The Rohini Satellite Series is a group of Indian satellites developed by the Indian Space Research Organisation (ISRO). Launched between 1980 and 1994, these satellites were primarily designed for Earth observation and remote sensing applications. The series played a crucial role in gathering data for agriculture, forestry, and land-use planning. The first satellite in the series, Rohini-1, was launched in 1980 using the Satellite Launch Vehicle (SLV). Over the years, the series expanded to include several models, each improving upon the last in terms of technology and capabilities. The Rohini satellites significantly contributed to India's advancements in space technology and satellite communication.
