PSLV is capable of launching 1600 kg satellites in 620 km sun-synchronous polar orbit and 1050 kg satellite in geo-synchronous transfer orbit (GTO).
“This poses a serious limitation on launching communication satellites which are heavier. The GSLV will be capable of launching satellites which are 2000 kg - 2500 kg which matches with the GSAT class of Communication satellites”, it was noted.
Currently, India is forced to outsource the heavy launch services from abroad which are not a cost effective solution.
The establishment of a proven GSLV launcher is the need of the hour.
The successful development of indigenous cryostage will boost India's confidence in terms of its self reliance in the launch capability, ISRO officials said.
