Ministry of Defence Signs Contract for 20 ECGNSS Jammers for Indian Navy

The Ministry of Defence signs a contract to procure 20 Enhanced Capability Global Navigation Satellite System (ECGNSS) jammers for the Indian Navy. The contract covers indigenously designed, developed, and manufactured electronic warfare systems that disrupt, degrade, or deceive hostile satellite navigation signals.

Enhanced Capability Global Navigation Satellite System (ECGNSS) Jammers :

Dimension	Key Details
System Type	ECGNSS refers to advanced, mobile electronic warfare systems designed to disrupt, degrade, or deceive hostile satellite navigation signals by jamming and spoofing.
Signal Jamming	Signal jamming means blocking wireless communication by sending strong interference signals on the same frequency, creating a localized dead zone where legitimate signals cannot transmit or receive data.
Signal Spoofing	Signal spoofing is a cyberattack where a transmitter broadcasts counterfeit radio signals to trick a receiver into trusting false data.
Developer	The ECGNSS jammers are developed by Accord Software and Systems Pvt. Ltd.
Key Feature: Deceptive Jamming and Spoofing	The systems specialise in signal spoofing by broadcasting false satellite signals that deceive hostile receivers into calculating incorrect positioning, navigation, and timing (PNT) data.
Electronic Warfare Role	The ECGNSS jammers authorise soft-kill offensive and defensive measures by blinding anti-ship precision-guided munitions (PGMs) before they reach local airspace.
Technology and Indigenous Content	The systems are indigenously designed, developed, and manufactured, and comprise a minimum of 75% indigenous content.
Stated Alignment	The procurement aligns with Aatmanirbhar Bharat and Make-in-India initiatives.
Maritime Security Relevance	The systems strengthen electronic warfare capabilities of Indian Navy ships.
Broad Spectrum Denial Coverage	The jammers are engineered to degrade signal acquisition and satellite tracking performance of major GNSS architectures: GPS (United States), GLONASS (Russia), BeiDou (China), and Galileo (European Union).
