CRYOGENIC 2LST

ISRO conducted previous GSLV flights with the help of
readymade cryogenic engines procured from Russia earlier.
"GSAT-4 is the only payload (to be carried by
GSLV-D3). But GSAT-4 contains several payloads. We are getting
into Ka-band transponder system there, and we are also having
a small payload for the satellite navigation for augmenting
the GPS system that is GAGAN (GPS Aided GEO Augmented
Navigation)," Radhakrishnan said.
ISRO is also trying electric propulsion system for the
first time. "Instead of using liquid fuel for station-keeping,
here you are using electric propulsions", he said, noting the
move would enable the agency to extend the life of satellites
by a couple of years.
"This is a new technology. First time, we are trying
it," he said. PTI RS
