Army train to check detection of GNSS disruption


DIU accelerates business GEOINT and NAVWAR instruments and capabilities to the warfighter

The U.S. Protection Innovation Unit (DIU) shall be testing methods to mitigate disruptions to GNSS alerts this fall.

Disruptions embrace these from intentional sources, equivalent to spoofing, in addition to intentional or unintentional  jamming. Intentional  techniques could be utilized by adversarial nation states, felony networks or privateers.

The shared pursuits between the federal government and personal residents alike for consciousness of GPS disruptions make business options ultimate; data and perception could be broadly shared not simply inside the U.S. Division of Protection (DOD), however throughout businesses, allied companions and the general public as wanted.

Within the Fall of 2021, the DIU launched the Harmonious Rook prototype venture to deal with the necessity for scalable, persistent consciousness of positioning, navigation and timing (PNT) disruptions throughout the globe.

This September, the Harmonious Rook workforce will assist the U.S. Army 1st Armored Division’s Command Publish Train (CPX) on the Nationwide Coaching Heart (NTC), Fort Irwin, California. The train is targeted on large-scale fight operations (LSCO) and supposed to emphasize the division headquarters’ means to deploy to an austere location and command and management its items using an artificial coaching atmosphere.

Parallel to this coaching occasion is the 2nd Brigade, 1st Armored Division’s exterior validation train, additionally at NTC, through which the 2nd Brigade shall be confused and evaluated on its means to deploy whereas contested and conduct LSCO workouts towards a reside opposing power.

A number of DOD and civilian businesses are taking part, together with the Nationwide Air and House Intelligence Heart (NASIC) and the Nationwide House Intelligence Heart (NSIC). A number of non-traditional distributors and non-governmental organizations are additionally supporting Harmonious Rook, from information supply, to machine studying analytics, to visualization and contextualization.

Vendor Participation

A number of Harmonious Rook distributors will take part in notable DoD and worldwide workouts. In August 2022, prototyping firms will assist the Southeast Asia Cooperation and Coaching (SEACAT) train, the place greater than 20 Indo-Pacific nations will practice and collaborate on the widespread purpose of maritime crises and unlawful actions response.

Throughout this multinational train, business companies will present space-based geolocation studies and maritime analytical providers, and combine the insights into the U.S. Navy’s and Division of Transportation’s shared visualization platform, Seavision.


DIU can be working to discover using publicly accessible PNT information to attract perception from home GPS interference occasions.


“Mapping GPS disruptions and contextualizing patterns of conduct are key to mitigating the results of degraded PNT in addition to enabling security of navigation below such circumstances,” mentioned Lt. Col. Nicholas Estep, Harmonious Rook program supervisor, USAF. “As an alternative of growing, constructing, and deploying {hardware} tailor-made for assortment of navigation warfare operations, we’re accessing at present accessible business information and analytics to deal with the necessity for PNT situational consciousness. There are billions of GPS customers and units distributed the world over that could be adversely affected and turning the vulnerability into a bonus for discovery, classification and attribution of such malicious exercise is a key facet of this effort.”

“The Harmonious Rook venture is a really promising new method that enhances conventional assortment methodologies, as it would assist our prospects by sharing evaluation because of the unclassified and business nature of the information,” mentioned Scott Feairheller, senior analyst at NSIC.

“Whereas the Army works diligently to accumulate related tools to help within the real-time recognition and characterization of potential adversary interference, we should leverage non-organic, commercially accessible software program and tools, like Harmonious Rook, as a stopgap to extend consciousness, seize digital key terrain and maximize lethality,” mentioned Lt. Col. Patrick Jones of 1st Armored Division’s House Assist Aspect (SSE). In the course of the train, capabilities shall be examined to assist intelligence, data operations, and command and management parts with business geospatial and navigation warfare consciousness on the tactical stage.

DIU’s Harmonious Rook program will not be restricted to the DoD and the malicious exercise extra generally noticed abroad and in fight environments. DIU can be working to discover using publicly accessible PNT information to attract perception from home GPS interference occasions, a mission with curiosity from the U.S. civil businesses.

With widespread customers and subscribers that depend on PNT providers, any intentional or unintentional disruption can result in extreme transportation, communication and monetary implications. This highlights the significance of bringing each authorities and private-sector industries collectively to establish, attribute and mitigate GPS interference as rapidly as attainable.
