Saab Sensis Wide Area Multilateration Now Providing Surveillance of Flights Operating Near Korea's Lotte World Tower

Saab Sensis' Wide Area Multilateration (WAM) system is now providing surveillance of flights operating in close proximity of the Lotte World Tower being constructed near Seoul Air Base, Korea, to Republic of Korea Air Force (ROKAF) air traffic controllers.  The system also employs the first operational deployment of conflict detection and alerting capabilities for a WAM surveillance system, further enhancing safety of flights.

The Saab Sensis WAM is enhancing the safety of the tower by providing an extra level of surveillance, tracking all flights within 10 to 15 nautical miles of the tower. The system uses Saab Sensis-developed conflict detection and alerting algorithms to provide ROKAF air traffic controllers with advanced warning of aircraft operating too close to the tower. The surveillance data and conflict alerts are shown on dedicated Saab Sensis WAM displays.

"Saab Sensis was able to design, deploy and commission the entire WAM system within a year of the contract being signed," said D.H.Na, Expert Adviser/System Integration Division, Lotte. "In addition, ROKAF controllers, Lotte staff  and Hanshin Electronics Co., Ltd. received training on the system from Saab Sensis to ensure safe operation of flights in this unique environment."

Saab Sensis multilateration uses multiple low-maintenance, non-rotating sensors to triangulate aircraft location based on transponder signals. This provides 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, multilateration delivers effective surveillance for increased safety, capacity and efficiency of airspace and surface operations.

By employing advanced processing techniques, a Saab Sensis multilateration system uses the minimal number of sensors for a less complex, lower lifecycle cost solution. Additionally, 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.

"Lotte Tower provided us an opportunity to develop and deploy WAM conflict detection and alerting algorithms as part of the system," said Ken Kaminski, senior vice president of Saab Sensis. "Through this advancement, controllers are provided with an additional layer of safety and improved situational awareness, similar to ground controllers who use an A-SMGCS."
