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: 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.EQUIPMENT USED: EQUIPMENT USED Various Equipment's Antenna Modem LAN Screen C amera Client PC ** Many other devices can be used.Devices & Protocol Used: Devices & Protocol Used PROTOCOL USED :- IP ADDRESS (Because of the use of LAN)Architecture Based Network - EDUSAT: Architecture Based Network - EDUSATSatellites Involved - EDUSAT: Satellites Involved - EDUSAT GSAT-3 is co-located with :Technical Specifications: Technical Specifications Purpose Details Mission Education Spacecraft Mass 1950.5 Kg mass (at Lift - off) 819.4 Kg (Dry mass) Onboard Power Total four solar panel of size 2.54 M x 1.525 M generating 2040 W (EOL), two 24 AH NiCd batteries for eclipse support.

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 : Its Flexible Saves Time & Energy Study at your own pace Saves Money Mor e convenient than classroom study 24*7 access to study material & fellow students Study any topic you want to study. Drawbacks are : Time and frustration involved learning how to get on-line for novices. Occasional internet provider downtime . Student must be more active and self-directed in learning environment -Depends on individual motivation and initiative . Demands large effort and cost to develop appropriate materials . Demands large effort to create and maintain the technological infrastructure . Distance Education is not for everyone.- It is not for undisciplined learners nor inflexible instructors.My Conclusion: 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.THANK YOU: THANK YOU Delivered By :- Er.
