🕊️ Intro Whisper:

When satellites ride a shared spine, the sky becomes a space for many to dream.

🔹 Key Highlights: Satellite Bus as a Service (SBaaS) Initiative Launched by IN-SPACe

• Launched by: Indian National Space Promotion and Authorisation Centre (IN-SPACe)
• SBaaS = Satellite Bus as a Service
• Objective: Empower Indian private companies to develop modular satellite buses
• Target: Reduce import dependence & become a global provider of small satellite services

🧱 What is a Satellite Bus?

• The core structure of a satellite
• Supports power, thermal control, propulsion, communication
• Payload (camera, radar, sensors, etc.) rides atop the bus
• Like a universal chassis → allows flexibility for various missions

🧪 SBaaS Rollout – Phased Implementation

• Phase I:
  • Shortlist 4 Non-Governmental Entities (NGEs)
  • Develop modular, multi-mission satellite-bus platforms
• Phase II:
  • IN-SPACe to support 2 hosted-payload missions
  • Validate performance of the developed platforms in orbit

📤 Application & Timeline

• Open to eligible Indian NGEs
• Register by: May 15
• Proposal Deadline: June 23
• IN-SPACe acts as regulator + facilitator

🌍 Strategic Benefits

• Encourages Make in India for Space
• Reduces launch delays and development costs
• Supports start-ups & MSMEs in payload development
• Positions India as a service hub for hosted payloads globally

🧭 Concept Explainer:

Satellite Bus as a Service is like building a shared transport platform in orbit — allowing smaller companies to plug-and-play their ideas without building an entire satellite. It enables a future where space is modular, economical, and inclusive.

It’s not just about launching satellites — it’s about launching possibilities.

“When the backbone is shared, even the smallest payload can rise above the clouds.”
