Indian Space Research Organisation (ISRO) Chairman S. Somanath announced that the country will add between 100 and 150 satellites to its orbital fleet over the next three years. The ambitious expansion, he said, is aimed at enhancing national security, disaster management, and public safety across multiple sectors.
Speaking at a defence and aerospace conclave in Bengaluru, Somanath emphasized the critical role of space technology in India’s strategic and civil development goals. “Our focus is on building a robust space ecosystem that can offer real-time data, advanced surveillance, and secure communication channels to support the country’s safety and development missions,” he said.
Strategic Shift: From Launches to Constellations
India currently operates around 50 active satellites in various orbits for communication, navigation, earth observation, and scientific research. The proposed addition marks a paradigm shift—from individual high-value satellites to compact, cost-effective satellite constellations that work in coordinated networks.
“Earlier, we were launching big satellites every few months,” Somanath explained. “Now, we are working towards deploying multiple constellations—miniature satellites that can offer better coverage, more frequent updates, and redundancy during emergencies.”
This strategy mirrors the global shift towards satellite constellations, a model used by companies like SpaceX and OneWeb. However, India’s approach is expected to be more integrated with national needs, including internal security, border monitoring, agriculture, disaster relief, and urban planning.
Defence and Disaster Response at the Forefront
According to ISRO officials, a significant portion of these upcoming satellites will cater to India’s strategic and security interests. These include:
- Surveillance satellites capable of monitoring border activities and troop movements in real-time, especially along sensitive regions like Ladakh, Arunachal Pradesh, and coastal belts.
- Communication satellites to support the armed forces in high-altitude and remote terrains.
- Synthetic Aperture Radar (SAR) satellites, which can penetrate cloud cover and provide clear imagery even during night-time and adverse weather conditions.
ISRO also plans to expand its fleet of disaster-monitoring satellites to assist the National Disaster Response Force (NDRF) and state authorities with real-time alerts on cyclones, floods, earthquakes, and wildfires.
Somanath added, “The space-based alert systems have already saved lives during recent cyclones in the Bay of Bengal. With more satellites, we can ensure quicker, more accurate warnings and response mechanisms.”
Civilian Applications: From Farming to 5G
While national security remains a top priority, the satellite expansion will also benefit civilian sectors. Satellite imaging will be used to track crop health, groundwater levels, and deforestation, providing vital data to farmers and environmental agencies.
Additionally, low-Earth orbit (LEO) satellites will assist in delivering high-speed internet in rural and hilly areas, supporting India’s Digital India and BharatNet missions. “Imagine a future where students in Ladakh have the same connectivity as those in Bengaluru—that’s what we’re aiming for,” said the ISRO chief.
These efforts will be supported by collaborations with private players under the Indian National Space Promotion and Authorization Center (IN-SPACe), which allows startups and private companies to participate in satellite launches and development.
Challenges and the Way Forward
Despite the grand vision, challenges remain. Launch vehicle capacity, frequency of launches, and global space traffic management are significant concerns. ISRO is working on enhancing the GSLV Mk III and developing next-generation launch vehicles with higher payload capabilities.
Moreover, India is actively participating in global dialogues to prevent satellite collisions and manage the growing issue of space debris.
Somanath concluded by stressing the need for greater coordination between space, defence, and civil agencies. “Space is no longer just about exploration—it’s about protection, empowerment, and preparedness. Our goal is to build a space ecosystem that strengthens India in every dimension—on land, in the air, and above the skies.”
Conclusion: A Safer, Smarter Sky
With this visionary satellite push, India is preparing not just to observe the earth but to safeguard it. The move reflects a nation ready to harness cutting-edge technology for both strategic edge and societal upliftment. As ISRO accelerates its countdown toward a more secure and connected India, the sky is no longer the limit—it’s the frontline.
