The TAMR program is upgrading air traffic control systems at terminal radar approach control (TRACON) facilities across the national air space (NAS) with the Standard Terminal Automation Replacement System (STARS) platform.

What is Terminal Automation?

Terminal automation systems receive surveillance data and aircraft flight plan information. Controllers at radar control facilities use these systems to manage air traffic immediately around major airports, and technicians maintain these systems at facilities.

These systems enable controllers to provide several air traffic control services that are critical to the safety of the national airspace:

  • Separating and sequencing of aircraft
  • Conflict and terrain avoidance alerts
  • Weather advisories
  • Radar vectoring for departing and arriving traffic.

What is TAMR?

The FAA's Terminal Automation Modernization and Replacement program is modernizing the air traffic control systems at TRACON facilities and control towers at the nation's major airports.

TAMR will combine and upgrade air traffic control technologies to the Standard Terminal Automation Replacement System (STARS).

What is STARS?

STARS is a single, state-of-the-art platform that will be installed at TRACONS and control towers. It will:

  • Maintain safety while increasing cost-effectiveness at terminal facilities across the NAS
  • Provide advanced functionalities for controllers, such as state-of-the-art flat-panel LED display and the ability to save controller workstation preferences
  • Offer an easier-to-maintain infrastructure for technicians

TAMR and NextGen

TAMR will ensure that NextGen technologies can operate in the NAS.

Similar to En Route Automation Modernization (ERAM) at air route traffic control centers, TAMR allows TRACON facilities to use Automatic Dependent Surveillance - Broadcast (ADS-B) data.

The phased STARS implementation process began in the early 2000s. The implementation process is expected to be completed by 2020, and will eventually be used by thousands of controllers and technicians.
