Introduction
India’s private space sector has achieved a historic milestone with the successful launch of Mission Drishti, developed by Bengaluru-based space-tech startup GalaxEye. The satellite was launched aboard the powerful Falcon 9 rocket from California, marking a major advancement in India’s Earth Observation (EO) capabilities.
Mission Drishti is being hailed as the world’s first OptoSAR satellite, integrating Electro-Optical (EO) and Synthetic Aperture Radar (SAR) technologies into a single platform. This breakthrough innovation places India among the leading nations in advanced satellite imaging and remote sensing technology.
What is Mission Drishti?
Mission Drishti is an advanced Earth Observation satellite designed to provide high-resolution imagery under all weather conditions, during both day and night.
Unlike conventional satellites that rely only on optical imaging, Mission Drishti combines:
- Electro-Optical (EO) Sensors
- Synthetic Aperture Radar (SAR) Sensors
This unique fusion enables the satellite to deliver uninterrupted and highly accurate geospatial intelligence.
The satellite weighs approximately 190 kilograms and offers a 1.5-meter spatial resolution, making it one of India’s most advanced privately developed satellites.
Understanding OptoSAR Technology
Electro-Optical (EO) Imaging

Synthetic Aperture Radar (SAR)
SAR technology uses radar pulses instead of sunlight to capture images.
Key advantages include:
- Imaging through clouds and rain
- Night-time monitoring capability
- High reliability in adverse weather
- Accurate terrain and object detection
SAR is widely used for:
- Defence surveillance
- Maritime monitoring
- Disaster response
- Strategic reconnaissance
Why Mission Drishti is Revolutionary
Mission Drishti integrates EO and SAR technologies into a single satellite platform, creating the world’s first OptoSAR system.
This means:
- Better image accuracy
- Continuous monitoring
- Reduced data gaps
- Faster intelligence gathering
- Improved Earth observation capabilities
The integration significantly enhances the efficiency of remote sensing operations.
