EDUSAT Satellite Uses in Education Full Form, Role, Advantages, Disadvantages 

EDUSAT, also referred to as GSAT-3, was designed to facilitate distance education, spanning from school-level to higher education.

It marks the pioneering initiative of being the first dedicated "Educational Satellite," offering the nation satellite-based two-way communication to classrooms for the delivery of educational materials.

What does EDUSAT mean? Who launched EDUSAT?

GSAT-3, alternatively recognized as EDUSAT, was a communications satellite. This was a “Geosynchronous satellite” developed on I-2K bus. GSAT-3 was co-located with METSAT(KALPANA-1) and INSAT-3C at 74o E longitude.

GSAT-3 satellite launched by India and deployed by the Indian Space Research Organisation on September 20, 2004 from the Launch site : SHAR, Sriharikota, India

It holds the distinction of being India's inaugural satellite purposefully crafted to cater solely to the educational domain.

EDUSAT Full Form

EDUSAT, an acronym for Education Satellite, was launched by the Indian Space Research Organisation (ISRO) on September 20, 2004. It was designed to cater specifically to the educational sector, marking a significant milestone in the integration of satellite technology with learning.

What is the Role of EDUSAT in Education? 

The primary role of EDUSAT is to facilitate distance education and enhance the reach of educational resources to remote and underserved areas. 

By transmitting interactive educational content, including lectures, tutorials, and multimedia material, EDUSAT aims to democratize access to quality education regardless of geographical constraints.

What are the Advantages and Disadvantages of EDUSAT in education?


  1. Widespread Accessibility: EDUSAT extends the reach of education to rural and remote areas, where conventional infrastructure is lacking.
  2. Interactive Learning: Through two-way communication channels, students can actively engage with educators, fostering a conducive learning environment.
  3. Cost-Effectiveness: Compared to establishing physical infrastructure, satellite-based education proves to be a more economical option in the long run.


  1. Technological Dependency: Reliance on satellite technology makes EDUSAT susceptible to disruptions due to weather conditions or technical failures.
  2. Limited Interactivity: Despite enabling two-way communication, the interactive nature of satellite-based learning may not fully replicate traditional classroom experiences.
  3. Infrastructure Challenges: Ensuring access to receiving equipment and maintaining ground infrastructure poses logistical challenges, especially in remote regions.

Edusat Satellite Uses

  1. Distance Education: EDUSAT facilitates the delivery of educational content to learners located far from conventional educational institutions.
  2. Teacher Training: It supports professional development programs for educators, enhancing their pedagogical skills and subject knowledge.
  3. Telemedicine: In addition to education, EDUSAT also supports telemedicine services, enabling remote healthcare delivery in underserved areas.

Is EDUSAT still working?

Until September 2010, the EDUSAT satellite actively served various initiatives led by the Indian Space Research Organisation (ISRO), including telemedicine, tele education, and village resource centers (VRC) projects. Following the decommissioning of EDUSAT, the responsibilities and networks were seamlessly transitioned to INSAT-4CR and other relevant extensions.
