Rohini Satellite 1 or RS-1 is the first satellite successfully launched by India using indigenously developed rockets. After the launch on 18 July 1980 by a SLV rocket, India became the 7th country to have rocket launching capability.
The satellite was spin-stabilised and provided data regarding the fourth stage of SLV rocket.[1]
