The primary goal of the program is to promote space education among high school students and to support the qualification and scientific careers of young people, as university students and young researchers. Another target of this program is to develop a small space mission for low cost scientific experiments and technological tests in orbit. The program involves courses and post-doc positions at several national universities. The students are also involved in the development of a small payload sun sensor which will be hosted on board EduSat. The structure is modular and fast to assemble and disassemble, thus permitting a good flexibility even in substituting a complete section whenever it is needed and giving to the students the possibility to work, at the same time, on different subsystems. The solar arrays are surface-mounted and the photovoltaic system is based upon triple junction solar cells GaAs which are glued to a non-conductive support.

It is mainly intended to meet the demand for an interactive satellite based distance education system for the country. Edusat is expected to have a life of seven years in space, during which it will help educational institutions make up for, among other things, the dearth of good teachers by providing connectivity with classrooms far away. The universalisation of education has become the top priority in India, especially for the developing countries.
But the extension of quality education to remote and rural regions becomes a Herculean task for a large country like India with multi-lingual and multi-cultural population separated by vast geographical distances.
There is a lack of adequate rural educational infrastructure and non-availability of good teachers in sufficient numbers which adversely affect the efforts made in education.
The spacecraft is built around a standardised spacecraft bus called I-2K. It has a multiple spot beam antenna with 1. Satellites can establish connectivity between urban educational institutions and a large number of rural and semi-urban educational institutions to provide an educational infrastructure. Besides supporting formal education, a satellite system can facilitate the dissemination of knowledge to the rural and remote population about important aspects like health, hygiene and personality development and allow professionals to update their knowledge base as well.
Thus, in spite of limited trained and skilled teachers, the aspirations of the growing student population at all levels can be met through the concept of tele-education. During this experiment, programmes pertaining to health, hygiene and family planning were telecast directly to about 2, Indian villages spread over six states. Later, with the commissioning of INSAT system in , a variety of educational programmes began telecast.
