India's capability in the launch vehicle
technology was first demonstrated through the
successful launch of SLV-3 in July 1980, which
placed a 40 kg Rohini satellite into a near-earth
orbit. Two more launches of SLV-3 were conducted
in May 1981 and April 1983 with the Rohini
satellites.
The SLV-3 was a four-stage,
solid-fuel, light launcher (polybutadiene). It
weighed around 17.8 tons and was 22.7 metres high
with a 1 meter diameter. Its payload mass in a
circular 500km orbit was around 40kg.
The first stage
delivered 420kN thrust in 53 seconds, the second
stage provided 200 kN thrust in 42 seconds, the third
stage delivered over 60 kN thrust in 46 sec and
the fourth stage provided about 22 kN thrust in 30 sec. Two
ballistic phases occurred during flight, one
after the second stage shutdown (until 88km
altitude) and the other after the third stage
shutdown (to reach perigee altitude).
Rockets were launched
from the Sriharikota base on the India's east
coast. This site is operational since the success
of a RH-125 sounding rocket in October '71. After
a first attempt which failed in August 1979, the
SLV-3 rocket orbited three Rohini scientific
satellites in July 1980, May 1981 and April 1983.
Then the launcher was abandoned for the ASLV.
