Lisbon International Airport expands Saab terminal surveillance system

Swedish aerospace technology firm Saab said it has successfully completed the expansion of its surface multilateration system at Lisbon International Airport into a Wide Area Multilateration deployment for Terminal Maneuvering Area surveillance.

According to Saab, Nav Portugal will use the WAM surveillance data to complement existing radar coverage of flights in the Lisbon Vectoring Area, with enhanced coverage of low flying aircraft.

Previously, Saab´s surface multilateration system for Lisbon´s Advanced Surface Movement Guidance and Control System (A-SMGCS) was deployed on-time and accepted into operation.

The WAM system, comprised of existing A-SMGCS sensors and additional sensors in a wide area formation, provides tracking of Mode S, Automatic Dependent Surveillance Broadcast (ADS-B) and Mode A/C targets.

Saab 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.

By employing advanced processing techniques, a Saab multilateration system uses the minimal number of sensors for a less complex, lower lifecycle cost solution. Additionally, each multilateration sensor deployed by Saab supports ADS-B, providing an infrastructure that is ready for current surveillance needs and tomorrow´s avionics.

Almost 100 sites worldwide have chosen Saab multilateration to enhance safety, efficiency, capacity and cost savings through airport surface surveillance, wide area surveillance and airport surface management.

Saab provides the global defense and aviation market with advanced sensor technologies, next-generation radars, automation, modeling and simulation solutions. it serves military, civil aviation, airport and airline customers in more than 40 countries across six continents.
