Thales unveils its new multi-mission Primary Surveillance Radar, the TRAC SIGMA with simultaneous capacity for Approach and Long-Range Air surveillance for both civil and military Air Traffic Control.

In an increasingly congested air traffic environment, the new TRAC SIGMA L-Band radar is the only radar of its class to discriminate small aircraft at an extended range (300KM), helping ensure the 3NM distance separation over the entire airspace and not just for final approach.

Inheriting technology from the TRAC family, the TRAC SIGMA offers higher availability, resistance to jamming and radar interferences, extended coverage, improved discrimination and accuracy, as well as full 3D air picture ensuring smoother coordination between Civil and Military missions.

TRAC SIGMA Julien Lutt / CAPA Pictures With more than 1,200 Air Traffic Control radars installed in over 100 countries, Thales is a leader in this market and today unveils TRAC SIGMA, its new Primary Surveillance Radar, helping to ensure faster coordination between military and civil operations in an ever-congested airspace.

With the increasing congestion of airspace due to the growing number of aircraft, military aircraft will need to fly at lower and higher altitudes, and the minimum distance between aircraft will become ever more crucial. In line with ICAO recommendations, it will become essential for both civil and military air traffic controllers to optimize the minimum horizontal separation between aircraft to three Nautical Miles (NM) across the entire airspace - not just during final approach.

The TRAC SIGMA, the latest product from Thales's worldwide field proven TRAC Primary Surveillance Radar family, leverages the latest in digital technologies; bringing to the market outstanding performances with enhanced detection capabilities at an extended coverage. It is the only radar of its class to discriminate small targets with precision at an extended range (300KM), helping ensure the 3NM distance separation over the entire airspace, while also ensuring approach surveillance.

This radar inherits advanced 3D detection capabilities and unmatched discrimination of small aircraft wherever they are flying whether at high altitude, low altitude or long distance, a high availability/reliability due to full redundancy and hot swap component replacement, jamming/interference resistance, as well as compliance with international standards and regulations. The 2 in 1 radar also helps improve life-cycle costs with optimized infrastructure and resources.

Eric HUBER, Vice President Surface Radars, Thales, said, With over 50 years' experience in this field, Thales is continuously investing to lead the latest innovations in the Air Traffic Control radar market, helping ensure safer skies. TRAC SIGMA offers a single sensor for simultaneous approach and long-range surveillance supporting all air traffic control missions, and enables ATCOs to meet the challenges related to optimizing an increasingly congested airspace.
