Mission Drishti - India’s largest privately developed Earth observation satellite - was launched on 3^rd May 2026 by Bengaluru-based GalaxEye. It is the world's first OptoSAR satellite. It integrates Electro-Optical (EO) and Synthetic Aperture Radar (SAR) sensors for 24/7, all-weather imaging.

In this context, it is important to understand Opto-SAR’s key advantages over conventional SAR. Some salient points are outlined below.

Technological Superiority

• Opto-SAR utilises photonic technologies to bypass traditional electronic bandwidth limits, delivering significantly higher spatial resolution.
• Unlike conventional systems, it is immune to electromagnetic interference, ensuring clearer imagery in diverse environmental conditions.

Enhanced Efficiency & Reliability

• Optical signal processing enables parallel data handling, overcoming the processing bottlenecks typical of standard SAR.
• Additionally, compact photonic components optimize Size, Weight, and Power (SWaP) efficiency, making it ideal for satellite and UAV deployment.

Summing Up

By merging electro-optical (EO) and radar capabilities, Mission Drishti provides a reliable, high-fidelity observation solution that overcomes the inherent limitations of conventional SAR platforms.
