The company the U.S. Federal Aviation Administration chose in August 2007 to install the ground infrastructure needed to track aircraft by automatic dependent surveillance-broadcast (ADS-B) plans to complete that network in the continental U.S. this month. McLean, Va.-based Exelis, which was called ITT when the FAA awarded it the ADS-B contract, said 658 of the 660 planned ADS-B ground radio stations will enter service this year, including all 601 the company is installing in the lower 48 states.
