Introduction
Welcome to the Artemis Mk6 Installer’s Guide. It explains how to install the Artemis
control software onto a Type 3 Marine Processor or other type of computer, and how
to use it to configure the Artemis system.
For instructions on how to use Artemis, please see the Artemis Mk6 Operator’s Guide
(Doc No. 94-0440-4).
The System Overview on page 6 provides an introduction to the Artemis system.
The System Layout section on page 8 describes possible arrangements of the
system on board a vessel. Installing the Sensors on page 12 takes you through the
installation of the Mobile Station, Fixed Station and Beacon, as appropriate.
The Installing the Control PC section on page 27 gives information for mounting
a Marine Processor supplied by Guidance Marine and how to upgrade the Artemis
control software, if required.
The Configuring the Artemis System section on page 30 explains how to configure
the system for your vessel.
5

The Artemis microwave-based position reference system provides accurate positional data to
marine DP (dynamic positioning) control systems. It enables automated approach and station
keeping relative to a rig or platform, or to another vessel.
The standard Artemis system consists of:
• Two identical Antenna Units (or Sensors), user-configurable as a Mobile Station and a
Fixed Station.
• The Artemis Control PC, a Windows-based marine specification computer, running the control
software.
• Artemis Client PC(s), optional computers used where more than one installation of the Artemis
Dashboard software is required.
• Hand-held Operating Panel (or Pendant).
An alternative configuration - the Beacon system - involves the same components as the standard
system except for a Beacon Unit instead of a Fixed Station. A Beacon Unit does not provide an
Azimuth measurement.
Antenna Units
The Mobile Station is mounted on the DP-Equipped vessel, ideally at the top of the main mast.
The Fixed Station is installed on a fixed platform if absolute positioning is needed or on a moving
platform or structure to provide relative positioning.
Hand-held Operating Panel (Pendant)
A hand-held unit that can be connected to a station or Beacon unit to read and set system
parameters during installation. It can also be used to view positional data once the system is in
operation. This is an optional diagnostic aid.
System Overview
Artemis Control Software
The following applications run on the Artemis Control PC, usually mounted on the bridge near to
the controls of the vessel’s DP system:
• Manager – This Windows service running on the Artemis Control PC can be configured to run
automatically after the PC powers up. It provides a single point of control for an Artemis sensor
through which the other components communicate.
• Service Interface – Used for system installation and maintenance, it allows network
communications to be configured and parameters on an Artemis Station to be viewed and set. It
displays the state of connected Artemis Dashboard(s) and can be used to take basic control of the
station.
• Dashboard – Used to control and monitor normal system operation. Up to five instances of the
Dashboard can run simultaneously on the Control PC and Client PCs, but only one of these can
exercise control at any given time; the others can only be used to monitor the system.
An Antenna Unit (Mobile or Fixed Station) An Operating Panel
Artemis Service Interface Artemis Dashboard
Explosion-Proof Antenna Unit/Beacon
An antenna unit or beacon can be made safe for operation in hazardous zone 2 conditions with
the use of a pressurisation unit. This forces clean air into the housing of the antenna unit or beacon
to prevent the ingress of explosive or flammable gases that might otherwise be ignited by electrical
sparks. Contact Guidance Marine for details.

System Overview (Continued)
System Operation
In order to provide positional data to the vessel’s DP system, the Artemis system needs to be
“locked”. In this state, the antennae of the Fixed and Mobile Stations are facing each other and
automatically tracking by maintaining a continuous microwave link.
The distance between the sensors is obtained from the travel time of the microwave signal,
measured by means of coded interruptions in the continuous wave. The bearing of the Fixed
Station, with respect to the centre line of the vessel, is measured using a precision shaft encoder.
The Fixed Station measures the Azimuth and reports it to the Mobile Station. The Azimuth is the
horizontal angle between a reference direction and the Mobile Station, with its vertex at the Fixed
Station.
Beacon Unit
Used instead of a standard rotating Fixed Station on a fixed platform for absolute positioning, or
on a moving platform or structure for relative positioning. The antenna of a Beacon unit does not
rotate, and three types of antenna are available for different situations:
A. Omni directional antenna with 360° beam width
B. Semi-omni antenna with waveguide, 100° beam width
C. Horn antenna with 66° beam width

The beam width of an antenna unit (Fixed or Mobile Station) is approximately 2°.

Installing the Sensors
This section explains how to install the Artemis sensors and contains the following pages:
• General Considerations (page 13)
• Dimensions of Base Unit (page 14)
• External Connections to an Artemis Sensor (page 15)
• Installing a Mobile Station (page 16)
• Installing a Fixed Station (page 19)

General Considerations
Mounting Template
A U-shaped bracket suitable for mounting the sensor should have the dimensions shown on the
right.
Sensor Orientation
Where possible the sensor should be mounted on the centre line of the vessel. It is recommended
that the centre connector and the rear mounting point be on - or parallel to - the centre line of the
vessel (see below).
Sensor Clearance
To facilitate 360° antenna rotation, a cylindrical space of 1400mm diameter with a vertical depth of
300mm around the centre of the rotating antenna should be free from any obstructions.
Sensor on - or
parallel to - the
vessel centre line

type to the other.
15

Site Requirements
When choosing a location for the Mobile Station:
• Avoid objects like masts, poles or even bigger structures in the direct vicinity or in front of the
antenna; the Artemis positioning system requires free line of sight between the antennas of
the two stations.
• Avoid mounting the antenna unit in a position in which its antenna is in the same horizontal
plane as the ship’s radar antenna.
For permanent installations the ideal mounting position is on top of the vessel’s main mast. It is
advised to fit a small platform directly under the mounting bracket to ease installation and service.
The distance between the platform and the mounting bracket should be at least 0.8 m to be able
to remove the bottom cover from the antenna unit.
For temporary installations other mounting positions can be considered.
If the system is used at short ranges, the Mobile Station and the Fixed Station or Beacon should
be at roughly the same height. An exception here is a Beacon with a horn antenna. Since the
horn antenna is looking down by 30°, the Beacon may be in a substantially higher position than a
Mobile Station.
!Do not mount the antenna unit too close to the mast. The antenna must be able to turn around freely without bouncing off the mast or other obstacles.
Mounting the Mobile Station
!Take measures to prevent falling down from the mast or other heights. Use a safety harness.
The antenna unit should be mounted:
• On a torsion-free stand or bracket.
• In a position where the antenna has preferably 360° around free line of sight.
The antenna unit can be mounted in a ’U’-shaped bracket with three holes. The U-shape allows
the unit to be slid in the bracket, rather than lowering it from above. In this way it takes less effort
to install the antenna unit.
See General Considerations on page 13 for the dimensions of a ‘U’-shaped mounting
bracket.
Installing a Mobile Station
!To avoid damage to the antenna it is strongly recommended to mount the antenna unit in its bracket without the antenna, and mount the antenna afterwards.
To mount the antenna unit in the bracket.
1. Slide the antenna unit in the mounting bracket.
Note: There is only one position in which the antenna unit fits in the bracket. This is the position
where the connectors are facing when standing in front of the ’U’-shaped cut-out of the bracket.
2. Mount the antenna unit with three M8 bolts. Place a washer between the bolts’ head and
the mounting brackets of the unit. Use spring washers to secure the nuts. Preferably use
stainless steel bolts, washers and nuts.
To Mount the antenna unit:
3. Position the antenna such, that the red mark on the antenna shaft of the antenna unit and the
red mark on the flange of the antenna are aligned.
16

Installing a Mobile Station (Continued)
4. Mount the antenna with the six self-retaining M6 hexagon socket-head screws of the
antenna, using a 5 mm hexagon key.
!Tightening the bolts if the antenna has not been properly positioned will damage the
antenna flange of the antenna unit.
Closing the Vent
To avoid water from entering the antenna unit, the vent must be closed. This is done by turning
the ventilation screw clockwise and tightening it with a 5 mm hexagon key.
Connecting the Antenna Unit
See External Connections to an Atemis Sensor on page 15
Aligning the Mobile Antenna
The direction of the antenna mounted on the antenna unit is defined by the position of the main
shaft of the antenna unit. Directly coupled to this main shaft is a precision shaft encoder which
measures the actual position (angle) of the main shaft. The angle measured by the encoder should
be related to a reference direction. To compute the vessel’s heading from the angle of the Mobile
antenna (the relative Mobile antenna bearing) and the azimuth as received from the Fixed Station,
the Mobile antenna must be aligned with the centre line of the vessel.
If the Mobile Station is mounted at the centre line of the vessel, the bow or the stern can be used
for alignment. The best alignment will be obtained when the reference object is far away. If the
Mobile Station is installed off the vessel’s centre line, the antenna must be aligned parallel to the
centre line. In this case a reference mark must be defined (see below).
For the alignment the optional telescope is recommended. It is assumed that the station has been
configured as a Mobile Station.
To align the Mobile antenna:
1. If available, install the telescope on top of the antenna (see below).

Installing a Mobile Station (Continued)
2. Connect the operating panel to the antenna unit.
3. Switch the power to the Artemis Mobile station on and allow about 60 seconds for the station
to start up.
4. Press Menu 1 (Operate) on the operating panel.
5. Turn the antenna roughly to the reference mark by making use of the ◄and ►keys and the
0 key (to stop the antenna turning) of the operating panel.
Note: The rotational speed can be increased by pressing the ◄or ►key twice in quick
succession. This works only if the antenna is already turning.
6. Press Menu 263 on the operating panel; the following display page appears:
7. Press Enter; the “<” starts blinking. Using the ▲▼ keys, select the value OPEN LOOP and
press Enter to confirm.
8. Turn the antenna gently by hand until the telescope’s vertical hairline is aligned with the
reference mark.
!Do not try to force the antenna by hand if it cannot be turned easily. This may damage the
antenna and/or the turning mechanism. The antenna can only be turned by hand if the
servo control mode is “OPEN LOOP” or if the operating mode (Menu 262) is IDL (idle) or STB
(standby). In Configuration mode (Menu 5) the operating mode of the antenna unit is STB
(standby) by default.
9. Press Menu 231 on the operating panel; the following display page appears:
10. Press Enter; the cursor starts blinking.
11. Enter the bearing reference:
• ’0’ if the antenna is aimed at the bow or at a reference mark near the bow of the vessel;
• ‘180’ if the antenna is aimed at the stern or at a reference mark near the stern of the vessel.
12. Press Enter; the bearing reference has now been set.
13. Press Menu 263 (Servo Control).
14. Press Enter; the “<” starts blinking. Using the ▲▼ keys, select the value NORMAL for the servo
control mode and press Enter to confirm.
15. Press Menu; the Main Menu Mobile appears.
16. Disconnect the operating panel and replace the socket cap.
17. Remove the telescope from the antenna and store it in a safe place.
All other settings can be entered from the Artemis Service Interface running on the Control PC. If
this PC is not (yet) available, these settings can also be entered from the operating panel.
18

Installing a Fixed Station
Site Requirements
When choosing a location for the Fixed Station:
• Avoid objects like poles or structures in the direct vicinity or in front of the antenna. Artemis
requires line of sight between the antenna of the Fixed Station and the antenna of the Mobile
Station.
• Avoid a relatively large land path in front of the Fixed Station.
Do not mount the antenna unit too close to any obstacles. The antenna must preferably be able
to turn around freely without striking obstacles, which may damage the antenna. However, if
the antenna cannot turn 360° around but can make a large enough sector to cover the work
area, physical limits can be set to avoid contact with obstacles. These limits can be set with the
operating panel. See Setting Station Parameters with the Operating Panel on page 21 for
details.
!The standard Artemis MK6 Fixed Station may not be installed in an explosion hazardous environment. For operation in a zone 2 hazardous environment, an
optional pressurisation unit is available.
Inuence of Antenna Heights
When choosing the height at which the Fixed Station is installed, the following aspects have to be
considered:
• The influence of the curvature of the earth when operating the system at long ranges. This is
called the radio horizon. This influence tends not to be important for the Artemis Mk6 system
because the maximum range of the system is generally less than the radio horizon, even with
low antenna positions.
• Reflection of the microwaves off the surface of the water may cause interference with the
direct signal. This can cause weakening or extinguishing of the signal. The positions at which
this phenomenon is experienced are generally referred to as ’range holes’, ’dip zones’ or
’interference zones’
The position and width of these interference zones are dependent on:
• The antenna heights.
• The wavelength of the transmitted signal.
The strength of the interference depends on the distance between the transmitting and receiving
antenna and the nature of the water surface. A smooth surface reflects the signal better than a
choppy surface. The signal at the receiving antenna in the diagram below is extinguished when
D1 + D2 – D = n λ, where:
Reflection of microwaves against the water surface
D1 + D2 = indirect path length.
D = direct path length.
n = 1, 2, 3, …..
λ= wavelength.
Computer calculations show that the major interference zones are out of range of the Artemis
system. They fall at a distance over 5 kilometres. Nevertheless, a general rule is that lower Fixed
and Mobile Station positions are in favour, because:
• The interference zones fall closer and hence are easier to overcome because the signal
strength is still relatively high.
• The interference zones are smaller than for higher antenna positions.
19

Operation of more systems in the same area
Operation of more than one system in the same area is possible in the following situations:
• Vessels have their own work sector and are not ’crossing’ each other. See below.
• Vessels work in the same direction, but with different frequency pairs. See right.
In the diagram below, the beam sectors do not come within 10° of each other and no interference
will occur.

In the diagram to the right, the best combination of frequency pairs is pair 0 for system 1 and pair
1 for system 2, while these pairs give the largest difference between the frequencies of the Mobile
Stations.
To avoid influencing each other, the two Fixed Stations should be located at least two metres from
each other in the vertical plane and no more than six metres apart in the horizontal plane. The best
position for two Fixed Stations working in the same direction is above each other with at least two
metres difference in height.
