The Airports Authority of India (AAI) plans to automate the air traffic control (ATC) systems at Chennai International Airport (MAA).
The AAI has signed an $8.9m (Rs42 crore) agreement with US-based Raytheon, which is currently studying the existing airport procedures.
The automated ATC system will offer improved air safety and a greater ability to handle aircraft movement during peak hours.
The new ATC system is expected to begin operations within a year. The airport also plans to install a new radar system by 2010.
