Indigenous GNSS jammers for Indian Navy receive a major boost as the Ministry of Defence signs a ₹449 crore contract under the IDDM category. Learn about ECGNSS jammers, electronic warfare, Aatmanirbhar Bharat, and key exam facts.
Introduction
India has taken another significant step towards strengthening its maritime defence capabilities and achieving self-reliance in defence manufacturing. The Ministry of Defence (MoD) has signed a contract worth ₹449 crore with a Bengaluru-based defence technology company for the procurement of 20 Enhanced Capability Global Navigation Satellite System (ECGNSS) Jammers for the Indian Navy. The acquisition is aimed at improving the Navy’s electronic warfare capabilities and enhancing operational security in modern combat environments.
What is the New Defence Contract?
The Ministry of Defence signed the agreement with Accord Software and Systems Private Limited (ASSPL), Bengaluru, for the supply of 20 ECGNSS jammers. The contract has been concluded under the ‘Buy Indian – Indigenously Designed, Developed and Manufactured (IDDM)’ category, which promotes indigenous defence production. A key feature of the project is that the equipment will contain at least 75% indigenous content.
Understanding GNSS and GNSS Jammers
Global Navigation Satellite Systems (GNSS) are satellite-based navigation systems that provide positioning, navigation, and timing services. Popular GNSS systems include GPS (United States), GLONASS (Russia), Galileo (European Union), and BeiDou (China).
A GNSS jammer is an electronic warfare system designed to interfere with or block satellite navigation signals. Such systems can prevent enemy missiles, drones, aircraft, or ships from accurately determining their position, thereby reducing their effectiveness during military operations.
Importance for the Indian Navy
The procurement of advanced GNSS jammers will significantly strengthen the Indian Navy’s ability to operate in contested maritime environments. These systems can help naval platforms disrupt hostile navigation signals and improve survivability during combat operations.
The jammers are expected to play an important role in safeguarding naval assets, protecting strategic sea lanes, and enhancing electronic warfare preparedness. In an era where precision-guided weapons and autonomous drones rely heavily on satellite navigation, such technologies have become essential for modern naval warfare.
Boost to Indigenous Defence Manufacturing
The contract highlights India’s growing emphasis on the “Aatmanirbhar Bharat” initiative in the defence sector. The requirement of 75% indigenous content ensures that a large portion of the manufacturing, design, and development process remains within the country.
This initiative not only strengthens national security but also promotes domestic industries, generates employment opportunities, and reduces dependence on foreign defence imports. The Department of Defence Production has consistently emphasized self-reliance in defence manufacturing as a national priority.
Role of Electronic Warfare in Modern Military Operations
Electronic warfare has become a crucial component of modern defence strategy. It involves the use of electromagnetic spectrum technologies to detect, disrupt, deceive, or destroy enemy systems.
GNSS jammers represent a critical electronic warfare capability because they can interfere with satellite-based navigation systems that guide missiles, drones, and military vehicles. As modern warfare increasingly depends on precision-guided technologies, countries are investing heavily in electronic warfare systems to gain tactical advantages on the battlefield.
Strategic Significance for India
India faces complex security challenges in the Indian Ocean Region and along its maritime boundaries. The acquisition of indigenous GNSS jammers strengthens the Navy’s ability to protect strategic interests and maintain operational superiority.
The move also demonstrates India’s commitment to developing advanced defence technologies domestically while modernizing its armed forces. Such acquisitions contribute to long-term military preparedness and technological independence.

Historical Context
Evolution of India’s Defence Indigenization
For decades, India relied heavily on foreign suppliers for advanced military equipment. However, concerns regarding strategic autonomy and supply chain vulnerabilities encouraged policymakers to promote indigenous defence manufacturing.
Make in India and Defence Reforms
The Government of India launched the Make in India initiative in 2014, followed by several reforms in defence procurement. The IDDM category was introduced to prioritize equipment that is designed, developed, and manufactured within India.
Rise of Electronic Warfare Systems
Modern military conflicts have demonstrated the importance of electronic warfare. Countries increasingly deploy jamming, spoofing, and cyber-electronic systems to disrupt enemy communications and navigation networks.
Indian Navy Modernization
The Indian Navy has been pursuing a comprehensive modernization program that includes indigenous warships, submarines, missiles, aircraft carriers, surveillance systems, and electronic warfare equipment. The acquisition of ECGNSS jammers is another milestone in this modernization effort.
