CASA Certifies Deployment Of Integrated Maneuvering And
Approach Surveillance System Along With Ground Monitoring
The Civil Aviation Safety Authority of Australia has granted
operational certification to Saab Sensis Corporation for deployment
of its Wide Area Multilateration (WAM) and Precision Runway
Monitoring (PRM) at Sydney Airport, Australia. The WAM system is
now providing Airservices Australia air traffic controllers with
terminal airspace surveillance for improved coverage and separation
services within the airport's Terminal Maneuvering Area (TMA) and
precision approach surveillance for separation of flights on
independent parallel approaches to Sydney's closely spaced parallel
runways for increased efficiency. The Sydney WAM system is now the
first single WAM system in the industry to simultaneously perform
both complex surveillance tasks.
The increase in air traffic at Sydney and the development of the
nearby Botany Bay port facility led Airservices to select Saab
Sensis to deploy a single WAM system to provide low level terminal
airspace surveillance (out to 40 nm) for 3 nm separation services
in the TMA and PRM for independent parallel approaches in
Instrument Meteorological Conditions.
The sensors used for WAM and PRM are the same as the existing
Saab Sensis sensors currently deployed for Sydney's Advanced
– Surface Movement Guidance and Control System (A-SMGCS) for
simplified maintenance and training.
"The single Saab Sensis WAM system is enabling Airservices to
achieve two critical goals at once: improve terminal area
surveillance and replacement of legacy PRM radar," said Airservices
Acting General Manager Technology and Asset Services, Dan
Galazowski. "We now have a terminal area surveillance solution that
further enhances safety and provides the surveillance needed for
precision approaches."
Multilateration uses multiple low-maintenance, non-rotating
sensors to determine 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
generates effective surveillance for increased safety, capacity and
efficiency of airspace. By employing advanced processing
techniques, a Saab Sensis multilateration system uses the minimal
number of sensors for a less complex solution. Additionally, each
multilateration sensor deployed by Saab Sensis supports Automatic
Dependent Surveillance – Broadcast (ADS-B), providing an
infrastructure the company says is ready for current surveillance
needs and future avionics.
"The Saab Sensis system at Sydney is the industry's first
dual-use WAM system where a single system is responsible for two
complex, disparate surveillance requirements, further demonstrating
Saab Sensis' ability to meet the most stringent surveillance
demands of safety regulators," said Ken Kaminski, vice president
and general manager of Saab Sensis. "With Saab Sensis WAM,
Airservices Australia has a flexible, extensible solution that is
compatible with today's and tomorrow's avionics and can readily
grow with the airport."
