Conclusion
Introduction - EDUSAT Government of India launched the Educational
Satellite (EDUSAT) in September 2004, which is expected to revolutionize the Distance Education Programmes in the country.
GSAT-3, known as EDUSAT is meant for distant class room education from school level to higher education.
This is the FIRST dedicated "Educational Satellite" that provide the country with satellite based two way communication to class room for delivering educational materials.
This is a Geo-synchronous satellite developed on I-2K bus.
Implementation - EDUSAT
Karnataka, Kerala, Madhya Pradesh and Maharashtra are the four States where EDUSAT programme are implemented in the current year.
In each of these States a particular target and area has been identified for utilization of EDUSAT.
Different agencies have been identified with the responsibility for the development of Software, Teacher Training, Monitoring & Evaluation and overall implementation of the project.
Indian Space Research Organization (ISRO), Serva Siksha Abhiyan (SSA) are also involved in the implementation the Programme.

Practical Use - EDUSAT
Important Note to be Discussed ….
As we have discussed, there are many applications of EDUSAT in the practical manner. This is the Best way in terms of Distance Education.
So, I have noticed some points as the as the advantages & drawbacks of this system, as following below :
Advantages are :
1.Its Flexible 2.Saves Time & Energy3.Study at your own pace4.Saves Money5.More convenient than classroom study6.24*7 access to study material & fellow students7.Study any topic you want to study.
Drawbacks are : 1.Time and frustration involved learning how to get on-line for novices.2.Occasional internet provider downtime .3. Student must be more active and self-directed in learning environment -Depends on individual motivation and initiative .4. Demands large effort and cost to develop appropriate materials .5. Demands large effort to create and maintain the technological infrastructure .6. Distance Education is not for everyone.- It is not for undisciplined learners nor inflexible instructors.
My Conclusion
The launch of EDUSAT has helped in providing quality instruction through video programmes to students studying in the interior villages. The students have benefited from the video programmes delivered through the Satellite.
The benefit gained is in terms of gain in knowledge and understanding of the content, improvement in attendance and holding attention and interest in viewing programmes. The teacher involvement during the broadcast as facilitator and conduct of Pre and Post broadcast activity is note worthy.
