This is an assessment of the impact on these not on the navigational safety. The project includes VHF radio communications, VHF direction finding, GPS, AIS, mobile phone networks and Racon positioning system.

Where parameters are variable worst case assumptions have been made to find the bounds of the impacts expected from the wind farm. Previous work has been carried out on the North Hoyle offshore wind farm development. This has involved theoretical studies and then measurements on the completed wind farm. The results from these studies have been summarised in this report and where possible, these results have been used to inform the calculations carried out for the Gwynt y Môr offshore wind farm. A summary of the assessment findings for all the systems bar ship radar is contained in the following table. The systems considered include a variety of radio communication and navigation systems, a number of nearby fixed site marine radar systems, microwave links operated by BHP Billiton, helicopter radar and television broadcast signalsv npower renewables Ltd GIS Specialist +44(0) 1793 877 777 carla.houghton@npower-renewables.com pointOfContact EPSG Geodetic Parameter Registry 2022-11-29 revision WGS 84
