JAJ2-16 Anti-Interference Module for Drone Defense - 16 Channel Anti-Jam Protection
The JAJ2-16 is a sixteen-channel navigation anti-interference module built for drones that must keep flying inside a contested electromagnetic environment. Sixteen channels give the module the degrees of freedom to null up to 15 separate interference sources simultaneously, which is what separates it from small two- and four-channel units that lose effectiveness as soon as more than one emitter is present.
Why Channel Count Matters
An adaptive antenna array cancels interference by steering a null toward each source. The number of independent nulls it can place is limited by the number of elements, so a four-element array handles up to three emitters and a sixteen-element array handles up to fifteen. Modern counter-UAS deployments rarely use a single jammer; airports, military sites and border zones typically operate several emitters covering different sectors and bands. The JAJ2-16 is dimensioned for that reality.
Protection Against 15 Interference Sources
The module continuously measures the direction of arrival for every signal reaching the array and separates satellite signals, which come from high elevation angles across the sky, from interference, which almost always originates at or near ground level. Nulls are placed on the interference directions while gain toward the satellites is preserved, so the receiver keeps a valid position solution rather than dropping lock. Protection applies to both broadband jamming and coherent spoofing.
Construction
The unit weighs 2kg and is built from metal and engineering plastic, with the metal structure providing both the ground plane the array requires and the shielding that keeps the receiver front end clean. It is designed as an installable module rather than a laboratory instrument, so it goes onto medium and large UAV platforms, vehicles and fixed masts where navigation continuity is a mission requirement.
Key Features
- 16 independent channels for maximum interference rejection
- Simultaneous protection against up to 15 interference sources
- Direction-of-arrival based nulling, effective against jamming and spoofing
- Keeps satellite navigation data undisturbed under attack
- Metal and engineering plastic construction, 2kg
- Integrated ground plane and receiver front-end shielding
- Designed for medium and large UAV platforms
- Also suitable for vehicle and fixed-mast installation
- Maintains position lock instead of failing over to inertial hold
- Modular installation, transferable between platforms
- Scales down to 4-channel variant where fewer emitters are expected
- Suitable for drone defense and GNSS resilience programmes

Selection Guidance
Choose channel count based on how many simultaneous emitters the operating area is expected to contain. Where a single jammer is the realistic threat, the 4-channel JAJ2-4P is lighter and cheaper. Where several emitters cover different sectors, as at airports, border posts and defended military sites, the 16-channel version is the correct choice because a four-element array runs out of nulls long before the threat does.
