This is the second time that PSLV
is launching three satellites simultaneously; in the previous launch in May
1999, PSLV had launched Indian IRS-P4, German DLR-TUBSAT and Korean KITSAT-3.
While TES and BIRD will be placed in a 568 km sun-synchronous orbit, the third
satellite, PROBA, will be placed in an elliptical orbit of 568 x 638 km, which
will be achieved by firing the Reaction Control Thrusters of the fourth stage
of PSLV-C3. As all other Indian satellite launch vehicles, PSLV-C3, is launched
from Satish Dhawan Space Centre, SHAR on the east coast of India.
