MUMBAI: After Isro's communication satellite Insat-4CR was placed in the geosynchronous orbit, the first orbit raising manoeuvre conducted on 3 September has been successful. The satellite will be commissioned in a month's time, Isro chairman G Madhavan Nair said today.

 

Speaking to reporters on the sidelines of the second meeting of the international committee on global navigation satellite systems (ICG) in Bangalore, he said, ‘‘Tomorrow we will carry out the first orbit rising process and within a month the satellite will be operational.''

Meanwhile, the first orbit raising manoeuvre of Insat-4CR, was carried out by firing the 440 Newton Liquid Apogee Motor on board the satellite for a duration of 27 minutes by commanding the satellite from Master Control Facility (MCF) at Hassan in Karnataka.

With this operation, the perigee (nearest point to earth) of Insat-4CR has been raised to 2983 km and apogee, the farthest point to earth to 31,702 km. The inclination of the orbit with respect to the equatorial plane has been reduced to 11.1 degree.

All systems on board the satellite are functioning normally, states an official release.

Insat-4CR carries 12 high-power Ku-band transponders designed to provide Direct-To-home (DTH) television services, Video Picture Transmission (VPT) and Digital Satellite News Gathering (DSNG).

 


Insat-4CR was launched into Geosynchronous Transfer Orbit by the fifth flight of Isro's Geosynchronous Satellite Launch Vehicle (GSLV-F04) on 2 September from Satish Dhawan Space Centre (SDSC), Sriharikota.
