JERUSALEM — As warfare becomes increasingly saturated with electronic threats, one Israeli defense firm is stepping up to address a growing vulnerability the disruption of satellite navigation systems that modern militaries rely on for everything from drones to precision-guided munitions.
InfiniDome, an Israeli technology startup, says its anti-jamming solutions are designed to restore reliability to GPS systems, especially on smaller platforms that often lack the space and power to carry traditional protection systems.
“You can get a small, handheld jammer on a random Chinese website that can kill GPS signals for hundreds of meters or take down UAVs from kilometers away,” said Omer Sharar, cofounder and CEO of infiniDome, in a recent interview with Breaking Defense. “It is like in cyber, with a denial-of-service attack. When you flick the switch on, nothing has a GNSS signal.”
The Invisible Battlefield: Jamming and Spoofing

Beyond the blunt tool of jamming, militaries are increasingly facing the threat of spoofing, the injection of false GPS signals into a system to mislead it. Since October 2023, following Israel’s military operations in response to the Hamas attacks, spoofing incidents have spilled into civilian life. Many Israelis reported their GPS devices inaccurately placing them in far-off cities like Cairo, Amman, or Beirut.
Sharar explained that GNSS signals are incredibly weak by the time they reach the Earth’s surface. “They are as weak as a 20-watt lightbulb in California trying to be picked up in New York,” he said, making them easy to disrupt with minimal tools.
Interestingly, much of the jamming experienced during Israeli military operations wasn’t coming from the adversary, but from the IDF’s systems. “The biggest problem we had in Israel was not ‘red’ jamming from the enemy, but ‘blue’ from the IDF,” Sharar noted.
A Growing Need for Lightweight Protection
While large drones and aircraft can carry extensive anti-jamming systems, the modern battlefield increasingly depends on smaller platforms such as quadcopters and FPV drones, tools that often cannot accommodate bulky hardware.
This is where infiniDome aims to fill the gap. Using a technology known as “null steering,” traditionally employed on large-scale platforms like fighter jets or warships, infiniDome is miniaturizing the technology for small drones and even artillery shells.
“We are building a module that sits like a filter between the receiver and antennas,” Sharar said. “We don’t need special antennas or receivers. You disconnect your GPS antenna and plug it into our box.” This creates a modified signal reception pattern that can deflect interference, he explained.
The company is now exploring the possibility of integrating its tech into 155mm artillery shells, like the U.S.-made Excalibur, whose GPS-guided accuracy has reportedly dropped significantly on the jamming-heavy battlefields of Ukraine, from around 90 percent down to just five to ten percent.
A Global Wake-Up Call
GNSS denial and spoofing are fast becoming global concerns, Sharar warned. InfiniDome has already conducted successful trials with the Indian military and is attracting strong interest from both eastern and northern Europe. “Everyone is waking up,” he said. “It became a reality. It became a painful reality.”
As militaries worldwide reckon with the vulnerability of satellite navigation systems, infiniDome’s approach offers a flexible and scalable countermeasure. From the skies over Gaza to the front lines in Eastern Europe, the company’s vision is clear to “make smart munitions smart again.”
