== Mission ==
The mission goal is stated as "to provide an operational, environmental & storm warning system to protect life & property and also to monitor earth’s surface and carryout oceanic observations and also provide data dissemination capabilities."

=== Payloads ===
The satellite has 4 payloads:
*6 channel multi-spectral Imager
*19 channel sounder
* Data Relay Transponder (DRT)
* Satellite Aided Search and Rescue (SAS&R)

=== Launch ===
The satellite was expected to be launched using the GSLV Mk-II. On December 4, 2010, ISRO Chairman revealed that ISRO was considering the use of an Ariane 5 ECA launch vehicle for the launch.<ref name="Dec4" /> The launch was successfully carried out on 26 July 2013 from [[French Guiana]].<ref>{{cite web | url=http://www.wmo-sat.info/oscar/satellites/view/193 | title=Satellite: INSAT-3D | publisher=Observing Systems Capability Analysis and Review Tool | access-date=November 16, 2012}}</ref> INSAT-3D was launched along with [[AlphaSat]], which is Europe's largest telecommunication satellite.<ref>{{cite web|url=http://www.esa.int/Our_Activities/Telecommunications_Integrated_Applications/Alphasat/Flawless_launch_of_Alphasat_Europe_s_largest_and_most_sophisticated_telecom_satellite|title=Flawless launch of Alphasat, Europe's largest and most sophisticated telecom satellite|publisher=www.esa.in|access-date=25 July 2013}}</ref><ref>{{cite web|url=http://www.space.com/22134-ariane5-rocket-launch-india-satellites.html|title=Europe's Largest-Ever Telecommunications Satellite Launches With Indian Weather Probe|publisher=www.space.com|access-date=26 July 2013}}</ref>
