The Small Satellite Launch Vehicle (SSLV) is a compact, cost-effective rocket developed by the Indian Space Research Organisation (ISRO) to cater to the growing global demand for launching small satellites. Designed for rapid deployment and flexibility, the SSLV aims to revolutionize satellite access by offering quicker turnaround times and reduced costs compared to traditional launch vehicles.
What Is SSLV?
The SSLV is a three-stage launch vehicle that combines solid propulsion stages with a liquid-based Velocity Trimming Module (VTM) for precise orbital insertion. Standing at 34 meters tall and with a diameter of 2 meters, the SSLV has a lift-off mass of approximately 120 tonnes. It is engineered to launch payloads ranging from 10 kg to 500 kg into Low Earth Orbit (LEO) at an altitude of 500 km. ISRO
