Airports Authority of India equip new sites with Next Generation Systems

COMSOFT have been commissioned to install a further 14 Quadrant Sensor ADS-B ground stations for Airports Authority of India (AAI), following a successful phase I project roll out.

The follow-up contract, awarded to the German surveillance expert by AAI, will provide additional sites across India with dual-redundant Quadrant Sensor systems able to provide long-range surveillance solutions.

Automatic dependent surveillance-broadcast (ADS-B) has been labelled the Next Generation Airport System, or NextGen, and will ultimately be replacing radar as the main surveillance technique for controlling aircraft worldwide.

The long-range ADS-B technology builds a complete air situation picture from airport surface to beyond 250 Nautical Miles, and is an ideal surveillance solution for a country like India where very long distances have to be covered and regions with extremely high altitudes present a special challenge.

Fourteen National and International airports across India, the Arabian Sea and the Bay of Bengal are already using the accurate and forward thinking air surveillance technology, following the completion of site acceptance testing in October 2012.

COMSOFT’s dual-redundant Quadrant Sensors enhance the accurate and safe surveillance broadcast in all fundamental directions of the South-Asian country to an automated ATM system. Quadrant is the centerpiece of COMSOFT’s air surveillance product family, receiving and processing 1090MHz messages for either ADS-B or multilateration use, in accordance with latest international ADS-B standards.

The worldwide transportation community has clearly recognised ADS-B and multilateration as the surveillance technologies with the greatest potential, given the reliability and ease of installation, combined with high performance at low operation and investment costs.
