Hello Dear Reader,
Today I have given an idea about how our country started
Satellite-based Education and Training development in 1975-76.
Satellite Instructional Television Experiment (SITE):
The journey of societal
development by ISRO in view of the available TV & Satellite technologies,
started with Satellite Instructional Television Experiment (SITE), which was
hailed as the largest satellite-based sociological experiment in India during
1975-76. The SITE was the first pioneering effort to provide a system test of direct
broadcast technology in India and use satellite television as a medium of
education and developmental training program. Under this giant experiment, the
TV programs were transmitted from Ahmedabad and Delhi Earth Station via the
'Application Technology Satellite' (ATS-6) covering 200,000 people across 2400
villages scattered in the isolated villages of 20 districts in the cover six
states (Rajsthan, Bihar, Orissa, Madhya Pradesh, Karnataka, and Andhra Pradesh)
of India.
SITE beamed programs
in the fields of health, family planning, adult literacy, agriculture, school
education, and teacher training. The primary target audience consisted of women,
farmers, school children, and primary school teachers. The credit of training
50,000 science teachers primary schools in one year goes to SITE.
SITE demonstrated to
space scientists, educationists, sociologists and media experts the impact of
satellite television in social development and how it can make teaching and
training, a whole new experience.
Kheda Communications Project (KCP):
The
need for wider coverage and local programs conceived the idea of “limited re-broadcast” and de-centralization of
the television broadcasting concept of SITE giving new birth to the ‘Kheda
Communication Project’, as one of the major outcomes of SITE (initiated as
part of SITE in 1976).
Training and Development
Communication Channel (TDCC) and Tele-Education (TE):

As
shown in fig.1 a total of 8 extended C-band (frequency range 6-8GHz) 6 channels
on INSAT-3B and 2 on Edusat are being
used for TDCC service that has been operational since 1995, it provides ‘1-way
video & 2-way audio’.
As
shown in fig.1 teaching-end include a studio and uplink facility for
transmitting live or pre-recorded lectures. The participants at the classrooms
located nationwide, receive lectures through simple dish antennas with a different diameter as per the requirement (DRS – Direct Reception Sets) and
have the facility to interact with lecture using telephone lines. Thus main
objective of TDCC was to impact training through the “Interactive Training
Programmes (ITPs)”. The teaching-end are available at Gujarat, Madhya-Pradesh,
Orissa, Karnataka, and Goa. Several state government & universities are
using TDCC system extensively for Distance Education, Rural Development,
Training Development Broadcasting, etc.
TDCC
has proven to be cost-effective tools in promoting various developmental
activities like distance education, rural development, health, and nutrition,
sanitation, women and child development benefitting over 60,000 participants
including primary school teachers and panchayat members of various states.

Along
with TDCC for the requirement of distance education ISRO launch India’s first
satellite dedicated to education the ‘Edusat’ in the year 2004. The GSAT-3
(Edusat), lauched by GSLV-F01 in September 2004. In India’s first thematic
satellite dedicated exclusively for educational services, hence it names ‘Edusat’. Edusat implemented all the latest techniques like audio-video visualization,
multi-centric system, etc..
