The Indian Army's operational effectiveness is set to receive a boost with the introduction of SANJAY, a state-of-the-art battlefield surveillance system. Developed through a collaboration with Bharat Electronics Limited (BEL), a public sector unit, Sanjay integrates data from various aerial and terrestrial sensors to create a cohesive and unified view of the battlefield.
This integrated approach enhances precision, eliminates data redundancy and streamlines the utilization of the Army Data Network and Satellite Communication Network.
Equipped with advanced sensors and analytics, Sanjay can monitor extensive land borders, including strategically important areas such as the Line of Actual Control with China. The system is designed to deliver real-time, precise intelligence to the Indian Army Command, facilitating quicker and better-informed decisions.

SANJAY Advanced Battlefield Surveillance System
The SANJAY Battlefield Surveillance System (BSS) is an advanced, integrated surveillance system developed indigenously by the Indian Army in collaboration with Bharat Electronics Limited (BEL). This system is designed to provide the Indian Army with enhanced battlefield transparency through the integration of data from various ground and aerial sensors. By processing and fusing inputs, SANJAY delivers a comprehensive surveillance picture across secured Army Data and Satellite Communication Networks, enhancing situational awareness for commanders.
Key Features of the SANJAY System
- Integration of Sensors: SANJAY integrates inputs from both ground and aerial battlefield sensors to create a comprehensive surveillance picture.
- Advanced Analytics: Equipped with state-of-the-art sensors and cutting-edge analytics for accurate situation assessment.
- Network Centricity: Facilitates operations in conventional and sub-conventional scenarios within a network-centric environment.
- Enhanced Transparency: Significantly improves battlefield transparency, providing real-time inputs to Command & Army Headquarters.
- Centralized Web Application: Transforms battlefield management through a centralized web application that supports the Indian Army Decision Support System.
- Indigenous Development: Jointly developed by the Indian Army and Bharat Electronics Limited (BEL), emphasizing indigenous technology.
Significance of the SANJAY System

The induction of the SANJAY system marks a significant leap towards data and network centricity in the Indian Army, enhancing battlefield transparency and transforming future battlefield operations through its centralized web application. It enables commanders to operate effectively in both conventional and sub-conventional scenarios by providing real-time intelligence and reconnaissance.
According to sources within the Indian Army, the Sanjay system is expected to significantly alter how commanders manage both traditional and unconventional military actions. With its integrated artificial intelligence (AI), Sanjay can evaluate real-time battlefield situations, offering crucial surveillance data for troop positioning, accurate targeting, and other key strategic choices. This functionality enhances the system's role as a substantial force multiplier, aiding in the prevention of border incursions and delivering unparalleled situational awareness.
The implementation of Sanjay will be carried out in three stages, starting in March and finishing by October 2025, across the Army’s operational units. The Ministry of Defence has declared this period the ‘Year of Reforms’.
Operational Advantages
- Enhanced Situational Awareness: By integrating data from multiple sensors, SANJAY provides a comprehensive and real-time view of the battlefield, enabling commanders to make informed decisions.
- Improved Coordination: The network-centric environment facilitates better coordination between different units and command centres, enhancing overall operational effectiveness.
- Early Warning: Advanced radar systems like the Rohini and Ashwini provide early warning capabilities for air defense, allowing for timely responses to potential threats.
- Versatile Deployment: Systems like the BFSR-SR are man-portable and can be quickly deployed in various terrains, providing flexible surveillance options.

Integration with Other Systems
The effectiveness of the SANJAY system is further enhanced through its integration with other key systems and technologies within the Indian Army.
- Akash Weapon System: The radar serves as the primary sensor for the Akash surface-to-air missile system, providing extensive search and tracking capabilities for multiple targets and missiles.
- Hand-Held Thermal Imagers (HHTIs): Newer variants of battlefield surveillance radars are being networked with HHTIs for visually tracking targets detected by the radar, improving the overall efficacy of the system.
- Artillery Systems: Battlefield surveillance radars support artillery units by locating shell bursts and providing fire correction data, enhancing the accuracy and effectiveness of artillery fire.
Challenges and Future Directions
While the SANJAY system represents a significant advancement in battlefield surveillance capabilities, there are challenges to address and opportunities for future development.
- Data Overload: Integrating data from multiple sensors can lead to information overload. Effective data management and prioritization are crucial to ensure that commanders receive timely and relevant information.
- Cybersecurity: As a network-centric system, SANJAY is vulnerable to cyber threats. Robust cybersecurity measures are essential to protect the system from unauthorized access and disruption.
- Technological Upgradation: Continuous technological advancements are necessary to maintain a competitive edge. Future developments should focus on enhancing sensor capabilities, improving data analytics, and incorporating artificial intelligence and machine learning technologies.
The SANJAY Battlefield Surveillance System represents a significant step forward in enhancing the Indian Army's surveillance capabilities. By integrating advanced sensors, communication networks, and data analytics, SANJAY provides commanders with a comprehensive and real-time view of the battlefield, enabling them to make informed decisions and respond effectively to emerging threats.
As technology continues to evolve, ongoing development and integration efforts will be crucial to maintaining the system's effectiveness and ensuring that the Indian Army remains at the forefront of battlefield surveillance technology.
