A $4.7m satellite-based air traffic system has been unveiled in the US state of Colorado.
The first-of-its-kind system was built by Sensis Corporation, at the behest of the state of Colorado as part of a modernisation effort to curb delays at its airports.
The new monitoring system uses 20 sensors clustered around four airports within the Rockies to monitor radio broadcasts from planes to determine a plane’s location.
The state of Colorado and Federal Aviation Administration (FAA) have plans to expand the coverage to six other airports in the region.
The non-radar system is similar to the satellite-based system that the FAA plans to install across US airports in the next decade to replace the current radar system.
The US Government plans to replace radar with the satellite-based tracking system by 2020.
