Space-Based Surveillance: The New Frontier of Indian Ocean Security

The Indian Ocean is undergoing a strategic transformation as maritime power shifts from traditional fleet size and choke-point control to the integration of space-based assets. As major powers and littoral states increasingly rely on satellite-enabled connectivity for real-time surveillance and threat detection, space has become a critical operational domain. This technological evolution is reshaping regional security, creating new asymmetries between states that possess indigenous satellite capabilities and those that remain dependent on external data providers.

India’s Integration of Space and Maritime Strategy

India has emerged as the most advanced integrator of space-based surveillance in South Asia, spurred by the 2008 Mumbai terror attacks, which highlighted significant gaps in coastal security. India’s strategic approach now treats space as an operational framework alongside land, sea, air, and cyber domains, as codified in the Maritime Doctrine 2025.

The Indian Navy’s reliance on space assets began in earnest with the 2009 launch of the Radar Imaging Satellite-2 (RISAT-2). This was followed by the deployment of GSAT-7, a dedicated military communication satellite that provides secure, resilient connectivity for warships, submarines, and aircraft. In November 2025, India expanded this network with the launch of GSAT-7R. Furthermore, the Information Fusion Center-Indian Ocean Region (IFC-IOR), established in 2018, serves as a central hub for integrating space-based automatic identification systems with coastal radar networks to provide a comprehensive maritime picture.

China’s Orbital Footprint in the Indian Ocean

China is simultaneously expanding its orbital presence to support its maritime activities across the Indian Ocean. Beijing utilizes a multi-layered satellite network to enhance its maritime domain awareness and command-and-control capabilities. The Yaogan reconnaissance satellite series provides high-resolution, all-weather imagery, while the Gaofen constellation supports persistent monitoring of maritime spaces.

Beyond imaging, China has achieved global coverage with its BeiDou navigation system. Unlike traditional GPS, BeiDou features inter-satellite communication and is designed to resist jamming, making it a robust tool for military navigation. Regional integration is also occurring; countries such as Pakistan have begun incorporating BeiDou into their military systems. This creates a strategic dependency where regional actors become embedded within Chinese technological and intelligence networks, extending China’s influence from physical naval deployments to a constant overhead presence.

Structural Constraints for Littoral States

For many South Asian littoral states, the transition to space-based security remains hindered by significant resource and technological gaps. Nations like Sri Lanka and the Maldives occupy vital positions along major sea lines of communication but lack sovereign satellite infrastructure.

* Sri Lanka: While the country has launched small research satellites—including Raavana-1 and the BIRDS-X Dragonfly—these lack the capacity for operational maritime surveillance. The government is currently working toward a National Space Policy to formalize its security outlook.
* The Maldives: With a maritime zone exceeding 900,000 square kilometers, the Maldives faces a massive surveillance challenge. The Maldivian Space Research Organization (MSRO), established in 2022, is seeking to develop a domestic ecosystem, but the nation currently relies on commercial software like SeaVision for maritime domain awareness.

Risks of the Emerging Space Divide

The disparity in space capabilities introduces significant risks to regional stability. As noted by security analysts, reliance on external data providers can lead to “data latency” and uneven situational awareness. A state lacking independent verification capabilities is vulnerable to grey-zone threats, such as the activities of foreign research vessels that may conduct mapping for both civilian and military purposes.

Furthermore, the concentration of surveillance infrastructure in the hands of major powers allows for the potential manipulation of data flow. Similar to the operational constraints seen in other global conflicts, where access to satellite services like Starlink was modulated during active hostilities, South Asian states face the risk that external partners could prioritize or withhold data based on shifting political or commercial interests.

Future Outlook for Regional Maritime Security

To mitigate the risks of overdependence, regional actors are exploring collaborative frameworks. Minilateral initiatives, such as the Colombo Security Conclave and the Indian Ocean Rim Association, provide platforms for sharing maritime data and coordinating surveillance efforts. By pooling resources and diversifying external partnerships, littoral states aim to preserve their strategic autonomy. Ultimately, the security of the Indian Ocean will increasingly depend on the ability of nations to monitor, interpret, and act upon information in real time, moving beyond the traditional focus on naval hardware toward a sophisticated, space-integrated maritime architecture.
