Insat 3D [ISRO]
INSAT-3D is a pure meteorological satellite without additional communication payload as in the other INSAT satellites. It features a 19-channel sounder, a 6-channel imager and a DRT & SAR payload.
The satellite was originally to be launched on an Indian GSLV rocket, but was after long delays finally launched on an Ariane-5ECA booster.
After launch, INSAT-3D displayed "anomalous behavior" after deploying its solar panel. The spacecraft lost communications with the ground and started to spin up. Engineers were able to restore communications with the spacecraft and restore normal operations, but it was unclear if the spacecraft suffered any permanent damage from the anomaly.
A improved replacement, INSAT 3DR is being constructed for a launch readyness in 2015. An additional ground spare, INSAT 3DS is also under construction.
