Navy Gets Advanced GNSS Jammers for Safe Sailing
10 Jun
Summary
- Indian Navy acquires advanced jammers to counter hostile satellite navigation.
- The ₹449 crore deal emphasizes indigenous design and development.
- New systems will ensure safe naval operations in complex conditions.

The Ministry of Defence has finalized a significant contract worth ₹449 crore for the procurement of 20 Enhanced Capability Global Navigation Satellite System (ECGNSS) Jammers for the Indian Navy. This acquisition, placed under the 'Buy (Indian-Indigenously Designed, Developed and Manufactured)' category, ensures a minimum of 75 per cent indigenous content, aligning with the government's 'Make-in-India' and 'Aatmanirbhar Bharat' initiatives.
The ECGNSS Jammers are sophisticated systems engineered to counteract hostile satellite navigation capabilities. Their functionalities include degrading an adversary's satellite signal acquisition and tracking, alongside capabilities for signal spoofing and deceptive jamming. The introduction of these jammers is anticipated to significantly bolster the maritime security architecture of India.
This procurement marks a critical milestone in bolstering the nation's defence capabilities and indigenizing advanced military technology. The systems are designed to support the safe operation of Indian Navy vessels, particularly in complex operational conditions and multi-threat environments, thereby reinforcing the country's maritime security.
