Well done ISRO

Congratulations to the ‘Team ISRO’ for yet another successful launch of, INSAT (Indian National satellite)-3DR, an advanced weather satellite, in a hat-trick of successful launch of indigenously developed cryogenic engine based Geosynchronous Satellite Launch Vehicle (GSLV) on 8th September 2016. It took only 17 min after take-off to place the satellite into the Geosynchronous Transfer Orbit (GTO) at a perigee of 169.7 km, which was very close to its before launch aim of placing it at a perigee of 170 ± 5 km. ISRO could save half of the launch cost (Rs. 400 crore) by doing this feat indigenously. The INSAT- 3 DR can help in taking the images of the Earth once in every 26 minutes, besides measuring the surface temperature of sea and snow cover, wind speed, etc. This satellite can also pick up and relay alert signals received from the distress beacons of aviation, maritime and other users to the control centre thus can help fishermen, Coast guards, Airport authorities, shipping and Defence forces, etc. This successful launch through GSLV may bring good business of satellite launches to ISRO and to the country in the coming period.  

Dr S V N Vijayendra, Mysuru
