NATS Selects Sensis Multilateration for Surface Surveillance at London
Stansted Airport

Third Major UK Airport to Increase Safety and Efficiency with Sensis MDS

EAST SYRACUSE, N.Y., March 30 /PRNewswire/ -- NATS (formerly National Air
Traffic Services), the UK's major air navigation service provider, has
selected Sensis Multistatic Dependent Surveillance (MDS) for ground
surveillance at London Stansted Airport. Sensis MDS will provide full
coverage of the airport's runway, taxiway and stand areas to enhance the safe
and efficient movement of aircraft on the ground. NATS has selected Sensis
MDS for ground surveillance as a result of its successful performance at
London Heathrow and Gatwick airports.

"The selection of Sensis MDS for Stansted was based on the many benefits we're
experiencing at Heathrow and Gatwick with the same technology," said Alistair
Clark, NATS Program Manager. "Stansted is a single-runway airport that
requires the runway to be in operation in all weather conditions. MDS helps
achieve this goal by providing accurate surveillance no matter the weather."

Sensis MDS uses multiple low-maintenance, non-rotating sensors to triangulate
aircraft location based on transponder signals and provide 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. Due to advanced processing techniques, an MDS system
uses the minimal number of sensors for a less complex, lower lifecycle cost
solution. Additionally, every MDS sensor deployed by Sensis also supports
Automatic Dependent Surveillance - Broadcast (ADS-B).

"Sensis MDS architecture has the flexibility to easily accommodate future
growth," said Tony Lo Brutto, vice president and general manager of Sensis Air
Traffic Systems. "Each ground station can also efficiently transition to, and
serve as a back-up system to ADS-B with no equipment modifications."

Sensis multilateration is the most field-proven system in the industry, with
approximately 100 sites worldwide using the technology.
