Full Form of EOK
What is EOK?
Earth Observation Khagol (EOK) is a specialised Indian Space Research Organisation (ISRO) programme that focuses on deploying small satellites for high-resolution Earth imaging and data collection. The term 'Khagol' derives from the Sanskrit word for 'sky' or 'celestial sphere', reflecting its aim to study terrestrial changes from space. EOK satellites are typically lightweight, cost-effective, and designed to supplement larger Earth observation platforms like the IRS (Indian Remote Sensing) series. These satellites capture multispectral imagery used for agriculture monitoring, urban planning, disaster management, and environmental assessment across India. The programme is part of ISRO's ongoing efforts to democratise space data by offering frequent revisit times and high spatial resolution, making it valuable for both government agencies and private enterprises. EOK missions are launched on ISRO's Polar Satellite Launch Vehicle (PSLV) and have been operational since the early 2020s. For students preparing for competitive exams such as UPSC or GATE, understanding EOK's role in India's space ecosystem is important, as it exemplifies technological frugality and application-driven satellite design. The data from EOK satellites is increasingly used in precision farming and infrastructure development projects, demonstrating a direct impact on national growth.

EOK — frequently asked questions
What is the full form of EOK?
The full form of EOK is Earth Observation Khagol, a satellite programme by ISRO dedicated to small satellite-based Earth imaging.
How is EOK different from other ISRO Earth observation satellites?
EOK satellites are smaller, lighter, and cheaper than traditional remote sensing satellites, allowing for quicker deployment and more frequent revisit times for specific regions.
What are the main applications of EOK data in India?
EOK data is used for crop monitoring, drought assessment, urban sprawl mapping, flood damage evaluation, and environmental compliance monitoring by state and central agencies.
