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.

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.
