Stretched Rohini Satellite Series (SROSS) 3 & C2
ISRO) developed the Stretched ROhini Satellite Series (SROSS) for conducting various scientific experiments as well as for new and novel application-oriented missions. The first 2 satellites in the series did not make it into orbit due to launch vehicle failure. The third, SROSS 3 (also known as SROSS C), successfully attained an orbit on 20 May 1992. Although they decayed rapidly, the orbital parameters were initially: apogee ~ 430 km, perigee ~ 255 km, and orbital inclination ~ 46 degrees. The satellite spin period was 10.6 s. The satellite carried a gamma-ray burst (GRB) experiment and a Retarded Potential Analyzer (RPA) payloads. The spacecraft reentered the Earth's atmosphere on 14 July 1992. SROSS C2, launched on 4 May 1994 with an Indian Augmented Satellite Launch Vehicle (ASLV-D4), operated at 420 X 620 km orbit with an inclination of 42 degrees. It reentered the atmosphere in 2001 and is not presently operating.
During the mission lifetime, 53 triggers occurred. Most of these, as expected, were false. There were 8 candidates for "real" bursts. One event, on 22 June, was also seen by CGRO and is believed real. Two other events could be real, as CGRO was not recording data at the time and so could not corroborate their occurrence.
