India’s Advanced Weather Satellite INSAT-3D successfully placed

INSAT 3D, an advanced weather satellite.

In country like India 70% of country either directly or indirectly depends upon agriculture and it majorly depends upon weather. To improve nation’s weather observation ISRO formed a series of INSAT satellites.

History of INSAT satellites	Year of Launch
INSAT 1A	1982
INSAT 1B	1983
INSAT 1C	1988
INSAT 1D	1990
INSAT 2A	1992
INSAT 2B	1993
INSAT 2E	1999
INSAT 3D	2013

INSAT 3D spacecraft was supposed to be placed in Geosynchronous orbit at 36000 Km. INSAT 3D is carrying 19 channel sounder, 6 channel imager, Data Related Transponder and Satellite Aided Search and Rescue Payloads. The imagers will scan full earth disc in less than 30 minutes . Sounder will scan indian land marks every hour and indian ocean every 6 hour.

Through data given by imagers and sounders scientist can get a 3 dimensional pictures of temperature, humidity and Ozone.

India’s Weather Satellite INSAT 3D, carrying advanced weather monitoring payloads, was launched successfully in the early hours of today (July 26, 2013) by Ariane-5 (VA214) launch vehicle from Kourou, French Guiana.

After a smooth countdown lasting 11 hours and 30 minutes, the Ariane-5 launch vehicle lifted off right on schedule at the opening of the launch window at 01:24 hours IST. After a flight of 32 minutes and 48 seconds, INSAT-3D was placed in an elliptical Geosynchronous Transfer Orbit (GTO), very close to the intended one.

Now INSAT 3D has been successfully placed in Geosynchronous orbit
