The longest range local position reference sensor in the market today • Operating range up to 5km • All weather operation • Overcomes GNSS scintillation • Automatic beacon and sensor acquisition • Guidance Marine Dashboard control • Stations and beacons compatible with legacy Mk4 systems Artemis Mk5 is a microwave position reference system for use in long range marine Dynamic Positioning (DP) applications. Artemis accurately measures the range and bearing of a mobile asset relative to a fixed position. The position is determined by measuring the absolute distance and the relative angle between two Artemis stations. The longest range microwave reference sensor in the market today, Artemis’ technology is proven in the offshore operating of offloading and transportation of oil between shuttle tankers and FPSOs. Mk5 builds on over 40 years of Artemis pedigree, combining proven microwave antenna tracking techniques with Guidance Marine’s new innovative Dashboard and commissioning tool. Applications Artemis is suitable for applications which use fixed and mobile structures such as: • Hydrographic and seismic survey • In and offshore positioning and dredging • Track and ship-follow • Pipe and cable laying • Shuttle tanker loading • Dive support Delivering the future in dynamic positioning with consistently accurate products.

The Artemis System The Artemis system has three main components which vary depending on the system configuration Fixed Station Artemis sensor is installed on the FPSO Mobile Station (position determined) Artemis sensor is installed on a shuttle tanker equipped with a DP system Artemis Dashboard Software is used by the DP Operator to control the Artemis sensor. It runs on a marine computer installed on the vessel’s bridge Artemis Dashboard Artemis Service Interface The Artemis Dashboard is a new user interface that has been logically structured and carefully designed to provide an intuitive...

System Configuration The two identical user configurable stations of the standard system are; North* RELATIVE MOBILE ANTENNA BEARING Relative Mobile Antenna Bearing Mobile Station - installed onboard the vessel of which the position must be determined. Fixed Station - installed at a fixed point, such as an oil MOBILE STATION FIXED STATION Standard System Principle of Operation The system is locked in when the antennas of the fixed and mobile station automatically track each other by maintaining a continuous wave (CW) microwave link. This tracking is such that the imaginary line connecting...
