India’s Satellite Communications Sector: A Comprehensive Overview

Historical Evolution and Key Milestones

India’s satellite communications (satcom) journey began in the 1970s with pioneering efforts such as the 1975 Satellite Instructional Television Experiment (SITE), which used NASA’s ATS-6 satellite. This era also saw the launch of India’s first indigenously developed satellites, Aryabhata and the Rohini series. A major breakthrough came with APPLE (Ariane Passenger Payload Experiment) in 1981, ISRO’s first three-axis stabilized communication satellite.

This led to the commissioning of the Indian National Satellite (INSAT) system. While INSAT-1A (1982) failed early, INSAT-1B (1983) marked the start of a communications revolution in India. Through the 1980s–2000s, India deployed successive INSAT-1/2/3 series satellites for TV, radio, telephony, and meteorology.

With growing domestic capabilities, India launched the GSAT series from 2001 onwards, culminating in high-capacity satellites like GSAT-11 and GSAT-20. ISRO developed indigenous launch vehicles (SLV/ASLV → PSLV → GSLV) to place satellites into GEO. Recent milestones include ISRO’s SpaDeX mission (2024), which achieved India's first in-orbit satellite docking, and the upcoming launch of AST SpaceMobile’s Bluebird for direct-to-smartphone communication.

Today, ISRO operates one of Asia-Pacific’s largest communications satellite fleets, supporting TV broadcasting, V-SAT networks, secure communications, and more through C/Extended-C/Ku-band transponders.

Key Stakeholders: Government and Private Sector

Government Agencies:

• Department of Space (DoS)/ISRO: Designs, builds, launches, and manages India’s satellite fleet.

• NewSpace India Ltd (NSIL): The commercial arm marketing ISRO’s capacity (~11 satellites; ~10,000 MHz).

• Department of Telecommunications (DoT): Regulates licensing and policy, alongside WPC and TRAI.

• IN-SPACe: Authorizes private-sector space activities.

• Ministry of Information & Broadcasting (MIB): Regulates broadcasting services.

• Defense agencies (DRDO, NTRO): Utilize satcom for secure and intelligence applications.

  
  

Private Sector: India’s telcos are aggressively entering the satcom domain:

• Bharti Airtel merged its VSAT arm with Hughes to form HCIPL—India’s largest satellite broadband operator.

• Reliance Jio and SES formed Jio Space Technology Ltd to deploy GEO + MEO multi-orbit broadband.

• Eutelsat OneWeb India (Bharti-Vedanta JV) became the first authorized satellite broadband provider in 2023.

• Other players include Tata Sky, DishTV, Viasat, Raytheon, and startups like Pixxel and Agnikul Cosmos.

State-run BSNL uses satellite links for rural voice/data connectivity.

Regulatory Landscape and Reforms

Space Policy & Authorizations: The Indian Space Policy 2023 liberalized the sector, allowing Indian users to procure services from any source. IN-SPACe (May 2024) issued operational guidelines mandating authorizations for all space-based services.

Licensing and Spectrum: DoT and WPC oversee licensing. TRAI's 2022 recommendation led to the Satellite Earth Station Gateway (SESG) license—valid for 20 years and separate from the Unified License. The Telecom Act 2023 introduced administrative allocation for satellite spectrum. TRAI’s May 2025 spectrum assignment framework defines bands (Ku/Ka for NGSO FSS; L/S for MSS), tenure (5 years extendable), and pricing (ARMRC).

Ease of Doing Business: The 2022 Satellite Communication Reforms reduced license fees and procedural complexity. The Telecom Technology Development Fund (2025) aims to support indigenous satcom solutions for rural use.

Security and Compliance: DoT's 2025 GMPCS license conditions impose stringent security measures: data localization, traffic monitoring, terminal registration, geo-fencing, and NavIC integration by 2029. These impact foreign operators (e.g., Starlink, Kuiper) and raise compliance costs.

Technological Trends Driving Change

• Multi-Orbit & HTS: Jio-SES is deploying GEO+MEO constellations with SES’s HTS capabilities (e.g., SES-12, O3b mPOWER).

• Small Satellites: Cubesats and microsats in LEO reduce latency and costs; ISRO is preparing constellations for broadband IoT.

• Reusable Launchers: ISRO’s SSLV and RLV initiatives aim to reduce launch costs and turnaround times.

• Digital Payloads: Software-defined transponders allow in-orbit reconfiguration, boosting flexibility and efficiency.

• Other Innovations: ISRO’s SpaDeX success in autonomous docking, future plans for laser interlinks and space-based quantum communication signal next-gen capabilities.

  
  

Major Applications in India

• Telecommunications: Satcom bridges connectivity gaps in rural and remote regions. V-SAT backhaul, rural telephony, banking, and broadband via OneWeb/Starlink complement the Digital India initiative. AST SpaceMobile’s direct-to-smartphone satellite service (via NSIL) will soon enable non-terrestrial mobile coverage.

• Broadcasting and Media: C/Ku-band transponders on INSAT/GSAT support DTH TV (Tata Sky, DishTV), Doordarshan, FM radio, and news gathering across India—essential for pan-Indian content dissemination.

• Remote Sensing: India’s IRS/Cartosat/RISAT series satellites enable precision agriculture, urban planning, oceanography, and disaster management. While not part of satcom per se, these applications are integral to ISRO’s broader role in national development.

• Defense: Dedicated military satellites such as GSAT-7/Rukmini (Navy), GSAT-7A (Air Force), and the upcoming GSAT-7B (Army) provide secure, beyond-line-of-sight communication. Surveillance and SIGINT are supported by RISAT and EMISAT.

  
  

Sector Challenges

• Regulatory Complexity: Multiple agencies (DoT, WPC, IN-SPACe, MIB) create procedural delays.

• High Spectrum Fees: TRAI’s 4% revenue-based usage charge risks deterring private investment.

• Security Compliance: Localization, real-time monitoring, and NavIC integration increase operator burden.

• High Capital Requirements: Costs of manufacturing, launching, and setting up gateways remain significant.

• Technical Bottlenecks: Competition from terrestrial networks (fiber/5G), crowded spectrum, limited domestic capacity, and shortage of skilled workforce constrain scale.

  
  

Growth Drivers

• Rural Connectivity Demand: Nearly 40% of Indians lack internet access—satcom can fill this gap.

• Policy Liberalization: Space reforms and IN-SPACe guidelines encourage investment and private sector participation.

• Technological Progress: Lower-cost small sats, reusable launchers, and software-defined payloads improve ROI.

• Strategic Goals: Digital India, defense modernization, and strategic autonomy require robust satcom infrastructure.

• Private Investment and Partnerships: Collaborations like Airtel-Hughes and Jio-SES bring technology and scale. Global constellations paired with local deployment boost capabilities.

  
  

Conclusion

India’s satellite communications sector is undergoing a transformative phase, driven by liberalized policies, surging demand for connectivity, and rapid technological innovation. As broadband access becomes a national imperative, satellites are no longer niche infrastructure—they are emerging as mainstream enablers of India's digital economy and strategic autonomy.
