Reliance Jio is laying the groundwork for an ambitious venture into space, with plans to deploy a low Earth orbit (LEO) satellite constellation valued at an estimated $10-15 billion. This project, expected to be executed over the next two to three years, aims to establish India's first large-scale domestic satellite communication network, directly challenging global players like Elon Musk's Starlink, Amazon Leo, and Eutelsat OneWeb.
India's Push for Digital Sovereignty
The proposed constellation, comprising between 1,600 and 1,650 satellites positioned at approximately 650 km altitude, is designed to deliver both space-based broadband and direct-to-device connectivity across India. Beyond commercial competition, Jio's initiative addresses a critical national push for digital sovereignty. Geopolitical tensions and conflicts have underscored the strategic vulnerabilities inherent in relying on foreign space networks for critical communication infrastructure.
Security Concerns Over Foreign Satellite Networks
A key aspect of India's approach involves strict security apprehensions, particularly regarding foreign satellite infrastructure and data routing. The Indian government has expressed caution about granting security approvals to Starlink, primarily due to its Laser Inter-Satellite Link (LISL) technology. This technology allows newer-generation Starlink satellites to beam data directly to one another in space, forming a mesh network that could potentially route Indian data outside national borders.
Sources indicate that the ability of companies like SpaceX to remotely manipulate connectivity, as seen during conflicts in Ukraine and West Asia where coverage was geofenced, raises significant security flags for Indian authorities.
Ensuring Data Stays Local
To mitigate these risks, Indian authorities are planning robust safeguards. Any data packet originating from an Indian terminal using a satellite service will likely be mandated to downlink to an Indian gateway. For Starlink's LISL-enabled satellites, these laser links may be disabled or heavily restricted for traffic involving Indian users to ensure data remains within national jurisdiction.
In contrast, competing services planning Indian operations, such as Eutelsat OneWeb and the Jio-SES satellite joint venture, do not utilize LISL technology, which may simplify their security clearance process. Currently, all three major players—Starlink, Eutelsat OneWeb, and Jio-SES—are still awaiting full security clearances to officially commence services in India, as Jio's own project remains under evaluation by the Indian National Space Promotion and Authorisation Centre (IN-SPACe).
