Glasgow Prestwick Airport (GPA) Ltd is seeking to procure a Wind Farm Radar Mitigation System that includes the following lots:

— Lot 1 — A Surveillance Air Traffic Services (ATS) Primary Surveillance Radar (PSR) capable of mitigating the effects of wind turbines within the GPA Operational Volume, providing 360° of coverage and to a range of no less than 20 nm;

— Lot 2 — A Surveillance ATS PSR capable of mitigating the effects of wind turbines within the GPA Operational Volume, providing 360° of coverage and to a range of no less than 20 nm that can be developed to provide wind farm tolerance to no less than 40 nm by 2017;

— Lot 3 — A Multi Radar Tracker (MRT), to integrate/Fuse all GPA surveillance Data Sources for display to the Air Traffic Controller (ATC), that includes:

— Lot 1 and/or Lot 2 mitigated Surveillance Data;

— The existing S511 PSR Plot Extracted (PEX) Radar Data and/or Analogue Radar Video;
