GSLV-Mark 1 and 2 are capable of placing the Insat-II class of satellites (2,000-2,500 kg) into geosynchronous transfer orbit.
“GSLV is an excellent vehicle, a beautiful vehicle. As compared to the PSLV [Polar Satellite Launch Vehicle], it is much less complex, except for one stage. It is far simpler to handle, though it has a large number of control components,” Radhakrishnan says.
The GSLV is the second satellite launch vehicle developed by ISRO, after the PSLV, which has successfully completed 22 launches in a row.
