Sensis Multistatic Dependent Surveillance system to enhance safety and efficiency at Portugal's busiest airport.


EAST SYRACUSE, NY /PRNewswire/ -- NAV Portugal has selected Sensis Corp. Multistatic Dependent Surveillance (MDS) for surface surveillance at Lisbon Airport. The system will enhance safety on the ground and provide accurate surveillance out to five nautical miles from the airport to improve efficiency.

"There are a number of important factors we weighed in making the selection for the Lisbon multilateration project, specifically technical performance, price, delivery schedule and past performance," said Sofia Azevedo, head of communication and image, NAV Portugal. "Sensis' solution offers the strongest combination of these factors, particularly their proven history of deploying multilateration systems for ANSPs around the world and their record of technical performance."

Sensis MDS uses multiple low-maintenance, non-rotating sensors to triangulate aircraft location based on transponder signals and 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, Sensis MDS provides consistent, accurate surveillance. MDS' architecture and advanced multi-path elimination algorithms means the optimal number of ground stations is used reducing cost and complexity. Additionally, each MDS sensor supports Automatic Dependent Surveillance-Broadcast (ADS-B).

"With Sensis MDS, air traffic controllers at Lisbon will have a highly accurate, frequently updated view of the airport surface that will enable them to more efficiently manage traffic on the ground," said Tony Lo Brutto, vice president and general manager of Sensis Air Traffic Systems. "The solution will also provide Lisbon with approach and departure coverage out to five nautical miles from the runways."

Sensis multilateration is the most field-proven system in the industry, with more than 90 sites worldwide. More than 50 airports worldwide rely on Sensis technology as a critical component of a complete Advanced-Surface Movement Guidance and Control (A-SMGCS) solution.
