G/ATOR

Northrop Grumman Corporation’s AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) multifunction sensor successfully detected and tracked multiple cruise missile threats simultaneously during a recent live-fire test at White Sands Missile Range, New Mexico. G/ATOR successfully tracked each target immediately after launch and passed relevant information in real time to intercept numerous cruise missile targets from multiple angles.

The tests were part of the U.S. Marine Corps’ mid-tier acquisition rapid prototyping effort, known as the Ground Based Air Defense Medium-Range Intercept Capability (GBAD MRIC), a developmental program established to protect high-value areas and assets from airborne threats such as cruise missiles and aircraft.

«During this test event, the AN/TPS-80 demonstrated a combination of performance capabilities during a realistic representation of an adversary attack», said Michael Hahn, director, advanced land radar solutions, Northrop Grumman. «G/ATOR is an expeditionary radar and is unrivaled in its ability to simultaneously provide weapons quality tracks on numerous, concurrent airborne targets while maintaining 360-degree surveillance coverage. The software-defined nature of the AN/TPS-80 was critical in rapidly developing and demonstrating this advanced capability in support of challenging threat scenarios to support the Marine Corps».

The rapid emplacement and displacement of the AN/TPS-80 means troops can quickly stand up this mission capability in the field, perform the mission, and rapidly move assets to avoid vulnerability of enemy targeting. Unlike traditional sensors, multifunction systems like G/ATOR consolidate multiple capabilities into a single sensor, decreasing the size, weight and power requirements. G/ATOR is one piece of the solution providing the joint forces with an operational picture and deep breadth of data to operate in today’s contested environment, in support of the Marine Corps’ Force Design 2030 strategy.

The GBAD MRIC program, led by the USMC, integrates existing systems – specifically, G/ATOR and the Common Aviation Command and Control System (CAC2S) – with components of the Israeli Iron Dome System including the Tamir interceptor to provide integrated surveillance and coverage.

Initial production

Northrop Grumman Corporation has delivered the first AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) that incorporates advanced high power and high efficiency Gallium Nitride (GaN) antenna technology, further improving the system’s operational capabilities. This system was delivered ahead of schedule and is the seventh G/ATOR system delivered in the Low Rate Initial Production (LRIP) phase of the program.

GaN technology provides cost savings and multiple performance benefits including enhanced system sensitivity and increased reliability. All subsequent G/ATOR LRIP and full rate production systems will now incorporate this advanced GaN technology.

Delivery of the first GaN G/ATOR system follows the delivery of six LRIP systems to the Marines that began in early 2017. Utilizing two of those six systems, the Marine Corps achieved G/ATOR Initial Operational Capability (IOC) of the air surveillance mission in February of this year. The remaining four systems will establish IOC for the counter-battery mission later this year. As a result, G/ATOR systems, trained Marines and associated logistics support are now in operational service with Marines.

«The Marine Corps are the first to take delivery of a production ground based multi mission AESA radar that incorporates this advanced GaN technology», said Roshan Roeder, vice president, land & avionics Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) division, Northrop Grumman. «The incorporation of this advanced technology in production radars is unique to the Marine Corps and enables G/ATOR to provide additional mission capability to the warfighter at an affordable cost».

Both the Marine Corps and Northrop Grumman continue to make detailed preparations to successfully execute the full rate production program, which is scheduled to begin in early 2019.

Additionally, given the AN/TPS-80’s open architecture design, Northrop Grumman was awarded a contract through the Office of Secretary of Defense Strategic Capabilities Office in 2016 to support the addition of a fire control mission.

The AN/TPS-80 G/ATOR is an advanced Active Electronically Scanned Array (AESA) multi-mission radar that provides comprehensive real time, 360-degree situational awareness against a broad array of threats including fixed wing aircraft, helicopters, cruise missiles, Unmanned Autonomous Systems (UAS), and rockets, artillery and mortar. It is rapidly deployable worldwide to meet United State Marine Corps (USMC) needs and includes the latest cyber and digital beam forming technology that enables the radar to perform multi-mission tasks at significantly lower operation and maintenance costs compared to existing USMC radar systems.

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.

Northrop Grumman is a leading global security company providing innovative systems, products and solutions in autonomous systems, cyber, Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR), strike, and logistics and modernization to customers worldwide.

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
