'''INSAT-4E''', also known as '''GSAT-6''', is a member of the INSAT family and is a multimedia communication satellite that will offer a Satellite Digital Multimedia Broadcasting (S-DMB) service across several digital multimedia terminals or consoles which can be used to provide information services to vehicles on the fly and to the mobile phones. The satellite can be used for other social and strategic applications.<ref>{{cite web|url=http://www.spacedaily.com/news/india-05zzv.html |title=ISRO proposes INSAT-4E satellite|publisher=spacedaily.com|access-date=2012-05-29}}</ref>
