Overview
The Ministry of Defence signed a ?449 crore contract on 10 June 2026 with Bengaluru-based Accord Software for 20 indigenous GNSS jammers for the Indian Navy. The equipment, made with 75% local content, will disrupt enemy satellite navigation, boosting maritime security and supporting Aatmanirbhar Bharat.
A Big Step for Navy’s Electronic Warfare
On 10 June 2026, the Ministry of Defence (MoD) signed a contract worth ?449 crore. The contract is with Accord Software and Systems Private Limited (ASSPL) from Bengaluru. Under this deal, the company will supply 20 Enhanced Capability Global Navigation Satellite System (ECGNSS) Jammers to the Indian Navy. These jammers are advanced electronic warfare systems. They can block or confuse satellite navigation signals used by enemy ships, aircraft, and missiles. The contract was signed under the Buy (Indian-IDDM) category. This means the jammers are designed, developed, and manufactured in India. The project requires at least 75% indigenous content. This is a big boost for India’s defence manufacturing and self-reliance.
What Are GNSS Jammers?
GNSS stands for Global Navigation Satellite System. These systems include the US GPS, Russian GLONASS, European Galileo, and Chinese BeiDou. Many modern weapons use these signals to find their targets. A GNSS jammer is a device that sends out radio signals. These signals overpower the real satellite signals. As a result, enemy receivers cannot lock onto satellites. They lose navigation and targeting ability. The ECGNSS jammers for the Indian Navy can do more than just block. They can also send fake signals to confuse the enemy. This is called spoofing.
Key Features of the ECGNSS Jammers
The jammers are designed to:
-
Degrade satellite signal acquisition – make it hard for enemy to find satellites.
-
Interfere with signal tracking – cause navigation errors.
-
Perform signal spoofing – send false location data.
-
Counter adversary navigation systems – protect Indian ships from guided threats.
These capabilities give the Indian Navy a strong defensive and offensive electronic warfare tool.
Why Does the Indian Navy Need These Jammers?
The Indian Ocean is a very important region. Many countries have naval forces there. China and Pakistan are modernising their navies. They have missiles and drones that use satellite guidance. Without GNSS jammers, Indian warships are vulnerable. With these jammers, the Navy can:
-
Protect its ships from enemy missiles.
-
Disrupt enemy communications and navigation.
-
Operate without being tracked.
-
Enhance overall maritime security.
The 20 jammers will be placed on key frontline warships. These include destroyers, frigates, and aircraft carriers.
Aatmanirbhar Bharat and Make in India
This contract is a perfect example of the government’s Aatmanirbhar Bharat (Self-Reliant India) policy. Instead of buying jammers from other countries, the MoD chose an Indian company. Accord Software and Systems is a Bengaluru-based firm. It specialises in navigation and communication systems. By designing and making these jammers in India, the country reduces dependence on foreign suppliers. The 75% indigenous content rule means that many small and medium businesses also benefit. They supply parts and services for the jammers. This creates jobs and builds technical skills.
About Accord Software and Systems
Accord Software and Systems Private Limited (ASSPL) is an Indian company. Its headquarters is in Bengaluru, Karnataka. The company works on satellite navigation, communication, and electronic warfare systems. It has developed many products for India’s defence forces. This contract shows that Indian companies can make high-tech defence equipment. It also encourages other Indian firms to develop indigenous products.
A Human Touch: The Engineers Behind the Jammers
Behind every defence product are hardworking engineers and technicians. Many young graduates from Indian Institutes of Technology (IITs) and National Institutes of Technology (NITs) worked on these jammers. A senior engineer at Accord said, “We started from scratch. We did not copy anything. We designed every circuit ourselves. Seeing our jammer go into the Navy is a proud moment for every Indian.” Such stories show that defence contracts are not just about money. They are about national pride and technological self-reliance.
How Will the Jammers Be Used?
The ECGNSS jammers will be integrated with the Navy’s existing electronic warfare systems. They can be used in both defence and offence. During peacetime, they remain on standby. During tensions or war, they can be activated to create a “navigation blackout” for enemy forces. The jammers are built to work in harsh sea conditions. They can handle saltwater, high humidity, and strong vibrations. Their size is compact. They can be fitted on different classes of ships without major changes.
Future of Indigenous Defence Electronics
This contract is likely the start of more such deals. The Indian Navy is growing. It is getting new ships, submarines, and aircraft. Every new platform needs electronic warfare protection. The success of these indigenous jammers could lead to more orders for Accord and other Indian companies. It could also open export opportunities. Friendly countries may want to buy similar jammers from India.
