EDUSAT Programme

EDUSAT, launched by Geosynchronous Satellite Launch Vehicle (GSLV-F01) in September 2004, is India's first thematic satellite dedicated exclusively for educational services. The satellite is specially configured to relay through audio-visual medium, employing multi-media multi-centric system, to create interactive classrooms. EDUSAT has multiple regional beams covering different parts of India - five Ku-band transponders with spot beams covering northern, north-eastern, eastern, southern and western regions of the country, a Ku-band transponder with its footprint covering the Indian mainland region and six C-band transponders with their footprints covering the entire country. EDUSAT is being implemented in three phases, pilot, semi-operational and operational phases. While pilot phase has continued, semi-operational and operational phase have been put into implementation during the year.

EDUSAT is already providing a wide range of educational delivery modes like one-way TV broadcast, interactive TV, video conferencing, computer conferencing, web-based instructions, etc.

Sixty four networks have been setup so far, out of which 10 networks use national Ku-band beam and 36 networks are operational on regional Ku-band and Extended-C band national beams. There are more than 3386 interactive classrooms and 31313 receive only classrooms totaling close to 34699 classrooms. Networks have already been setup in 24 states covering almost entire country including all islands (Andman & Nicobar, Lakshdweep), North-Eastern states and Jammu & Kashmir. Implementation in remaining states is under progress.

Special Networks

One of the innovative networks on EDUSAT is the network for "Blind schools". Blind People's Association, Ahmedabad is a leading organisation promoting education, training, employment and rehabilitation for blind persons. Considering the specific needs of the blind people, an altogether different kind of broadcast network configuration delivering live audio and data which is read by blind person through its printed impression (Braille) was set up.

Another special network in Ext C-band connecting 50 engineering institutes across the country has been established to impart teaching by distinguished professors/faculty from top 21 universities in USA who would visit India to conduct eight-week courses in various subjects in engineering. This network is now shared by IIT-Bombay network with additional 30 end users.

Apart from this, network for IIM, Bangalore connecting with its other centre in Chennai; an extended C-band network connecting all the five centers of National Council of Science Museums for promoting scientific temperament among students and general public; network for Mahabharatha Sansthan for online transmission of digitised manuscripts from remote areas through mobile terminal to centralised center for archival so as to preserve them; two networks in Kerala for imparting education and awareness to parents and teachers of mentally challenged children schools; network in Tamilnadu and Pondicherry connecting centers of Aravind Virtual Academy for providing eye-care; etc. are a few special networks, which have been set up/under implementation under EDUSAT Utilisation Programme.

Educational TV Services

INSAT is being used to provide Educational TV (ETV) service for primary school children in Tamil, Marathi, Oriya, Telugu and Hindi. A general enrichment programme on higher education (college sector) is telecast on the national network. These programmes, provided by the University Grants Commission (UGC), are a part of its countrywide classroom programme. The Indira Gandhi National Open University (IGNOU) broadcasts half an hour curriculum based lectures daily via the national network for the students.

Training and Developmental Communications Channel (TDCC)

A total of 8 Ext. C-band channels - 6 on INSAT-3B and 2 on Edusat - are being used for Training, Development and Communication Channel (TDCC), a service that has been operational since 1995. It provides 1-way video & 2-way audio system of interactive education. The teaching-end includes a studio and an uplink facility for transmitting live or pre-recorded lectures. The participants at the classrooms located nationwide receive lectures through simple dish antennas (DRS) and have facility to interact with lecturers using telephone lines.

Several state governments and universities are using the TDCC system extensively for Distance Education, Rural Development, Women & Child Development, Panchayati Raj, Health, Agriculture, Forestry, etc. The teaching-ends are now available at Gujarat, Madhya Pradesh, Orissa, Karnataka and Goa. The DRS network consists of more than 5000 classrooms spread over the country.
