises your time server with
international atomic standards. Incorporating the latest in GNSS
technology and multi-constellation support (GPS/GLONASS/Galileo
ready), the GPS6000-PRO ensures accurate and reliable time on
your systems, even in hostile RF environments.
With 32 satellite parallel tracking and class-leading high performance
design, the GNSS decoder supplies time data accurate to within 30
nsec of UTC. The user programmable cable delay compensation
ensures timing accuracy is maintained, even over long cable runs.
The system has been engineered to ensure reliable performance. The
high sensitivity GPS6000 decoder allows for operation in the most
demanding weak signal and hostile RF environments. The GPS6000
fully integrates with your time server, providing real time diagnostics
and active antenna monitoring. Advanced anti-jam technology and
multi-constellation support further increase system reliability.
Installing the GPS6000 is simple. All cables are supplied pre-
terminated. The GPS6000 has also been purpose designed to allow
cost saving installation into your data centre, optionally connecting to
your time server via existing cat 5 structured cabling.

3 - Installing the GPS6000
Installing the GPS6000-PRO is a straightforward procedure. All cables
are supplied pre-terminated and no specialist tools are required.
However, to ensure reliable and safe operation, care should be taken
selecting appropriate locations for the GNSS antenna and lightning
arrester.
Please follow the installation guidelines below to ensure a trouble-free
installation.

3.2 - Installing the antenna
3.2.1 - Selecting an installation location
The antenna should be installed externally, with the maximum
possible sky visibility. For most installations, the ideal location will
be the roof of your building (the antenna is able to withstand extreme
temperatures, excessive vibration, rain, snow and sunlight).
Ideally, the antenna should have a clear uninterrupted 360º view of
the horizon. For installations where an unobstructed view of the sky
is not practical, the antenna should be installed with as large a view
as possible of the sky towards the equator. Installing the antenna
with a substantially reduced view of the sky will degrade system
performance and may increase synchronisation time.
3.2.2 - Mounting the antenna
The antenna should be mounted with the top of the dome facing
directly upwards and secured using the stainless steel surface mount
antenna bracket. Care should be taken to ensure the xings used (not
supplied) are suitable for the application. Figure 3.2 below details the
antenna mount xing dimensions.
Figure 3.2 - Antenna mount xing dimensions
3.2.3 - The antenna cable
The GPS6000-PRO is supplied as standard with an 8m (26ft)
pre-terminated RG-58C/U TNC to TNC coaxial cable for connection to
the lightning arrester. Longer antenna cables are optionally available
if required.

3.3 - Installing the lightning arrester
The multi-strike fast response lightning arrester connects between the
antenna and GNSS decoder. The lightning arrester provides surge
protection for the GNSS decoder (and attached systems) in the event
of a lightning strike.
PLEASE NOTE: THE LIGHTNING ARRESTER MUST NOT BE
INSTALLEDEXTERNALLY.
The lightning arrester should be installed internally at the point where
the antenna cable enters the building. It is important that the lightning
arrester is grounded to a low impedance ground system for proper
operation.
THE LIGHTNING ARRESTER IS SUPPLIED WITH A SEPARATE
INSTRUCTION SHEET WITH FULL INSTALLATION DETAILS.

3.4 - Installing the GNSS decoder
3.4.1 - Mounting the GNSS decoder
The GNSS decoder converts the raw satellite data into highly accurate
time information. The decoder should be installed internally, close to
the output of the lightning arrester (the system is supplied with a 1m
(3ft) pre-terminated coaxial cable for connection between the lightning
arrester and the GNSS decoder).
PLEASENOTE: THE GNSS DECODERIS NOT SUITABLE FOR
EXTERNALINSTALLATION.
The decoder should be secured in position using the integral surface
mounting brackets. Care should be taken to ensure the xings used
(not supplied) are suitable for the application. Figure 3.3 below details
the enclosure bracket xing dimensions.

3.4.2 - Cable connections
The connection between the lightning arrester and the GNSS decoder
should be made using the supplied 1m (3ft) pre-terminated RG-58C/U
TNC to SMA coaxial cable.
The system is supplied as standard with a pre-terminated 5m (16ft)
output cable for the connection between the GNSS decoder and
your time server. Longer cables are optionally available if required.
Alternatively, the output cable may be extended using Belden 9502
cable up to a maximum total length of 150m (492ft). Table 3.1 details
the cable colour scheme.

3.4.3 - Optional connection using structured cabling
To enable simple installation into a data centre or ofce complex,
the GNSS decoder may be connected to your time server using
category 5, category 5e or category 6 structured cabling.
Table 3.2 below details the suggested RJ45 / 8P8C pin connections.
Using this conguration, cable lengths of up to 300m (984ft) may be
used reliably.

3.5 - The cable delay offset
The GPS6000-PRO is capable of providing time data accurate to
within 30 nsec of UTC. At this level of accuracy, taking account of
cable lengths becomes critical. Every metre of cable between the
GNSS antenna and your time server causes an additional error of
approximately 5 nsec (see note over page). For long cable lengths,
this accumulated error can become very signicant.
The cable delay offset provides a simple solution to correct for errors
due to cable propagation delays. The total cable length between the
GNSS antenna and your time server is entered using the switch bank.
The GNSS decoder then automatically advances the time data by the
required offset to correct for the cable propagation delay.
GPS6000-PRO systems are supplied with the correct cable delay
offset value pre-programmed. For a typical installation, this preset
value should not need any adjustment. However, if required, the
cable delay offset can be programmed using the following guidelines.
3.5.1 - Programming the cable delay offset
PLEASENOTE:THEPRESETCABLEDELAYOFFSETSHOULD
NOTNORMALLYREQUIREANYADJUSTMENT.
The cable delay offset is programmed in metres using the cable
delay offset switch bank. The total cable length (in metres) should be
encoded in an 8 bit binary format and entered into the switch bank.
Switches set to on (the upper position) are summed. As shown in
gure 3.4 below, the left-hand switch is the most signicant bit (128m)
and the right-hand switch the least signicant digit (1m).
