1 Introduction
1.6 LD8 Notices
The following notices apply to the LD8:
1.6.1 Waste electrical and electronic equipment
The Waste Electrical and Electronic Equipment Directive (hereinafter referred to as the “WEEE
directive”) places an obligation on EU-based manufacturers, distributors, retailers and importers to take-
back electronics products at the end of their useful life. A sister directive, 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
symbol shown below is on the product or on its packaging, which indicates that this product must not be
disposed of with other waste. Instead, it is the user’s responsibility to dispose of their waste equipment by
handing it over to a designated collection point for the recycling of waste electrical and electronic
equipment.
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.

This section provides guidance on the installation of the LD8 receiver. In the event of difficulty contact
your supplier or VERIPOS (https://help.veripos.com).
3.1 LD8 schematic example
The schematic shown below is one example of an antenna setup arrangement. Please be aware that
other antenna configurations are possible. For long-term installations, always contact VERIPOS to
obtain setup drawings specific to your installation, as these may differ from the example below.
16
LD8 Installation Manual

3 LD8 installation
3.2 Location guidelines
When choosing installation locations, the following requirements should be taken under consideration:
1. Ensure adequate ventilation for free air flow to the main unit. This is especially important when
working in hot or humid conditions. See section Ventilation Requirements for more details.
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 the interface panel.
8. Avoid mounting the receiver in confined spaces. Ensure sufficient slack remains in unit cabling to
allow the rear of the unit to allow easy access.
9. Ensure all bends in coaxial cables are maintained above minimum bend radiuses.
10. Use short tails of flexible coaxial cable (e.g. LMR-240). Ensure sufficient strain relief on the main
antenna coaxial to avoid stress being placed on coaxial connectors.
3.3 Mounting
NOTE
Before mounting the LD8 take a note of the system serial number, which typically
starts with 'NMPL' and which can be found on the underside of the unit. This will be
required for logging into the system, as covered in the LD8 Operations Manual.
Mount the LD8 on a secure, stable surface. The unit can be secured via four M5 mounting holes (imperial
size #10), as shown in the figure below. Take care not to overtighten as this will result in damage to the
housing. Note that the torque of the screws should not exceed 15 inch-lb.
17
LD8 Installation Manual

3 LD8 installation
3.4 Ventilation requirements
The LD8 needs 15-25mm clearance all-round to allow an adequate flow of air:
3.5 Antenna installation
This section provides general guidance on installation of antennas and cabling.
It is very important to the on-going performance of your system that a high-quality installation is
performed, as this will ensure optimum performance and reliability.
NOTE
After equipment installation it is recommended that a calibration survey is carried
out to compute the heading offset (also referred to a C-O) and the position offset
(Primary GNSS antenna). The position offset and heading offset should be entered
within the navigation or DP software.
3.5.1 GNSS / L-band antenna installation guidelines
The GNSS antenna receives both multi-constellation and L-band communication satellites (used for
VERIPOS Correction Signals).
This section describes best practice when positioning and installing your GNSS antenna/s.
For more details please refer to VERIPOS document Antenna and Coaxial Cable Installation provided as
part of the installation documentation.
Antennas should be located with a clear 360° view of the sky. The best way to ensure this is to mount the
antenna at the highest possible location. If the GNSS antenna does not have good satellite visibility,
there will be times when system performance is degraded.
18
LD8 Installation Manual

3 LD8 installation
Examples of good installations – Antennas placed at top of mast with good spacing
During installation observe the following guidelines:
lOffsets to the GNSS antennas must be measured carefully to ensure that no errors are introduced
to the DP, Survey or Navigation systems.
lCare must be taken to ensure that antennas are not installed in the direct path of transmissions
from vessel radar, Inmarsat systems, VSAT systems or high-power HF (whip/wire antennas).
lIf the antennas cannot be installed directly at the top of the vessel mast or structure, it is essential
that the mounting point is sufficiently strong for this purpose. The installation must be able to
withstand vibration and wind over a period of many years of operation.
lStainless steel brackets and mounts are recommended to mitigate the effects of saltwater
corrosion.
lA mounting pole can be used with a 5/8"x11 UNC threaded end (standard marine mount). The
pole can be attached by welding, or by using “U” clamps as above. This method allows the
antenna to be mounted without the need for a bracket.
lEnsure that grease (such as copper slip) is applied to the threads when installing the antenna.
lFit the antenna to the bracket and clamp the bracket to the mounting pole or the mast by using U-
clamps. When mounting the antenna on an extension pole, fit the antenna to the pole first for ease
of handling at height.
lIf 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.
lCarefully connect the coaxial cable following manufacturers’ guidelines. Form cable below the
antenna into a small loop, approximately 150–220 mm (6 to 8 inch) in diameter.
lAttach 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.

3.5.2 Placement for heading antennas
Careful consideration for the placement of the primary and secondary antennas is required to maximise
the LD8 GNSS heading accuracy.
3.5.2.1 Antenna separation
The GNSS heading solution accuracy is largely determined by the distance (or baseline) between the
primary and secondary antennas. The larger the baseline, the better the heading precision will be.
The table below details the GNSS heading precision, which relate to the antenna separation baseline.
VERIPOS recommend a minimum baseline of 2m.
Baseline Static GNSS Heading Precision
2m 0.08°
4m 0.05°
10m 0.02°
3.5.2.2 Antenna orientation and height
The heading direction is computed from ANT 1 to ANT 2 as illustrated below:
