Background: India’s Space Security Evolution

Historical Context of Satellite Threats

India’s space program has long operated under the shadow of potential threats from neighboring countries. The nation has engaged in multiple armed conflicts over seven decades with both Pakistan and China, nations possessing vastly different space capabilities. Pakistan operates merely eight satellites compared to India’s impressive fleet of over 100, while China maintains a formidable presence with more than 930 satellites.

The growing militarization of space became evident during recent tensions between India and Pakistan in May 2025, when satellites played a crucial role in the conflict. During Operation Sindoor, over 400 ISRO scientists worked around the clock to provide real-time Earth observation and communication support. Reports suggest that China aided Pakistan by adjusting its satellite coverage during this period, demonstrating the asymmetric threats India faces in space.

Rising Orbital Congestion

The Low Earth Orbit (LEO) environment, particularly at altitudes of 500-600 kilometers where the near-miss occurred, is becoming increasingly congested. This region hosts numerous commercial constellations, including Elon Musk’s Starlink network, creating a complex operational environment where satellites must navigate through dense traffic.

ISRO’s Indian Space Situational Assessment Report (ISSAR) for 2024 reveals the agency performed 10 Collision Avoidance Manoeuvres (CAMs) to protect its satellites from potential collisions. The space agency issued over 53,000 alerts for potential collisions throughout 2024, demonstrating the scale of orbital traffic management required.

Core Analysis: The Mid-2024 Near-Miss Incident

Details of the Orbital Encounter

The previously unreported incident in mid-2024 involved an ISRO satellite performing critical tasks with potential military applications, including mapping and ground monitoring. The foreign spacecraft, from an unnamed neighboring country, approached dangerously close in the increasingly crowded LEO environment at 500-600 kilometers altitude. slguardian

Although no collision occurred, the unusually close approach of one kilometer was interpreted by defense analysts as a possible demonstration of capability or show of strength. The incident highlighted India’s vulnerability to hostile maneuvers in orbit and the need for enhanced protective measures.

Strategic Implications and Threat Assessment

The near-miss exposed critical gaps in India’s space situational awareness capabilities. Sudheer Kumar N, a former ISRO director now working as an independent consultant, acknowledged that “we currently lack round-the-clock in-orbit tracking capabilities”. This limitation becomes particularly concerning given China’s rapid expansion of space-based surveillance assets.

Chinese military officials and U.S. defense experts have warned about the growing threat from China’s People’s Liberation Army in space. Air Marshal Ashutosh Dixit cautioned in June 2024 that Beijing’s satellite program has grown rapidly in both scale and sophistication, posing significant risks to other nations including India.

India’s Bodyguard Satellite Program

Concept and Objectives

India’s bodyguard satellites represent a revolutionary approach to orbital security, designed to act as vigilant sentinels protecting critical space assets. These spacecraft will feature advanced sensors and high-level maneuverability, positioned to provide real-time threat detection and rapid response capabilities. spaceanddefense

The bodyguard concept involves specialized spacecraft that can detect, identify, and counter threats to valuable satellites through various means including surveillance, electronic warfare, and if necessary, physical intervention. These systems are designed to provide “reversible attacks” – temporary disruption of hostile spacecraft without permanent damage, serving as a de-escalation strategy. spaceanddefense

Integration of Advanced Technologies

The program will incorporate cutting-edge Light Detection and Ranging (LiDAR) technology to generate precise 3D maps of nearby orbital objects. LiDAR-equipped satellites can detect threats faster and more accurately than conventional radar systems, providing crucial time for ground teams to maneuver protected assets out of harm’s way.

The bodyguard satellites will be integrated with an enhanced ground-based tracking network, including upgraded radars and optical telescopes, creating a comprehensive space surveillance system. This multi-layered approach ensures continuous monitoring and the ability to respond quickly to emerging threats.

Government’s Broader Space Initiative

Prime Minister Narendra Modi’s government has approved a comprehensive 270 billion rupee ($3 billion) plan to deploy approximately 50 surveillance satellites. This initiative, part of the Space-Based Surveillance Phase III (SBS-III) program, represents one of the most ambitious space security projects in India’s history.

The SBS-III program involves construction and launch of 21 satellites by ISRO and 31 by three private companies. Following Operation Sindoor, the timeline has been accelerated, with the first satellite now expected to launch by April 2026 instead of the original 2027 timeline.
