As the SpaceX Falcon 9 roared off the pad at Vandenberg Space Force Base, California, it carried more than just hardware into orbit. It carried the five year long dream of a group of IIT Madras alumni who dared to ask: Why can’t we see through the clouds? With the successful deployment of Mission Drishti, Bengaluru based startup GalaxEye Space has officially launched the world’s first OptoSAR satellite, marking a revolutionary shift in how humanity observes the planet.
The OptoSAR Breakthrough: Seeing the Unseen
For decades, Earth observation was a game of compromises. You could have clear, intuitive optical photos that looked like real life, but they were useless at night or on cloudy days. Alternatively, you could use Synthetic Aperture Radar, or SAR, to see through weather and darkness, but the resulting data was often grainy and difficult for non experts to interpret.
Mission Drishti changes the arithmetic of the sky. By housing both a high resolution SAR sensor and a 7 band multispectral optical imager on a single 190 kg platform, GalaxEye has achieved what they call SyncFusion. This technology allows the satellite to capture the same location with both sensors simultaneously. The result is analysis ready data that combines the all weather reliability of radar with the intuitive clarity of a high definition photograph. It is, quite literally, an eye that never blinks and never sleeps.
A Human Story: From IIT Madras to the Stars
While the technology is cold and clinical, the journey behind it is deeply human. Founded in 2021 by Suyash Singh, Denil Chawda, and Satya Chakravarthy, GalaxEye was born in the research labs of IIT Madras. The team spent over five years in a cycle of building, testing, and iterating, as CEO Suyash Singh noted.
The launch represents a moment of profound national pride. Prime Minister Narendra Modi hailed the mission on social media, describing it as a testament to the passion for innovation of Indian youth. For the 100 plus engineers at GalaxEye, this was not just a technical delivery. It was the culmination of a mission to prove that an Indian private company could build the largest and most advanced Earth observation satellite in the history of the nation.
Budget, Funding, and the Global Space Race
Innovation on this scale requires significant capital. GalaxEye has raised approximately 18.8 million dollars, or roughly 155 crore rupees, to date. This includes a landmark 14.5 million dollar Series A round completed just months before launch. While global giants like Finland’s ICEYE or the US based Capella Space have raised hundreds of millions of dollars, the lean and mean approach of GalaxEye has allowed them to beat these incumbents to the punch with a multi sensor fused platform.
Unlike competitors who often operate separate constellations for radar and optical data, requiring complex post processing to align the images, the single platform approach of GalaxEye eliminates alignment errors. This makes their data decision grade, which is a vital requirement for high stakes industries like insurance, precision agriculture, and national defense.
The Drishti Constellation
Mission Drishti is only the beginning. GalaxEye plans to launch a constellation of ten satellites over the next 2.5 years. This network will provide a revisit frequency of just a few hours, allowing users to monitor changes on the ground in near real time.
Equipped with electric propulsion for a longer life and an NVIDIA Jetson Orin AI processor for on board data crunching, the Drishti satellites are designed to be utilities rather than just experiments. As the satellite begins its commissioning phase in orbit, the global space community is watching closely. India has not just joined the private space race. With Mission Drishti, it has taken the lead in the next generation of Earth intelligence.
