Northrop Grumman Corporation has announced that its U.K.-based air traffic management systems subsidiary Park Air Systems has won a contract with Airports Authority of India (AAI) to deliver ground-to-air communications across the country utilising the latest Voice over Internet Protocol (VoIP) communications technology. 

Under the contract, Northrop Grumman Park Air Systems will supply more than 500 pairs of air traffic control (ATC) transmitters and receivers that will be integrated into the AAI IP network. The system will comprise the Park Air T6 transmitter and receiver radios, the Park Air S4 remote control units, filters, multicouplers and antennas. The supplied equipment will be interconnected using the internationally agreed VoIP protocol ED-137.
