Context
The Indian Space Research Organisation (ISRO) has signed its 100th technology transfer agreement with Hindustan Aeronautics Limited (HAL). This landmark deal empowers HAL to undertake the independent production of Small Satellite Launch Vehicles (SSLVs). The development strengthens India’s efforts toward Atmanirbhar Bharat and expands its role in the global space economy.
About ISRO’s 100th Technology Transfer with HAL
- Marks ISRO’s 100th successful technology transfer milestone.
- Enables HAL to manufacture SSLVs without direct ISRO support.
- Promotes indigenisation of critical space technology and strengthens the public–industry partnership.
About Small Satellite Launch Vehicle (SSLV)
What it is
- A 3-stage, low-cost launch vehicle designed for small satellite deployment.
- Configured with three solid propulsion stages and a liquid-based Velocity Trimming Module (VTM).
- Developed by ISRO to meet the growing demand for quick, flexible, and affordable satellite launches.
Objectives
- To cater to the global small satellite market.
- To provide launch-on-demand services with minimal infrastructure.
- To ensure faster turnaround time for satellite launches.
Specifications
- Height: ~34 meters (equivalent to an 11-storey building).
- Diameter: ~2 meters.
- Lift-off Weight: Around 120 tonnes.
- Payload Capacity: Up to 500 kg of satellites in a 500 km orbit.
Engines & Propulsion
- First Stage: Solid fuel.
- Second Stage: Solid fuel.
- Third Stage: Solid fuel.
- Final Stage (VTM): Small liquid-fuel engines (MMH + MON-3) with 16 micro-thrusters (50 N each) for precise orbit placement.
Capabilities
- Can launch single or multiple satellites in one mission.
- Optimised for nanosatellites, microsatellites, and minisatellites (10–500 kg).
- Provides flexible, quick, and cost-effective launch solutions for domestic and international clients.
Significance of the ISRO–HAL Agreement
- Boosts Atmanirbhar Bharat: HAL gains the capacity to independently manufacture SSLVs.
- Strengthens Industrial Ecosystem: Expands the role of Indian public and private industries in the space sector.
- Enhances Commercial Competitiveness: Positions India as a strong player in the global small-satellite launch market.
- Symbolic Milestone: Reflects ISRO’s 100th technology transfer, showcasing successful innovation-to-industry integration.
Conclusion
The ISRO–HAL agreement for SSLV production is a turning point in India’s space journey. It not only strengthens technological self-reliance but also enhances India’s global standing in satellite launch services, ensuring that the country remains a key player in the expanding space economy.
