India is accelerating efforts to protect its territory from modern missile threats by building a space-based missile tracking and space situational awareness capability that integrates satellites, ground sensors and private-sector innovation. The move reflects growing recognition that future conflicts may be decided by who detects and responds to missile launches first, especially as hypersonic weapons and multiple warhead systems proliferate.
India space-based missile tracking
In a world where hypersonic missiles travel at many times the speed of sound and can follow unpredictable trajectories, seconds matter. Space-based infrared sensors can pick up the heat signature of a missile launch within moments, providing the earliest possible warning. That warning can give national leaders, military commanders and civil authorities the time to assess whether a launch is a test, a conventional strike or an escalation towards nuclear use.
Until recently, the United States led the field with a mature constellation of spaceborne infrared satellites that detect launches globally and fuse that data with terrestrial radars and naval sensors. China has been rapidly closing the gap, deploying early-warning satellites and long-range radars focused on the Asia-Pacific region to improve reaction times and secure its second-strike posture.
India faces a particular strategic challenge, sharing borders with two nuclear-armed neighbours and confronting a diverse threat environment that includes land-based, mobile and submarine-launched missiles. To meet those challenges, New Delhi is developing an integrated tracking architecture that combines ground-based radars, dedicated satellites and partnerships with private aerospace firms.
Bengaluru-based startup Digantara has emerged as a prominent private contributor to India’s space awareness efforts. After launching its initial SCOTI satellite in January 2025, the company plans to field a constellation of eye-in-the-sky satellites through 2027. Digantara’s roadmap includes advanced Albatross-class satellites in 2026 and 2027 designed to operate as intelligent sensors rather than simple cameras, detecting thermal signatures and refining probable missile trajectories.
Digantara pairs its space assets with a ground-support network known as Skygate. These ground telescopes and sensors act as continuous binoculars, tracking satellites and suspicious objects 24/7. Together, space and ground elements aim to provide a fused, near-real-time picture of launches and orbital activity, reducing the risk that debris or hostile action could blind India’s defences.
Investment in these capabilities is significant. Digantara has secured approximately $50 million (around INR 450 crore) and intends to expand its fleet to more than a dozen satellites, enhancing India’s indigenous capacity to monitor regional threats. The combination of private innovation and government support reflects a global trend of militaries leveraging commercial space technologies to speed capability development.
For policymakers and military planners, the primary benefit of a space-based missile tracking network is time: early detection narrows uncertainty, supports appropriate escalation control and enables civilian protection measures. In an era when missile launches can unfold in minutes or even seconds, space-based sensing is not a luxury but a national security imperative.
As India scales its capabilities, the country seeks to close the strategic gap with larger powers while ensuring its borders, people and critical infrastructure are better shielded from sudden missile threats. The coming years will show how rapidly a mix of public and private systems can be integrated to deliver reliable, resilient early warning for India and the region.
Key Takeaways:
- India is expanding space-based missile tracking and space situational awareness to detect hypersonic and other missile threats rapidly.
- Private firm Digantara has begun satellite launches and plans a constellation including Albatross-class sensors supported by ground-based Skygate systems.
- Early detection from space gives crucial seconds and minutes for decision-makers and civil defence, enhancing India’s deterrence and second-strike assurance.
