Returning to India the same year, he joined Indian Space Research Organization (ISRO) where he would work for the rest of his life.
Srinivasan's early assignments at ISRO included the development of Rohini satellite and later, the initiation of satellite launch vehicle (SLV) from 1973 onwards. In 1980, when A. P. J.
