Initial Integration
Testing

Northrop Grumman Corporation and the U.S. Marine Corps successfully completed an Initial Integration Event (IIE) in November 2016 for the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) system.

«The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability»,” said Roshan Roeder, vice president, mission solutions, Northrop Grumman

The three-week IIE demonstrated G/ATOR’s Ground Weapon Locating Radar (GWLR) mode’s ability to detect and track multiple types of Rocket, Artillery and Mortar (RAM) rounds simultaneously. Over 40 different weapon scenarios were evaluated through the live fire event, and more than 700 live shots were fired, including a variety of RAM rounds. GWLR successfully tracked projectiles including volley fire between 3.7 miles/6 km and 31 miles/50 km, demonstrating G/ATOR’s long range capability. Volley fire capability is the ability to detect and track multiple RAM projectiles intentionally fired in very rapid sequence in an attempt to overwhelm radar capabilities.

«GWLR mode detects and tracks time-critical incoming threats, calculates an approximate impact point, and then tracks the threat’s trajectory back in time to estimate a firing position, allowing counterfire forces to engage rapidly», said Roshan Roeder, vice president, mission solutions, Northrop Grumman. «The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability».

The AN/TPS-80 G/ATOR system is multi-mission, performing four principal missions using the same hardware: short-range air defense, tactical air operations control, counterfire target acquisition (GWLR mode) and future air traffic control. GWLR mode adds software to the G/ATOR system to detect, track and identify RAM projectiles, both 360-degree and sector-only. The GWLR mode addresses multiple types of simultaneous threats. Adding this capability will allow G/ATOR to replace five legacy United States Marine Corps (USMC) radars.

G/ATOR Block II

Northrop Grumman Corporation and the U.S. Marine Corps have achieved two major milestones in developing the Ground Weapon Locating Radar (GWLR) mode for the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR).

The GWLR preliminary design review in February and critical design review in August marked the successful completion of the design reviews for the development of this capability. These reviews will be followed by an Initial Integration Event (IIE) in October to perform initial testing of the system and take data on several targets to assist in the remaining integration work.

The IIE will be an initial demonstration of G/ATOR’s ability to detect and track multiple types of rocket, artillery and mortar rounds simultaneously. G/ATOR has a significant output power advantage compared to current U.S. counter-fire target acquisition radars, equating directly to longer-range threat detection and tracking. This provides additional time to successfully engage and negate these threats with both current and future longer-range engagement weapons.

«It is critical that we deliver this capability to our warfighters on time and at an affordable cost», said Roshan Roeder, director, mission solutions, Northrop Grumman. «Our unmatched experience in developing and fielding algorithms for the counter-fire targeting mission, combined with internally-funded risk reduction systems that have participated in nearly 1,000 live fire events prior to this contract award, ensured the successful completion of these reviews and support an initial operating capability for G/ATOR Block II in mid-2018».

The GWLR mode adds software to the G/ATOR system to detect, track, and identify rocket, artillery, and mortar projectiles, both 360-degree and sector-only. The GWLR mode addresses multiple types of simultaneous threats.

In addition to providing a broad range of optimized radar capabilities, AN/TPS-80 G/ATOR provides automatic adaptability via a scalable open system architecture
