Mission Drishti

Recently, Bengaluru-based space start-up GalaxEye successfully launched its Mission Drishti satellite aboard the Falcon 9 launch vehicle from California, USA. The mission marks a major milestone for India's private space sector and demonstrates the growing capabilities of indigenous space technology startups.

About Mission Drishti

Mission Drishti is a pioneering Earth Observation (EO) satellite developed by GalaxEye. It is regarded as the world’s first multi-sensor Earth observation satellite and represents a significant technological advancement in the field of remote sensing.

The satellite is also recognized as India’s largest privately built satellite and the highest-resolution satellite developed by the country's private sector. It has been designed to provide highly accurate and continuous Earth observation data for a variety of civilian and strategic applications.

World’s First OptoSAR Satellite

The most distinctive feature of Mission Drishti is that it is the world’s first OptoSAR satellite. The term OptoSAR refers to the integration of Electro-Optical (EO) sensors and Synthetic Aperture Radar (SAR) sensors on a single satellite platform.

This combination enables the satellite to overcome the limitations of traditional Earth observation systems and ensures uninterrupted data collection under diverse environmental conditions.

Electro-Optical (EO) Sensors

Electro-optical sensors capture high-resolution images using reflected sunlight. These sensors provide detailed visual information and are highly effective during daylight hours and in clear weather conditions.

Synthetic Aperture Radar (SAR) Sensors

Synthetic Aperture Radar uses radar waves to image the Earth's surface. Unlike optical systems, SAR can operate day and night and can penetrate clouds, smoke, fog, and adverse weather conditions. This capability makes SAR particularly valuable for monitoring regions where optical imagery may be unavailable.

By integrating both EO and SAR technologies, Mission Drishti can provide continuous, high-quality imagery regardless of weather or lighting conditions.

Technical Features

Mission Drishti has been engineered as an advanced remote-sensing Earth observation system capable of generating highly accurate geospatial information.

The satellite weighs approximately 190 kilograms and offers an impressive spatial resolution of 1.5 metres, allowing it to capture detailed images of the Earth's surface. It is optimized for spatial, spectral, and temporal resolution, ensuring precise and frequent observations.

These capabilities make it suitable for applications requiring high levels of accuracy and reliability.

Applications of Mission Drishti

The satellite is expected to serve a broad range of users, including governments, defence agencies, research institutions, and private industries.

One of its major applications is border surveillance, where continuous monitoring is essential for national security. The satellite can also support defence operations by providing timely intelligence and situational awareness.

In the field of disaster management, Mission Drishti can help monitor floods, cyclones, landslides, and forest fires, enabling quicker response and relief operations.

The satellite will also play an important role in infrastructure monitoring, allowing authorities to track roads, railways, urban development projects, and critical assets.

In the agricultural sector, it can assist in crop monitoring, yield estimation, and precision farming, while in the financial and insurance sectors it can support risk assessment, damage evaluation, and claim verification.

Significance for India’s Space Sector

Mission Drishti highlights the rapid growth of India's private space ecosystem following reforms that encouraged greater private participation in space activities. The mission demonstrates the ability of Indian start-ups to develop cutting-edge technologies that can compete globally.

The success of GalaxEye also aligns with India's broader objective of becoming a leading player in the global space economy and promoting innovation-driven growth in the space sector.

Conclusion

Mission Drishti represents a landmark achievement in Earth observation technology. As the world's first OptoSAR satellite, it combines the strengths of electro-optical and radar imaging to provide continuous, high-resolution Earth observation data. Its applications in defence, border security, disaster management, infrastructure monitoring, agriculture, and financial services make it a strategically important asset for India and a significant milestone for the country's private space industry.
