[Exclusive] Hanwha Aerospace Moves Toward Deployment of Drone Anti-Jamming Technology

Preparing for Anti-Jamming Navigation Solution Business
Trademark Application Filed as "LAGNAS"
Key Countermeasure Against Drone Neutralization
"Completed Military-Led Performance Tests"

Hanwha Aerospace has developed an ultra-compact anti-jamming navigation solution for drones and unmanned systems, filed a related trademark, and entered the commercialization phase. Anti-jamming is a technology that maintains position and navigation information even in situations where Global Navigation Satellite System (GNSS) signals are disrupted. Since the outbreak of the war in Ukraine, it has emerged as a key countermeasure against the neutralization of drones.

According to the Intellectual Property Rights Information System on January 29, Hanwha Aerospace recently filed a domestic trademark application under the name 'LAGNAS.' The designated goods include navigation devices for drones, anti-jamming navigation devices, inertial measurement units (IMUs), and software for navigation systems, covering various navigation and anti-jamming related items. This move is interpreted as an intention to operate the anti-jamming solution as a product line and brand, rather than simply as a technical term.

LAGNAS is a system that miniaturizes Hanwha Aerospace's anti-jamming technology, which has been accumulated for guided missiles and vehicles, for application in drones, unmanned aerial vehicles (UAVs), and unmanned aerial systems (UAS). It is designed to enable drones to recognize their position and direction and continue flying even when GNSS signals are disrupted or difficult to receive.

A Hanwha Aerospace official stated, "Based on our experience developing anti-jamming technology for guided missiles and vehicles since 2020, and conducting military performance evaluations and deliveries in 2021, we have developed an ultra-compact anti-jamming system for drones and unmanned systems. LAGNAS underwent military-led performance tests starting in 2024 and completed performance verification in the first half of this year."

This trademark application is seen as a signal that the company has moved beyond the research and development stage and entered the commercialization phase. In the defense industry, it is common to establish product names and brands at the stage after performance verification, with mass production, deployment, and export in mind.

Since the war in Ukraine, GNSS jamming has been used as a key method for neutralizing drones, making anti-jamming technology an essential component for low-cost, mass-operated unmanned systems. Unlike conventional anti-jamming equipment focused on large weapon systems, demand is rapidly increasing for lightweight and cost-effective solutions that can be mounted on drones.
