Jio’s 1,600-Satellite LEO Constellation Gets Technical Green Light

Reliance Jio has crossed a significant milestone in its space connectivity ambitions after its proposal to deploy a Low Earth Orbit (LEO) satellite constellation of around 1,600 satellites received a positive technical assessment from the Indian National Space Promotion and Authorisation Centre (IN-SPACe).

The evaluation, conducted jointly by IN-SPACe, the Indian Space Research Organisation (ISRO), and the Wireless Planning and Coordination (WPC) wing of the Department of Telecommunications, reportedly concluded that Jio’s proposed system meets the required technical standards and is comparable to leading global satellite broadband networks.

India’s Indigenous LEO Satellite Vision

Under the proposal, Reliance Jio plans to deploy between 1,600 and 1,650 satellites in Low Earth Orbit at an altitude of around 650 kilometres.

The planned constellation is expected to provide high-speed satellite connectivity across India, with approximately 32 satellites visible from any location at a given time. The company aims to roll out the network within the next two to three years, subject to regulatory approvals.

According to industry estimates, the satellite system could deliver 4.5 to 5 terabits per second (Tbps) of total data capacity, making it one of the largest satellite broadband projects proposed in India.

The project is expected to require an investment of $10–15 billion (approximately ₹95,000 crore to ₹1.42 lakh crore), reflecting the scale of infrastructure needed for satellite manufacturing, launches, ground stations, and user terminals.

Regulatory Process Moves Forward

Following the successful technical review, the proposal is expected to move into the next phase of regulatory approvals.

The government may now assist Jio in securing orbital slots, coordinating spectrum usage, and filing applications with the International Telecommunication Union (ITU), the global body responsible for managing satellite orbit and frequency allocations.

Obtaining orbital rights remains a critical step, as Low Earth Orbit has become increasingly competitive due to the growing number of satellite broadband projects being planned worldwide.

Officials also indicated that the proposed satellite architecture has been designed to coexist with future Indian LEO constellations, allowing multiple domestic operators to share orbital resources efficiently.

Broadband, Mobile Connectivity, and Strategic Applications

Jio plans to use the satellite network to provide a range of communication services, including satellite broadband, mobile backhaul, enterprise connectivity, and direct-to-device (D2D) satellite communication, particularly in remote and underserved regions where conventional telecom infrastructure is limited.

The company also intends to establish 20 to 22 ground stations across India to support network operations.

Apart from commercial telecommunications, officials have highlighted the project’s potential strategic importance. A domestically developed satellite constellation could strengthen India’s communication infrastructure, reduce dependence on foreign satellite operators, and support national security requirements.

Reports suggest preliminary discussions are underway regarding the possibility of integrating defence-related payloads into some satellites, enabling both civilian and strategic use.

Major Step for India’s Space and Telecom Sectors

Industry analysts view the technical clearance as an important milestone in India’s expanding private space ecosystem. If Jio secures the remaining regulatory approvals and international orbital clearances, the project could become the country’s first large-scale indigenous LEO satellite broadband network.

The initiative also aligns with India’s broader efforts to expand digital connectivity while strengthening its presence in the global satellite communications market.
