Table 1:- Turbine Data


To provide additional granularity to the radar analysis and as a basis for discussion with NATS and the MOD, turbine heights of 204m and 220m were also included in the modelling.


19. As the turbine dimensions and layout have not been determined, Cyrrus identified “simulated” turbine locations along the western and northern boundaries of the East Anglia THREE site to illustrate the extent of radar coverage at the different maximum tip heights. These “simulated” turbine locations are shown in the following diagrams as white dots.


16.3.5 Terrain Data


• ASTER GDEM 1.5 arc seconds resolution. • NextMap 25m DTM in area around radars (Perpetual Licence)


16.3.6 Analysis Tools


• ATDI ICS Designer v 3.4.1 x64 R1343 Radio Network analysis tool • Global Mapper v14 • ATDI plugin for Global Mapper V1.00 • AutoCAD 2014 and ZWCAD 2011


20. Ordnance Survey National Grid Reference (OSGB36) is used as a common working datum for all mapping and geodetic references.


21. All heights are Above Mean Sea Level (AMSL). Newlyn datum.


22. Mapping datum transformations are made using Global Mapper (Blue Marble) or OS Grid Inquest (OSTN2).
