Maldives Airport has awarded a contract to Comsoft for the deployment of its Quadrant Sensor ADS-B ground systems on the archipelago island chain.
As part of the contract, ADS-B sensors will be deployed to offer enhanced air surveillance on the northern and southern Maldives, while two additional Quadrant sensors have already been installed at the Ibrahim Nasir International Airport in Malé.
The deployment at the airport included intensive on and offsite training, and was completed within three months; the ADS-B technology has commenced transmission of surveillance data to ATC client systems.
The Quadrant Sensor System, which is compatible with the international ASTERIX standard and EUROCAE ED-129/149, is intended to provide surveillance obtained from ADS-B reports of international aircraft, in addition to the data derived from the large number of seaplanes taxiing in the vicinity of Malé airport.
The sensor is capable of forming a multilateration network and allows the requesting of specific information, while its sectorised interrogation module with eight directional antennas enables target-oriented interrogations in any freely selected direction.
Features of the ADS-B ground station include a control and monitoring system (QCMS) that allows the remote setting of all system parameters and ensures permanent performance supervision during operation.
The Quadrant system, integrated with interrogators and ADS-B sensors, will replace Mode S radar.
In November 2012, the Maldives terminated a $511m contract awarded to Indian infrastructure firm GMR Group for the modernisation and management of Malé airport, but the termination was stayed by the High Court of Singapore the following month.
