US-based Lockheed Martin has signed a $28.3m contract with Federal Aviation Administration (FAA) to continue providing technical support to its microprocessor-en route automated radar tracking system (Micro-EARTS).

Micro-EARTS has been designed to receive and integrate air traffic data from multiple surveillance sources, and then display the data for use in air traffic control.

The system is currently implemented in four FAA facilities at Guam, Hawaii Alaska and Puerto Rico, as well as at the FAA Academy and the William J. Hughes Technical Centre.

"We look forward to providing lifecycle support services that ensure Micro-EARTS is a superior automation system for years to come."

Micro-EARTS is an easily adapted application with more than 20 years of operative proficiency for the National Airspace System.

It performs well in large consolidated facilities and also small configurations, as well as helps deliver common air traffic control functionality to all Micro-EARTS sites with standard software and hardware models.

Lockheed Martin Information Systems and Global Solutions Transportation and Financial Solutions vice-president Paul Engola said: "In conjunction with the FAA, Lockheed Martin developed and deployed Micro-EARTS and continues to provide development and maintenance support.
