Drishti is an Earth observation satellite from the Indian start-up GalaxEye that carries a radar and an optical camera on one platform. A SpaceX Falcon 9 launched it from Vandenberg, California, on 3 May 2026.
GalaxEye calls its payload OptoSAR: an X-band synthetic aperture radar and a seven-band multispectral camera that look at the same place in the same pass. Radar works through cloud and at night; the camera gives images people can read easily. Combining them gives aligned data for farming, infrastructure, disasters and ships at sea.
The radar uses VV polarisation and two modes, Stripmap and Spotlight, reaching 0.9 m resolution in Spotlight. The multispectral imager, with bands including coastal blue, red edge and near-infrared, sees 3.6 m detail. Fused products are delivered at 1.8 m. The radar swath is 30 km and the optical swath 10 km. The satellite weighs about 190 kg, and GalaxEye says it is the largest satellite built privately in India.
