Sydney Airport to Use Sensis Wide Area Multilateration
Airservices Australia has selected Sensis Corporation's WAM (wide area
multilateration) for terminal airspace surveillance and precision approach
monitoring at Sydney.
Sensis' WAM uses multiple sensors, leveraging the company's
MDS (multilateration surveillance technology), to triangulate aircraft
positions based on their transponder signals. It can provide 360 degree
surveillance out to 60 nautical miles from the airport, with a one-second update
rate, which is good enough to monitor parallel runway approach paths, Sensis
says, so it also will replace the existing E-scan precision runway monitor.
Conventional radar coverage has suffered from obstructions from commercial
development around the airport and the adjacent Port Botany container terminal,
which WAM is expected to resolve as well.
Airservices is deploying Sensis products for multiple air traffic surveillance applications throughout
Australia. Sensis WAM will provide air traffic surveillance across Tasmania
while Sensis
A-SMGCS (advanced - surface movement guidance and control systems) is being
deployed at the airports of Brisbane, Melbourne and Sydney. 10-31-2007. |
