The Ariane Passenger Payload Experiment (APPLE), was an experimental communication satellite launched by the Indian Space Research Organisation on June 19, 1981, by Ariane, a launch vehicle of the European Space Agency (ESA) from Centre Spatial Guyanais near Kourou in French Guiana.
APPLE was India's first experimental geostationary communication satellite. It was used in several communication experiments including relay of TV programmes and radio networking. It went out of service on September 19, 1983.
INSAT-1A
INSAT-1A was an Indian communications satellite which formed part of the Indian National Satellite System. It was launched in 1982 for a period of seven years. Following a series of failures, the satellite was abandoned in September 1983. It was the first operational multipurpose communication satellite.
INSAT-1B
INSAT-1B was an Indian communications satellite which formed part of the Indian National Satellite System. It was launched in 1983 for seven years. At the end of its seven-year design life, it was replaced by the newly launched INSAT-1D. In 1992, it was relocated before being decommissioned in August 1993.

GSAT-3, also known as EDUSAT, was a communications satellite which was launched on 20 September 2004 by the Indian Space Research Organisation. EDUSAT 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.
EDUSAT was successfully launched into from the Satish Dhawan Space Centre in Sriharikota. India's first broadband network on EDUSAT for schools - ViCTERS (Versatile ICT Enabled Resource for Students) was inaugurated by Dr. A.P.J Abdul Kalam, on 28 July 2005 in Thiruvananthapuram. It has revolutionized classrooms through an interactive IP-based technology called ‘[email protected] Project’. Kerala has since demonstrated how EDUSAT could be used to successfully empower teachers.
It was decommissioned in September 2010 and relocated to a graveyard orbit.
