- DoT issued show cause notice
- Starlink halted pre-orders, now applying for license
Current Status (2026):
- Application pending
- Security concerns (China border areas, military implications)
- MHA clearance under review
5. Spectrum for Satellite Services
Spectrum Allocation Method: Administrative vs Auction
Telecom Operators' Demand:
- Spectrum for satellite broadband should be auctioned (like terrestrial 5G)
- Level playing field with terrestrial operators
Satellite Industry Position:
- Satellite spectrum allocated globally via ITU coordination
- Auction not feasible (interference management, international coordination)
- Administrative allocation is global norm
DoT/TRAI Position (2023):
- Spectrum for satellite services allocated administratively
- Not subject to auction
- ITU framework prevails
Satellite Frequency Bands
| Band | Frequency | Primary Use | Allocation Method |
|---|---|---|---|
| C-band | 4-8 GHz | VSAT, DTH (legacy) | Administrative |
| Ku-band | 12-18 GHz | DTH, VSAT, broadband | Administrative |

| S-band | 2-4 GHz | Mobile satellite, hybrid terrestrial-satellite | Administrative |
6. IN-SPACe and Space Sector Reforms
IN-SPACe (Indian National Space Promotion and Authorization Centre)
Role:
- Authorize private space activities (satellite launches, operations)
- Coordinate with DoT for spectrum allocation
- Promote commercial space sector
Impact on Satellite Communications:
- Faster approvals for satellite operators
- Streamlined process for foreign satellite services
- Coordination with DoT/TRAI for spectrum

12. Key Takeaways for Practitioners
Administrative Allocation Prevails: Satellite spectrum allocated administratively, not auctioned—ITU framework takes precedence over domestic auction policy.
LEO Constellations Pending: Starlink, OneWeb awaiting authorization—security clearance and gateway localization key hurdles.
GMPCS License Expensive: 15% AGR license fee (vs 8% for terrestrial)—reflects premium positioning and limited competition.
IN-SPACe Streamlines: New space regulator simplifies approvals—coordination with DoT improves timelines.
Security Paramount: Foreign satellite operators face stringent MHA clearance—data localization, lawful interception mandatory.
Rural Connectivity Driver: Satellite backhaul critical for BharatNet, USOF projects—government funding support available.
IFC Growing: In-flight connectivity via satellite gaining traction—airlines seeking better passenger experience.
Conclusion
Satellite communications in India stand at the cusp of transformation, with LEO constellations like Starlink and OneWeb promising global broadband coverage. The regulatory framework—DoT licensing, IN-SPACe coordination, administrative spectrum allocation—balances innovation with security concerns. The 2023 decision to administratively allocate satellite spectrum (not auction) aligns India with global ITU practices but faces opposition from terrestrial telecom operators seeking a level playing field. GMPCS, VSAT, and DTH services continue to serve niche markets, while satellite backhaul becomes critical for rural connectivity under USOF. Practitioners must navigate licensing complexities, MHA security clearances, and data localization requirements while advising clients on emerging opportunities in LEO broadband, in-flight connectivity, and maritime communications.
