Air Traffic Control - Secondary Surveillance

Easat’s high-gain open planar SSR/IFF array meets the worldwide LVA antenna requirements and is offered as a stand-alone version (shown below) or co-mounted onto Easat’s EA5325 or EA5025 Primary Surveillance antennas, as illustrated opposite. Available in either Standard (single beam) or Monopulse configurations, the antenna offers a shaped elevation pattern, a sharp horizon rolloff and superior gain, providing excellent system performance and reduced ground illumination. This antenna is Mode S compatible (Level 2).

The antenna is operational worldwide.

Mechanically, the unit offers an open-antenna structure for low wind loadings, encapsulated dipole columns for superior weather protection, and a turning unit capable of operations in severe environments with temperatures as low as -50º C.

For the stand alone version the EP0409 turning unit is available in single or dual drive configurations, with highly accurate single or dual azimuth encoders or Inductosyn®. For the co-mounted version EP1643 is used, which shares the same features. The azimuth accuracy offered by this system meets or exceeds all current worldwide recommendations for redundancy and azimuth accuracy from this type of equipment.
