GalaxEye, a Bengaluru-based company, has made a significant breakthrough in Earth observation technology by unveiling its OptoSAR technology at the BRICS 2026 programme. This innovative technology combines optical and Synthetic Aperture Radar (SAR) data on a single platform, offering all-weather, day-and-night capabilities for defence, surveillance, and disaster management applications.
The OptoSAR concept marries a SAR sensor with optical/multispectral imaging, leveraging the strengths of both data sources. While optical imagery is a familiar information source, it often struggles with cloud cover and darkness. SAR, on the other hand, can peer through clouds and take snapshots of the Earth's surface by day and night. By putting an X-band SAR sensor and a seven-band multispectral imager on the same satellite platform, GalaxEye's technology allows both to obtain data during the same pass.
The Mission Drishti satellite, launched on 3 May 2026, is carrying the OptoSAR payload and is expected to offer all-weather, day-and-night Earth observation capabilities. The satellite has a fused spatial resolution of up to 1.2 metres, depending on the imaging product. This combination of optical and SAR data can benefit a range of domains, from defence and maritime surveillance to infrastructure monitoring, agriculture, and disaster management.

Explore Carbon Fiber →For defence users, the ability to get SAR images through clouds combined with optical data to help interpret the image would be valuable. Collecting the data sets at the same time would avoid the complications of trying to fuse images from different satellites that may have imaged a given area at different times and from different perspectives.
GalaxEye's participation at BRICS 2026 also points to the growing role of India's private space industry in developing dual-use Earth observation technologies. This trend is expected to continue, with private companies like GalaxEye playing a significant role in shaping the future of Earth observation.
The OptoSAR technology has the potential to revolutionize the field of Earth observation, offering a more comprehensive and accurate understanding of the Earth's surface. With its ability to provide all-weather, day-and-night capabilities, OptoSAR is poised to become a game-changer in the field of defence, surveillance, and disaster management.
In conclusion, GalaxEye's OptoSAR technology is a significant breakthrough in Earth observation, offering a new paradigm for defence, surveillance, and disaster management applications. Its potential to revolutionize the field of Earth observation is vast, and its impact is expected to be felt for years to come.
