Contract signed for GNSS jammers procurement for Navy, Pg10

Key Highlights:

• A contract worth ₹449 crore was signed for the procurement of 20 Enhanced Capability Global Navigation Satellite System (ECGNSS) Jammers for the Indian Navy.
• The contract was awarded to Bengaluru-based Accord Software and Systems Private Limited.
• This procurement falls under the 'Buy (Indian-Indigenously Designed, Developed and Manufactured)' (Buy (Indian-IDDM)) category, requiring a minimum of 75% indigenous content.
• The jammers are designed to degrade adversary satellite navigation signals and provide signal spoofing capabilities.
• The acquisition aims to significantly enhance the Indian Navy's electronic warfare capabilities and ensure operational safety in complex maritime environments.

Detailed Insights:

• The contract, signed on June 10, 2026, underscores the Indian government's commitment to the Aatmanirbhar Bharat and Make in India initiatives in defense manufacturing.
• ECGNSS Jammers are vital for protecting naval platforms by disrupting hostile navigation and targeting systems that rely on satellite-based positioning.
• These advanced systems will enable deceptive jamming operations, providing a crucial tactical advantage by misleading enemy forces regarding location and timing.
• The procurement is a significant step towards strengthening India's maritime security architecture and reducing reliance on foreign defense technologies.
• Accord Software and Systems Private Limited, an Indian company established in 1991, highlights the increasing contribution of domestic private industry to advanced defense technology development.

Scientific/Technical Concepts Involved:

• Global Navigation Satellite System (GNSS): A constellation of satellites providing global Positioning, Navigation, and Timing (PNT) services, such as GPS, GLONASS, Galileo, BeiDou, and India's NavIC.
• GNSS Jammers: Electronic devices that interfere with or block GNSS signals, preventing accurate positioning and timing information for adversary systems.
• Signal Spoofing: A deceptive electronic warfare technique where false GNSS signals are transmitted to mislead a receiver into calculating an incorrect position or time.
• Electronic Warfare (EW): Military action involving the use of electromagnetic energy to control the electromagnetic spectrum or attack an enemy, including jamming and deception.
