GalaxEye to Develop Indigenous OptoSAR Earth-Observation Satellite
On 24th September 2026, the Technology Development Board (TDB) under the Department of Science & Technology (DST) signed an agreement with GalaxEye Space Solutions to support development of an indigenous multisensor satellite using OptoSAR technology, which combines optical and radar imaging for high-resolution Earth observation.
What is OptoSAR?
OptoSAR integrates two complementary remote-sensing technologies:
- Electro-Optical (EO) Imaging: Produces detailed visual imagery but depends on adequate illumination and can be obstructed by clouds.
- Synthetic Aperture Radar (SAR): Uses microwave signals to image the Earth and can operate day or night and through cloud cover.
- By fusing data from both sensors, OptoSAR aims to provide ....
