India is undertaking an ambitious satellite expansion program to bolster national security and border monitoring capabilities. According to Mr. Pawan Kumar Goenka, Chairman of the Indian National Space Promotion and Authorisation Centre (IN-SPACe), the country will launch 52 satellites over the next five years. This mission, announced during the Global Space Exploration Conference 2025, marks a significant milestone in India’s space journey—one that integrates public-private collaboration to ensure a more secure and connected nation.

Strengthening Defence Capabilities through Satellite Surveillance

At the core of this strategy is the intention to enhance surveillance capabilities of the Indian Army, Navy, and Air Force. The planned satellite constellation will enable:

• Tracking of enemy troop movements and military build-ups.

• Monitoring of international borders and maritime boundaries in real-time.

• Improved coordination during military operations through high-resolution imagery and data.

This significant leap in satellite infrastructure aims to provide comprehensive space-based reconnaissance, especially critical for high-conflict zones and sensitive border regions.

A Balanced Role Between ISRO and Private Sector

One of the most progressive features of this initiative is the equitable involvement of private players. As Mr. Goenka stated, 50% of the satellites will be developed by private companies, while the remaining will be managed by the Indian Space Research Organisation (ISRO).

This shift towards private sector participation marks a turning point in India's space policy. The integration of agile startups and experienced private aerospace firms is expected to:

• Accelerate innovation in satellite technology.

• Reduce development timelines and cost overruns.

• Promote a more competitive ecosystem for space manufacturing and services.

IN-SPACe: The Driving Force Behind Space Authorisation and Facilitation

IN-SPACe, which oversees private sector participation in space, is playing a pivotal role in enabling private enterprises to contribute towards strategic projects. While Mr. Goenka lauded the centre’s current capabilities, he also emphasised the need for continuous enhancement in expertise and infrastructure.

Additionally, the final implementation and operational priorities for satellite surveillance will rest with the Union Home Ministry and the Indian defence forces. This ensures that the defence imperatives drive technological decisions and satellite deployment timelines.

SSLV Technology Transfer: A Critical Enabler for Rapid Launches

Complementing the satellite constellation initiative is the transfer of Small Satellite Launch Vehicle (SSLV) technology to the private sector. This move is vital for ensuring that India can rapidly launch satellites—especially in emergency defence scenarios such as during border skirmishes or natural disasters.

The SSLV, developed by ISRO, is designed to:

• Launch satellites weighing between 10 to 500 kilograms.

• Insert payloads into 500-kilometre low earth orbits (LEO).

• Offer on-demand launch capabilities.

• Minimise ground infrastructure requirements.

• Maintain low operational costs and faster turnaround times.

Mr. Goenka hinted that the official transfer of SSLV technology to private players may be announced within a fortnight, signifying imminent action in this domain.

Why Surveillance Satellites Are Critical for India

The necessity of a robust satellite surveillance system is becoming increasingly evident due to:

• Geopolitical tensions along India’s borders with Pakistan and China.

• Rising maritime threats in the Indian Ocean Region (IOR).

• Growing concerns over cyber and hybrid warfare.

• The need for real-time intelligence during counter-terrorism operations.

India currently relies on a limited number of remote sensing and reconnaissance satellites, often not enough to provide persistent coverage of all critical zones. The launch of 52 satellites will help plug this gap significantly.

Role of Private Companies in India’s Space Vision

With ISRO focusing more on research, innovation, and policy leadership, the baton of execution and scale is increasingly being handed over to private enterprises. The following categories of companies are likely to benefit:

• Satellite manufacturing startups such as Pixxel and Dhruva Space.

• Private launch vehicle developers including Agnikul Cosmos and Skyroot Aerospace.

• Data analytics and space applications firms that offer solutions for defence, agriculture, and disaster management.

The active involvement of the private space ecosystem is expected to stimulate new investments and employment while delivering cutting-edge technology to India's armed forces.

India’s Global Stand in Space-Based Defence

India’s move aligns with global trends where countries like the United States (via SpaceX and Palantir), China (through CASC and private players), and Russia are heavily investing in military satellite networks. India’s plan to launch 52 satellites puts it in the league of top space-faring nations focused on national security.

Moreover, the inclusion of launch-on-demand capabilities via SSLV will allow India to respond swiftly to threats or satellite failures—ensuring uninterrupted surveillance coverage.

Policy and Regulatory Implications

This mission is not just a technological advancement but also a policy-driven breakthrough. The growing role of IN-SPACe reflects the Indian government's shift towards:

• Liberalising the space sector.

• Creating an open, secure, and scalable ecosystem.

• Encouraging foreign and domestic investments in high-tech space innovation.

With defence needs driving technology development, we can expect greater coordination between the Ministry of Defence, IN-SPACe, ISRO, and private players.

Conclusion

India’s decision to launch a constellation of 52 satellites for defence surveillance over the next five years reflects strategic foresight and technological ambition. It will not only strengthen the nation’s defence capabilities but also empower the private sector, drive innovation, and ensure resilience against modern-day threats.

The upcoming SSLV technology transfer is another major milestone that will enhance India's rapid launch capabilities. As the world increasingly relies on space for security, communication, and intelligence, India’s initiative positions it as a key global player in the space-defence nexus.
