Finnish air navigation service provider and airport operator, Finavia has ordered 39 Quadrant ADS-B sensors and 12 transmitters from COMSOFT to implement its Wide Area Multilateration (WAM) network covering about a quarter of the country.
Quadrant ADS-B sensors have a range of above 300nm and can be used multilaterally to provide longer range radar with higher accuracy at a lower cost.
The sensors will perform complex surveillance tasks in areas lacking all-encompassing coverage.
Finvavia's project also includes the deployment of an ARTAS tracker as main surveillance data processing system at Helsinki-Vantaa airport.
This turnkey solution will deliver an advanced estimate of the air situation and combines conventional radar data, Mode S elementary and improved surveillance data, automatic dependent surveillance (ADS) data and Wide Area Multilateration (WAM) data into one coherent picture.
ARTAS tracker will further facilitate Finavia to make complete use of its surveillance capabilities currently being enhanced, while the simultaneous execution of both projects allows for a complete and smooth integration of the new surveillance data sources into the ARTAS configuration.
The order also includes the delivery of the COMSOFT Radar Monitoring Display (RMD) as independent surveillance display, and the universal monitoring system Enhanced Supervision Management System (ESMS).
The project will be completed by the end of the year.
The country is also planning to launch three additional WAM system installations in central, Northern and Eastern Finland for expansion of coverage.
