OBSERVATIONS

• Internet not available on Edusat

• No exclusive structure in MHRD

• Edusat priority varies in States

• No dedicated Edusat teams/personnel in States

• Coordination mechanism between National & State

Government is required

• Funding issues:- Centrally sponsored scheme



22

OBSERVATIONS

• Content availability and Generation &

Management

• Make available all the easily content on the

network

• Generate Teacher Oriented Content• Enable Teacher to Generate own Content



Recommendations

• MHRD should manage Edusat utilization• MHRD should create a central agency for Edusat

utilization, Content Management & Coordination

• Establish technical advisory group with ISRO

• Have only National Beams on Edusat• Bunch all Broadcast Channels into a single DTH bouquet

• Reach out to Remote Areas

• Internet should be made available to users on Edusat

• All E- Journals should be made available on Edusat• Library connections should be provided to remote

colleges through Edusat 23
