TDB-DST signs ₹63.84 crore RDI Fund agreement with GalaxEye for multisensor OptoSAR satellite
On 24 September 2026 the Technology Development Board of DST signed an agreement with Bengaluru-based GalaxEye Space Solutions for ₹63.84 crore support under the RDI Fund to develop a next-generation multisensor satellite.
Summary
The project has a total approved cost of ₹247.69 crore. The indigenous OptoSAR technology combines Synthetic Aperture Radar (SAR) and optical imaging. Optical imaging gives detailed pictures but is limited by clouds and light, while SAR works day and night and through cloud cover; fusing the two aims to give a more continuous picture of the Earth.
