Saab Sensis selected for wide area multilateration surveillance in Seoul, Korea

EAST SYRACUSE, N.Y., 8 March 2012. Lotte officials have selected Saab Sensis Corp., a subsidiary of defense and security company Saab, to deploy a wide-area multilateration (WAM) system in Seoul, Korea. The WAM system will be used for surveillance of flights in close proximity of the Lotte World Tower, which is being constructed near Seoul Air Base in Seoul, Korea.

Saab Sensis will provide WAM surveillance of flights within 10 to 15 nautical miles around the tower to Republic of Korea Air Force (ROKAF) air traffic controllers. It marks the first operational deployment of conflict detection and alerting capabilities for a WAM surveillance system, according to a spokesperson.

Saab Sensis will deliver a WAM display along with conflict detection and alerting that will provide ROKAF air traffic controllers with advanced warning of aircraft operating too close to the tower.

Saab Sensis multilateration uses multiple low-maintenance, non-rotating sensors to triangulate aircraft location based on transponder signals, providing air traffic controllers with precise aircraft position and identification information regardless of weather conditions. With a higher update rate and greater positional accuracy than traditional radar, Saab Sensis multilateration delivers effective surveillance for increased safety, capacity and efficiency of airspace and surface operations. Each multilateration sensor deployed by Saab Sensis supports Automatic Dependent Surveillance--Broadcast (ADS-B), providing an infrastructure that is ready for today's surveillance needs and tomorrow's avionics, says a spokesperson.

"Lotte, in conjunction with ROKAF evaluated a number of options to address the challenging surveillance needs around the Lotte World Tower. We determined that Saab Sensis' solution best met the technical performance requirements and deployment timeframe," says Hwanghee Lee, Lotte program director. "In addition, the Saab Sensis system satisfies ROKAF's requirement for an accepted technology in operational use by the U.S. FAA and DOD."

"This unique application further demonstrates the flexibility of WAM technology to effectively address new surveillance demands," says Ken Kaminski, vice president and general manager of Saab Sensis. "Saab Sensis will leverage its extensive experience in airport surface conflict detection and alerting algorithms and apply it to the Lotte World Tower WAM system. This will enable ROKAF controllers to enhance airspace safety through the industry's first deployment of conflict detection and alerting built into a WAM surveillance system."
