India’s First Education Satellite: EDUSAT
The Indian Space Research Organisation (ISRO) launched GSAT-3—better known as EDUSAT—on 20 September 2004. This was India’s first satellite specifically designed for educational purposes. Its main goal was to deliver interactive and satellite-based education to even the most remote areas of the country.
EDUSAT opened new pathways for delivering digital content directly to classrooms in schools and colleges. Teachers and students could connect interactively, sharing video lectures, training programs, and educational materials easily. Through EDUSAT, teacher training, curriculum-based education, and interactive classroom sessions became possible nationwide. Students in remote schools and rural regions gained access to high-quality education, bringing about a revolution in technological innovation and equal opportunity in learning.
