PSLV-C2 · Lablypedia

In a nutshell

PSLV-C2 was the second operational launch and overall fifth mission of the Polar Satellite Launch Vehicle (PSLV) program. This launch was also the forty-third launch by Indian Space Research Organisation (ISRO) since its first mission on 1 January 1962. The vehicle carried three satellites which were deployed in the Sun-synchronous low Earth orbit. The vehicle carried India's first remote sensing satellite Oceansat-1 (IRS-P4) as the main payload. It also carried South Korean satellite KITSAT-3 and German satellite DLR-Tubsat as auxiliary payloads. PSLV-C2 was the first Indian Expendable launch vehicle to carry and deploy more than one satellite in a mission. This was also India's and ISRO's first commercial spaceflight where South Korea and Germany each paid US$1.0 million (equivalent to $1.93 million in 2025) to ISRO for launching their satellites.
