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

How the Indian Navy's new GPS jammers could fool enemy missiles, drones and navigation systems The Ministry of Defence has signed a contract with a private firm for 20 enhanced capability Global Navigation Satellite System (GNSS) jammers. Valued at Rs 449 crore, with 75% indigenous content, the deal falls under the Buy Indian-Indigenously Designed, Developed and Manufactured (IDDM) category. This marks a significant step in strengthening India’s maritime security and electronic warfare capabilities.These jammers are designed to degrade an adversary GNSS receivers of systems such as such as the American GPS, European Galileo, China's BeiDou and the Russian GLONASSby disrupting satellite signals and can also employ spoofing techniques to mislead enemy systems. Their induction will enhance the Indian Navy’s ability to operate safely in multi-threat environments, where reliance on GNSS is critical.Globally, modern militaries depend heavily on GNSS for precision targeting, navigation, and communication. On land, GPS enables tracking of friendly forces to prevent fratricide and helps improve accuracy of weapon systems. Tactical networks rely on GPS timing for synchronized communications.At sea, GPS integrates with inertial navigation to correct drift, while missiles depend on GPS guidance. In aviation, GPS transforms unguided bombs into precision weapons through JDAM kits, guides UAVs via waypoints, and supports coalition air traffic control. End of Article
