EDUSAT or GSAT-3, launched on 20th September 2004 by the Indian Space Research Organisation (ISRO), is the first Indian satellite built exclusively to serve the educational sector. It is mainly intended to meet the demand for an interactive satellite-based distance education system for the country.

It has revolutionized classroom teaching through IP based technology. EDUSAT has five KU band transponders providing spot beams, one KU beam transponder providing national beam and six extended C-band transponders providing national coverage beams.

EMRC Roorkee’s virtual classroom, through its satellite interactive terminal(SIT) of EDUSAT, is part of the UGC-CEC EDUSAT network. During live sessions, lectures of eminent Subject Experts from various fields are delivered from the teaching end i.e. CEC studios or any Media Centre studios, after which the students, present at the SIT or classroom end, interact with the experts live i.e. through audio-video conferencing, text mode or through telephones. Thus students can benefit from experts located in various educational institutions across the country.

At present, there are over hundred such Satellite Interactive Terminals (SITs) and Receive only Terminals (RoTs) under the CEC EDUSAT network, installed at various colleges, Academic Staff Colleges and Universities across the country. Many more are being added with the purpose of providing quality higher education to the remote areas through satellite network.

The lectures delivered through EDUSAT are also recorded and are available on
