ISRO Chairman V Narayanan was the Chief Guest at the 35th Convocation Ceremony at the Birla Institute of Technology, Mesra, close to Ranchi last week. During his speech, V Narayanan explained the role of ISRO satellites during operation Sindoor, saying "Today we are working on multiple areas. One of the responsibilities is ensuring the safety and security of this country in whatever way possible. During Sindoor Operation, our satellites perfectly worked and contributed to ensure safety of Indians. Today, we are having 56 satellites in orbit, working very well, and we have to increase this number by at least three times in three years timeframe. We are working towards that."
For surveillance and reconnaissance purposes, ISRO uses a combination of dedicated military satellites as well as dual-use satellites such as the HysIS hyperspectral satellite primarily used for monitoring crops, biomass and coastal regions, the CartoSat series of satellites for remote sensing and mapping, as well as the RISAT all-weather radar imaging satellite used for agriculture and disaster management. These assets support precision campaigns such as Operation Sindoor, along with internationally procured commercial imagery. ISRO plans to deploy 52 satellites in 2026 in collaboration with private companies towards bolstering India's space Intelligence, Surveillance, and Reconnaissance (ISR) capabilities.
At the DefSpace Symposium in April, CDS General Anil Chauhan had said, "Private sector must continue to innovate in cutting edge space technologies. Collaboration between private companies, armed forces, and DRDO in space is essential for developing a very resilient and self-sufficient space defence infrastructure." The deployment of 52 satellites is covered under the Space-based Surveillance 3 scheme, where ISRO is building about 21 satellites, with the remaining 31 being sourced from private industries. While the spatial resolution of our domestic satellites is comparable to that of international providers, the temporal resolution is not, which is a capability gap that India needs to bridge.
