ISRO Successfully Puts GSAT-8 into
Geosynchronous Orbit
Bangalore : Indian Space Research
Organization (ISRO) on Wednesday
successfully advanced communication
satellite GSAT-8 to geosynchronous orbit
with an orbital period of 23 hours and 45
minutes.
Information to this effect was made by
ISRO that the satellite's orbit has a perigee
(closest point to Earth) of 35,543 km, an
apogee (farthest point to Earth) of 35,770
km and an orbital inclination of 0.04 degree
with respect to the equatorial plane.
Solar arrays on both sides of the satellite have been deployed and they are tracking the sun and
generating electrical power, the Bangalore-based ISRO said on Wednesday.
These solar arrays are designed to generate 6,240 W of electrical power. Two large dual grid
Ku-band antennae have been opened and are pointing towards the Earth, it said.
On Wednesday, the satellite was put into the final orbital configuration pointing towards the
Earth continuously.
GSAT-8 is presently located at 47 degree East longitude and is being moved towards its final
orbital position of 55 degree East, where it will be co-located with the INSAT-3E satellite.
In Orbit Testing of 24 Ku-band transponders of GSAT-8 is scheduled to begin on 1st
June and the satellite is expected to be ready for service in about a month, it said.
Testing of GAGAN navigational payload would be conducted from the new Navigation Control
Centre at Kundanahalli near Bangalore.
Launch Date | 21.05.2011 | |
GSAT-8, India’s advanced communication satellite, is a high power communication satellite being inducted in the INSAT system. Weighing about 3100 Kg at lift-off, GSAT-8 is configured to carry 24 high power transponders in Ku-band and a two-channel GPS Aided Geo Augmented Navigation (GAGAN) payload operating in L1 and L5 bands. The 24 Ku band transponders will augment the capacity in the INSAT system. The GAGAN payload provides the Satellite Based Augmentation System (SBAS), through which the accuracy of the positioning information obtained from the GPS Satellite is improved by a network of ground based receivers and made available to the users in the country through the geostationary satellites. | ||
