Indian space scientists provided a concrete shape to the launch of 'Stretched Rohini Satellite Series - SROSS' by making changes in the technology of the general Rohini satellites launched. For this, they used "Enhanced Satellite Launch Vehicle", based on fully indigenous technology, in place of Foreign Vehicle SLV-3.
After this, 3 satellites of this series SROSS-1, SROSS-2, SROSS-3 and three launchers ASLV-D1, ASLV-D2 and ASLV-D3 were launched in space.
On March 24, 1987, the first satellite SROSS-1 of the extended Rohini series (from Sriharikota Launch Station) was launched in space with the help of augmented satellite launcher 'ASLV-D1', but only after 153 seconds of launch, due to technological failure in the launcher vehicle, it was destroyed with the satellite and fell into the Bay of Bengal.
Thus, the launcher vehicle, built for the purpose of launching out-of-the-air satellites, failed in its pilot flight, and it also badly affects the creation of satellites with overloaded loads made by indigenous technology in the country.
The second satellite SROSS-2 of the extended Rohini series was launched from Sriharikota launch center on 13 July 1988 through the second generation satellite launcher ASLV-D2 but it was also unsuccessful as after 2 minute 20 second, the Satellite burnt in air.
Failure of two consecutive experimental flights shocked the Indian space program and it was also suspected that the creation and development of future Polar Satellite Launch Vehicle (PSLV) is not possible in such circumstances. The usefulness of Sriharikota Launch Center was also questioned for this work but due to the intensive scrutiny of the reasons for these failures, the third experimental flight was successful.
From the Sriharikota launch center on May 20, 1992, the third and last satellite SROSS-3 of the extended Rohini series was launched in space with the help of augmented satellite launcher ASLV-D3. This become successful and it set the satellite of 106 kilograms in a fixed class at an altitude of 450 km. The minimum distance of the Earth from its orbit is 261 kilometers and the maximum distance is 420 kilometers.
This satellite revolves around Earth in a rotation of 92 minutes. In this satellite, Retraction Potassium Analyzer (RPA) is also used in addition to the instruments used for study of gamma ray. After this success, India's position has been established in the frontline of developing countries along with Israel and Brazil.
On May 4, 1994, the last satellite SROSS-C2 of the Rohini series was successfully launched through the Promoter Flight ASLV-D4.
