GSAT-3, also known as EDUSAT, was a communications satellite which was launched on 20 September 2004 by the Indian Space Research Organisation.

It is mainly intended to meet the demand for an interactive satellite-based distance education system for the country.

The deployment of the arrays as well as the general health of the satellite were monitored by the ground station of the ISRO Telemetry, Tracking and Command network (ISTRAC) located in the Indonesian island of Biak.

Ground stations at Lake Cowichan (Canada), Fucino (Italy) and Beijing (China) are supporting MCF in monitoring the health of the satellite and its orbit raising operations.

Master Control Facility (ISRO) at Hassan is responsible for all post launch operations of the satellite.
