RoHS (Restriction of Hazardous Substances) complements the WEEE directive by banning the
presence of specific hazardous substances in the products at the design phase. The WEEE
directive covers all VERIPOS products imported into the EU as of August 13 2005. EU-based
manufacturers, distributors, retailers and importers are obliged to finance the costs of recovery
from municipal collection points, reuse, and recycling of specified percentages per the
requirements contained in the WEEE Directive.

Instructions for disposal of WEEE by users in the European Union.

Products which have the undernoted symbol located on either the product itself or its
packaging indicates that the product must not be disposed of with other waste. Instead, it is the
user’s responsibility to dispose of the product by handing it over to a designated collection point
for the recycling of WEEE.

The separate collection and recycling of your WEEE at the time of disposal will help to
conserve natural resources and ensure that it is recycled in a manner that protects human
health and the environment. For more information about recycling centres, please contact the
local city office, the household waste disposal service or the product supplier.

3. INSTALLATION

This section provides guidance on the installation of the LD7 receiver.
Contact your supplier or VERIPOS with questions or for advice when installing this

equipment.

3.1 LD7 SITING GUIDELINES

When choosing a location for the LD7 and variants the following requirements are
mandatory:

1. Ensure adequate ventilation for free air flow to the unit. This is important when working
in hot or humid regions.

2. Locate unit in areas free from excessive dust or smoke.

3. Avoid locations that experience excessive vibration.

4. Avoid exposure to high temperatures.

5. Shield the unit from direct sunlight.

6. Mount the unit securely to prevent movement.

7. Ensure there is easy access to front panel.

8. Ensure adequate access to the rear panel. Avoid mounting in a recess and have
sufficient slack to be left in cables (power, interfacing and coaxial) for LD7 unit to be
removed without disconnection.

9. All bends in coaxial cables to be maintained above minimum bend radius.

10. Use short tails of flexible coaxial cable (e.g. LMR 240) with appropriate converter
connections to connect antenna coaxial cables to the LD7. Support the antenna
coaxial cable weight to avoid stress being placed on the rear coaxial connectors.

3.1.1 Mounting

The LD7 is supplied with mounting brackets. These can be fitted to the top or bottom of the
receiver. This allows the receiver to be fixed to the top or underside of a shelf.

Page 27

3.1.2 Ventilation Requirements

The LD7 needs 15–25 mm minimum clearance all round, to allow a flow of air.

LD7 Ventilation

3.2 ANTENNA INSTALLATION
This section provides general guidance on installation of antennas and cabling when

installing the LD7 receiver.
It is very important to the on-going performance of your system that a high quality

installation is performed. This will ensure optimum performance and reliability.

After equipment installation it is recommended that a calibration survey is carried out to
compute any heading C-O and GNSS offsets for the Main GNSS antenna. Antenna offsets
and C-O values should be entered within the navigation or DP software.

3.2.1 GNSS / L -Band Antenna

The GNSS / L-Band antenna receives transmissions from GPS, GLONASS and L-Band
communication satellites (used for VERIPOS Correction Signals).

This section describes best practice when positioning and installing your GNSS / L-Band
antennas.

For more details please refer to VERIPOS document “Antenna & Coaxial Cable Installation
Guide” provided as part of the installation documentation.

3.2.1.1 General

The GNSS/ L-Band antenna is used for vessel positioning and therefore its mounting
location is of high importance to the system.

It should be mounted with a clear view of the sky in both the horizontal and vertical
directions.

If the antenna does not have a full view of the sky there will be times when signals will be
blocked, resulting in degraded performance of the system.

Good Installation – Antenna at Top of Mast with Good Spacing

During installation observe the following guidelines:
 Offsets to the GPS antennas must be measured by a competent person to ensure no

errors are introduced to the DP, Survey or Navigation systems.

 Care must be taken to ensure that antennas are not installed in the direct path of

Radar transmissions, Inmarsat-B Dome transmissions, VSAT transmissions or high
power HF whip/wire antenna.

Good Installation – Antenna at Top of Mast with Good Spacing

If antennas cannot be installed directly at the top of the mast/ships structure, it is essential
that the mounting point is sufficiently strong for this purpose. Arrangements must be able to
withstand vibration and wind.

Alternatively a pole can be used with a 5/8"x11 UNC threaded end (standard marine

mount). The pole can be attached by welding or using “U” clamps as above. This method

allows the GNSS/GPS antenna to be mounted without the need for the bracket. Ensure that
grease is applied to the threads when installing the antenna.

Fit the antenna to the bracket and clamp the bracket to the mounting pole or the mast using
“U”-bolts. When mounting the antenna on an extension pole fit the antenna to the pole first
for ease of handling at height.

Antenna with extension pole

If the threaded pole is already installed up the mast, use a small length of coaxial cable
attached to the N-type connector as a safety lanyard for the antenna.

Carefully connect the coaxial cable following manufacturers’ guidelines.
Form cable below the antenna into a small loop, approximately 150–220 mm (6 to 8in) in

diameter. Attach the loop to the mounting pole under the antenna to provide strain relief
from the cable.

For more detailed guidance please refer to the VERIPOS document “Antenna and Coaxial

Cable Installation Guide”.

3.2.2 Antenna Placement for GNSS Heading

Careful consideration of the placement of the Main and Auxiliary antennas is required to
maximise the LD7’s GNSS headlining accuracy.

3.2.2.1 Antenna Separation
The GNSS heading solution accuracy is largely determined by the distance (or baseline)

between the Main and Auxiliary antennas. The larger the baseline, the better the heading
precision will be.

The table below details the expected GNSS heading precision in relation to the baseline:

Baseline

GNSS Heading Precision

1m

0.3°

3m

0.1°

10m

0.03°

VERIPOS recommend a minimum baseline of 2m.

3.2.2.2 Antenna Orientation & Height

The LD7 GNSS heading is computed from the Main to the Auxiliary antenna as illustrated
below:

GNSS Heading Solution Direction

Procedure Title:

LD7 Installation Manual

File Ref.:

AB-V-MA-00559

Rev No:

Page 31

Assuming the antennas are mounted along the vessel Fwd/Aft centreline, with the Aux
being the furthest forward antenna, the GNSS heading would correctly reflect the vessel’s
heading. In the below example, no heading correction would need to be applied in the
navigation system software:

In the next example, the Main and Auxiliary antennas are installed perpendicular to vessel
North with the Main antenna at the Starboard side and the Auxiliary antenna at the Port
side. A correction (C-O) of +90° would be required in the navigation system software to
align the GNSS heading to vessel North.

The above examples are simplified for illustration purposes. To achieve the heading
accuracies specified a gyro calibration should be conducted.

The Main and Auxiliary antenna should also be installed at similar heights to ensure
consistent heading. If this is not done the heading solution will be noisy due to each
antenna being subject to different amounts of vessel motion e.g. vessel roll.

3.3 COAXIAL CABLE INSTALLATION

VERIPOS recommend and supply pre-terminated LMR coaxial cables as they give the best
performance in permanent installations.

Label each cable carefully at top and bottom identifying the antenna attached.

3.3.1 Maximum recommended cable lengths

The signals received by the antennas will deteriorate at different rates as they are
transmitted through coaxial cable. As a result VERIPOS recommend a maximum cable
length.

The following table details the maximum length for each signal type.

3.3.2 General

VERIPOS recommended cable for the antenna runs is LMR 400.
Terminated tails of LMR 240 are used at either end for ease of attachment to hardware.

Page 33

When running multiple coaxial cables VERIPOS recommend labelling to ensure cables are
attached to the correct antennas and equipment.

Survey the route of the antenna cabling to ensure:

1. The total length of the cable run does not exceed the supplied cable length for this
installation. Contact your supplier or VERIPOS if this is the case.

2. The cable does not cross or run parallel with any single phase or three phase mains
cable (110 VAC, 220 VAC or 440 VAC) or any high power RF cables leading to
transmitting devices such as Inmarsat B and VSAT domes.

3. The cable avoids fluorescent lights.

4. A support wire is used where the cable run has to cross a free space and does not
rely solely on cable ties for support.

5. Sufficient space is available in the selected cable entry through the bulk head for the
connectors to pass through without damage. If the connector cannot pass through the
cable entry it may be necessary to cut the connector off and re-terminate once the cable
has been passed through.

6. The cable is not pinched.

7. The route is free from all burrs or sharp edges that could damage the cable jacket.

8. All connectors and couplers are properly sealed from the environment with self-
amalgamating tape and electrical tape.

9. Stress loops are fitted to prevent excess force on the connectors, in particular the
antenna connectors.

10. The minimum bend radius for the cable is not exceeded.

Once cables are in place seal all connections with self-amalgamating tape for
protection against the marine environment.

This section details the antenna connections made to the LD7 IMU.

3.4.1 Coaxial cables to antennas

3.4.1.1 Standard LD7 Variant
Two antenna connections (Main and Auxiliary) are required to obtain a GNSS heading

solution.
These are shown below;

LD7 Rear Panel Antenna Connections

If a GNSS heading solution is not required, the LD7 can provide VERIPOS position
solutions with just the Main antenna connection. On a standard LD7, the Main antenna

3.4.1.2 LD7 Mod 1 Variant – Dedicated L-Band Input
The LD7 can be supplied with a dedicated L-Band antenna input if required. This is useful

on installations where the optimum location for the GNSS antennas may not be the
optimum location for L-Band reception.

An LD7 Mod 1 unit will therefore have three antenna inputs. The Main antenna will be the
main GNSS input however will no longer be used for L-Band.

The function of the Auxiliary antenna input remains unchanged and is used a secondary
GNSS input for GNSS heading.

There will be a dedicated coaxial connector (TNC) installed on the front of the LD7 which
will be used only to receive L-Band correction data using a dedicated L-Band antenna e.g.
V86 antenna.

3.5.4 Ethernet interface

The LD7 is configured via Web Interface. The Ethernet RJ45 connector on the LD7 rear
panel can be connected directly to a PC with Ethernet port.

The default IP address used to access the Web Interface is 192.168.0.126. This can be
changed if required.

The Ethernet interface can also be used to output any data which is available via serial
port. When outputting data via Ethernet, the IP address and the data source must be used,
NOT the IP address of the LD7. For example, to output NMEA position or Heading data,
the GNSS card IP address must be used. To output RTCM correction data, the L-Band
card IP address must be used.

The default IP addresses are as follows:

LD7 default IP address: 192.168.0.126
GNSS card default IP address: 192.168.0.127
L-Band card default IP address: 192.168.0.128
