'''Rohini''' series is a series of sounding rockets developed by [[ISRO]] for meteorological and atmospheric study purposes. The rockets in this series are named RH an abbreviation of rohini, followed by a numeral indicating its diameter. India currently operates four versions of the Rohini sounding rocket: the RH-200, the RH-300, the RH-300 Mk II and the RH-560 Mk II .RH200 and RH560 are two stage rockets while RH300 is a single stage rocket. Three of them use solid propellants. RH560 Mk II can carry a payload of 100 Kg to an altitude of about 400 Km.

Uses

RH200 is used for meteorological studies, RH300 Mk II for upper atmospheric studies and RH560 Mk II for ionospheric studies. RH200 was used as the rocket for the first payload launch in India solely made by students. It was the contribution of students of VIT University, Vellore
