India is accelerating the development of its ambitious ₹27,000-crore Space-Based Surveillance (SBS-III) programme, a strategic initiative that will deploy a constellation of 52 surveillance satellites to strengthen national security and real-time monitoring capabilities. The project is designed to enhance coverage of India’s borders, maritime zones and the Indian Ocean region.
The programme was approved in 2024 and is expected to be rolled out in phases through 2029. Reports indicate that 31 of the 52 satellites will be built by private-sector companies, reflecting the growing role of India’s commercial space industry in national security projects.
Among the companies being closely watched are Astra Microwave Products, Data Patterns and Bharat Electronics Limited. These firms already have strong links with India’s defence and space ecosystem and are considered potential beneficiaries of future orders related to satellite systems, radar payloads, communications equipment and surveillance technologies.
The satellite network will significantly expand India’s intelligence, surveillance and reconnaissance capabilities. It is expected to provide faster detection of military activity, maritime movements and potential security threats while improving coordination across defence agencies.
Industry experts view SBS-III as one of India’s most important space-defence programmes to date. Beyond strengthening national security, the project is expected to create major opportunities for domestic aerospace, electronics and satellite manufacturing companies as India deepens private participation in the space sector.
