Electronic Protection of Infrastructure (EPI)
A Powerful Defense Against Precision
Drone and Missile Attacks
Drones and missiles wars in 2026
It’s not prophecy or fiction; it has already happened!
Houthi rebels attacked Saudi oil infrastructure using Iranian drones in 2019.
ARAMCO damages are estimated of more than 5 billion US dollars from Houthi rebels attacked Saudi in 2019
Azerbaijan
Armenia war in 2020 won by Israeli drones taking down entire radar network and anti-air infrastructure
Russia stumbles against Ukraine's anti-tank weapons
Russia Ukraine war has reverted to drones and missiles war
Russia stumbles against Ukraine's anti air weapons
Russia Ukraine war has reverted to drones and missiles war
Israel defeats Iran
Hezbollah and Hamas thru air superiority and precise fire coordinated by attack and reconnaissance drones
Iranian Shahed 136 manages to hit with precision thanks to
GPS navigation and 4 elements Anti Jam CRPA antenna
Russia buys Iranian Kamikaze drone - Shahed 136,
and later builds its own version in Russia – Geran 2
Russia widens usage of drones to hundreds per single attack
Russia widens usage of drones to hundreds per single attack, targeting energy and other Ukrainian infrastructures
Iron Dome cannot down low flying drones
Hezbollah drones penetrate Israel's air defense and hits accurately many military targets and even Netanyahu's bedroom window
Recent numbers of precise guided munition used by Russia
Ukraine and Israel run out of anti-air missiles and ammunition
against drones and missiles
Ukraine loses most of its energy infrastructures to
drones and missiles attacks.
Israel loses its oil refinery and a main hospital to
precise missile hits by Iran
Lesson learned
Drones and missiles attacks are
way cheaper than defending them by hard kill methods.
Conclusion:
Without effective mitigating jamming of GPS, wars will be won by attackers with infinite quantity long-range low-cost GPS guided drones and missiles.
Electronic Protection of Infrastructure (EPI)
This is a solution of Last Line of Defense for any infrastructure against the above-mentioned threats, working independently or part of an anti-aircraft and/or an anti-missile defense system.
EPI - A Powerful Defense Against Precision Drone and Missile Attacks
The EPI system, patent pending, is a grid/grouped array of GNSS jammer units dispersed around critical civilian and military infrastructure, that creates a "minefield", with the purpose of preventing precise hit by long range GNSS guided munition.
The EPI system mitigates the threat's navigation accuracy in the last flight segment to its target (the infrastructure), as long as possible, by jamming GNSS signals all the way to the target and turning the threats from precise to statistic weapon, with the accuracy of the hit dropping from a few meters to many tens or hundreds of meters from the target.
These guided munitions include Smart bombs, Rockets, Ballistic missiles, Cruise Missiles and Armed UAVs, including mixtures and swarms of them, with warheads of tens and hundreds of kilograms of TNT and their ability to accurately strike critical infrastructures, such as energy facilities (electricity, gas/oil), seaports, airports, military installations, government buildings, etc.
Note: GNSS jamming equipment are included in the Wassenaar Munitions list as item ML 11. b: "Satellite navigation system jamming equipment and specially designed components". Therefore, as such its export is regulated by the exporting country, requiring a defense equipment export license.

About Us
Grid-Jam was founded in 2019 following the Iranian drone attacks on Saudi oil facilities.
Those attacks demonstrated that modern drones and missiles rely on precise GNSS guidance to strike critical infrastructure with high accuracy.
Grid-Jam was created by veterans in Electronic Warfare with a clear objective: to deny this precision by disrupting GNSS navigation over protected areas.
By deploying a coordinated grid of GNSS jammers around strategic assets, guided munitions are forced to fly without accurate navigation during their final approach, significantly reducing their ability to hit critical targets.
The nature of these threats and their operational impact are detailed in the Threats section.
Since 2022, the large-scale use of GNSS-guided drones and missiles in Ukraine has confirmed that these threats are now a dominant form of warfare, as demonstrated in the Case Studies section.
Grid-Jam systems were evaluated and approved as effective against GNSS-guided drones, including the Shahed-136 platform.
The EPI concept, system architecture, and operational principles are described in the What is EPI and How It Works sections.
As drone and missile production continues to increase and air-defense resources become constrained, protecting critical infrastructure requires additional defensive layers.
Grid-Jam provides scalable GNSS denial solutions, ranging from local site protection to regional and national deployments. Deployment models are outlined in the Implementation section, and available systems are detailed in the Products section.
Common operational and strategic questions are addressed in the FAQ.
Grid-Jam provides a practical, defense-oriented solution to reduce the impact of modern precision attacks on critical infrastructure.
