3. Commercial Viability: SpaceX’s proven track record in launching heavy payloads, coupled with competitive pricing, made it the preferred choice for this critical mission.

Technical Highlights of GSAT-N2

• Weight: 4,700 kg
• Capacity: Ka-Band HTS with a throughput of 48 Gbps
• Coverage: Nationwide, with a focused emphasis on Northeast India through specialized spot beams
• Operational Lifespan: 14 years
• Ground Infrastructure: Supported by hub stations throughout India to ensure stable connectivity.

The Growing Importance of International Collaborations

The launch of GSAT-N2 is a clear indicator of India’s shifting strategy towards international collaborations to achieve its space and technological goals. Historically, ISRO has relied heavily on indigenous capabilities and traditional European partners like Arianespace for satellite launches. However, the collaboration with SpaceX opens up new avenues for:

1. Access to Advanced Technologies: SpaceX’s cutting-edge launch vehicles, including the Falcon 9, provide India with access to advanced launch technologies.
2. Cost-Effective Solutions: Partnering with SpaceX offers competitive pricing, essential for missions with heavy or complex payloads.
3. Expanding Opportunities: The success of this mission sets a precedent for future collaborations, enhancing India’s position in the global space industry.
