The big white golf ball

You may know what the big white golf ball is if you live bear CFB Greenwood, but if you’re just traveling around the Annapolis Valley this large white object on Stronach Mountain might be a bit of a curiosity.

Area Surveillance Radar/Secondary Surveillance Radar (ASR/SSR)

While it looks like a huge golf ball, it’s actually a structure enclosing a radar antenna used to provide Air Traffic Management (ATM) services for the Military Terminal Control (MTC) centre at 14 Wing Greenwood.

The radar antenna is on a lattice steel tower approximately 20 to 30 m in height and supported on a concrete slab, measuring approximately 10 m x 10 m in size. The Radome (structure enclosing the radar antenna) is approximately 12 m in diameter situated on the lattice steel tower.

The Airbus Defence and Space supplied ASR-NG radar (Airport Surveillance Radar Next Generation) is  used for approach control at the airfield itself and for airspace surveillance within a radius of 64 NM (110 km) to safely coordinate, amongst other things, military flight movements with civil air traffic.

The ASR-NG is combined with the MSSR 2000I (MSSR = Monopulse Secondary Surveillance Radar) secondary radar for automatic identification of individual aircraft. It meets the new air traffic control standards “Mode 5”, “Mode S” and “ADS-B”.

The Royal Canadian Air Force (RCAF) installed the seventh and final radar system associated with the Area Surveillance Radar/Secondary Surveillance Radar (ASR/SSR) project at 14 Wing Greenwood, Nova Scotia.

Announced in 2013, the project was mandated to replace the aging Terminal Radar and Control Systems (TRACS) with six new air traffic control systems and one training system. The old radar equipment was replaced at six sites: 3 Wing Bagotville, Quebec; 4 Wing Cold Lake, Alberta; 5 Wing Goose Bay, Newfoundland and Labrador; 8 Wing Trenton, Ontario; 14 Wing Greenwood, Nova Scotia; and 19 Wing Comox, British Columbia.

One additional radar system was delivered as a technical training suite (Aerospace Telecommunication Engineering Support Squadron – Trenton, Ontario.
