How the Indian Navy's new GPS jammers could fool enemy missiles, drones and navigation systems

The Ministry of Defence has signed a declaration with a backstage steadfast for 20 enhanced capableness Global Navigation Satellite System (GNSS) jammers. Valued astatine Rs 449 crore, with 75% indigenous content, the woody falls nether the Buy Indian-Indigenously Designed, Developed and Manufactured (IDDM) category.

This marks a important measurement successful strengthening India’s maritime information and physics warfare capabilities.These jammers are designed to degrade an adversary GNSS receivers of systems specified arsenic specified arsenic the American GPS, European Galileo, China's BeiDou and the Russian GLONASSby disrupting outer signals and tin besides employment spoofing techniques to mislead force systems. Their induction volition heighten the Indian Navy’s quality to run safely successful multi-threat environments, wherever reliance connected GNSS is critical.Globally, modern militaries beryllium heavy connected GNSS for precision targeting, navigation, and communication. On land, GPS enables tracking of affable forces to forestall fratricide and helps amended accuracy of limb systems. Tactical networks trust connected GPS timing for synchronized communications.At sea, GPS integrates with inertial navigation to close drift, portion missiles beryllium connected GPS guidance. In aviation, GPS transforms unguided bombs into precision weapons done JDAM kits, guides UAVs via waypoints, and supports conjugation aerial postulation control.

India’s determination comes amid rising GPS interference and spoofing incidents, with implicit 465 cases reported betwixt 2023 and 2025 successful delicate aerial corridors specified arsenic Delhi, Amritsar and Jammu. Recently, a akin spoofing onslaught was carried retired during the sojourn of US Secretary of State Marco Rubio. Spoofing poses a superior threat, susceptible of misleading aircraft, undermining surveillance, and endangering civilian lives without nonstop confrontation.By deploying ECGNSS jammers, India is not lone countering these vulnerabilities but besides gathering indigenous expertise successful physics warfare. This inaugural strengthens deterrence, ensures operational resilience crossed land, sea, and air, and positions India to safeguard its aerospace and maritime domains against asymmetric threats.
