CHENNAI: India's advanced weather satellite Insat-3D, had developed some anomalies after it was launched in the early hours of July 26 from Kourou, French Guyana, but Indian scientists corrected these immediately.
The satellite has now been successfully placed in a geosynchronous orbit, the Indian Space Research Organisation (Isro) said in a statement on Thursday. Insat-3D will eventually be placed in a geostationary orbit from where it can monitor weather conditions over the same region continuously.
The satellite reached the intended path after three orbit-raising manoeuvres commanded from Isro's master control facility at Hassan. It wasn't a textbook launch of the satellite, as soon after the deployment of its solar panels, the satellite showed some "anomalous behaviour," according to Isro scientists. However, the mission operations team of Isro soon brought the satellite by firing thrusters and using other contingency procedures before raising its orbit.
The Isro statement said Insat-3D is now moving towards its final geostationary orbital location of 82 degree East longitude and on August 6, 2013 it will reach this destination.
"Subsequently, the two meteorological payloads (Imaging System, Atmospheric Sounder), as well as the two Transponders (designed for the Meteorological Data Relay and Satellite-aided Search and Rescue system) will be activated by August 8, 2013," it said.
Before reaching the 36,000km orbit, the satellite is now on a slightly elliptical path with an apogee (farthest point to earth) of 35,799km and a perigee (nearest point to Earth) of 35,469km.
