PSLV-C16, is the eighteenth flight of ISRO's Polar Satellite Launch Vehicle, PSLV.
In this flight, the standard version of PSLV with six solid strap-on motors is used.
PSLV-C16 places three satellites with a total payload mass of 1404 kg - RESOURCESAT-2 weighing 1206 kg,
the Indo-Russian YOUTHSAT weighing 92 kg and Singapore's X-SAT weighing 106 kg – into an 822 km polar
Sun Synchronous Orbit (SSO). PSLV-C16 launched from the First Launch Pad (FLP) at
Satish Dhawan Space Centre SHAR, Sriharikota.
The major changes made in PSLV since its first launch include changes in strap-on motors ignition sequence,
increase in the propellant loading of the first stage and strap-on solid propellant motors as well
as the second and fourth stage liquid propellant motors, improvement in the performance of the third
stage motor by optimising motor case and enhanced propellant loading and employing a carbon
composite payload adapter.
PSLV has also become a more versatile vehicle for launching multiple satellites in polar SSOs as well as Low Earth Orbits (LEO)
and Geosynchronous Transfer Orbit (GTO). With sixteen successful launches, PSLV has emerged as the
workhorse launch vehicle of ISRO and is offered for launching satellites for international customers also.
During 1994-2010 period, PSLV has launched a total of 44 satellites, of which 25 satellites are from abroad
and 19 are Indian satellites.
