ISRO developed the Small Satellite Launch Vehicle (SSLV) to deliver payloads of up to 500 kilograms to low Earth orbit (LEO) and 300 kilograms to Sun-synchronous orbits.
HAL was selected from a pool of nine bidders for the SSLV contract because it submitted the highest-ranked techno-commercial bid.
HAL won the contract to manufacture, market, and launch the SSLV, marking the first time ISRO has transferred a complete technology package to a single agency.
The SSLV is a four-stage launch vehicle consisting of three solid-propulsion stages and a liquid-propulsion Velocity Trimming Module (VTM) as the terminal stage.
ISRO started developing the SSLV in 2017 to meet the need for small satellite launchers.
A new launch site for SSLV launches is being developed near Kulasekharapatnam in Tamil Nadu and is expected to become operational within a year.
HAL is expected to prepare for a minimum of six to eight SSLV launches per year.
ISRO decided to focus solely on designing, developing, and testing the SSLV technology before transferring it to other agencies for mass production and launches.
ISRO has conducted three launches of the SSLV, with the first launch on August 7, 2022, failing, and the subsequent two launches in 2023 and 2024 being successful.
The SSLV features low cost, a quick turnaround time of approximately 72 hours or less, flexibility in accommodating multiple satellites, and minimal launch infrastructure requirements.
The Indian government awarded the contract for SSLV technology transfer to Hindustan Aeronautics Limited (HAL), a public sector aerospace and defense company established in 1940.
ISRO’s Small Satellite Launch Vehicle (SSLV) program is affected because the PSLV’s third-stage motor is virtually identical to the SSLV’s second-stage motor.
Indian Space Research Organisation plans a launch of the SSLV solid rocket in 2025.
India launched the EOS-08 Earth observation satellite on a solid SSLV rocket in September 2024.
India's Small Satellite Launch Vehicle (SSLV) successfully launched for the first time in 2023.
JANUS-1 was launched aboard ISRO’s Small Satellite Launch Vehicle (SSLV-D2) on 2023-02-10.
JANUS-1 rode on the Indian Space Research Organization’s SSLV-D2 rocket launched from the Satish Dhawan Space Centre under a commercial arrangement with New Space India Limited (NSIL).

The second developmental flight of the Small Satellite Launch Vehicle, SSLV-D2, launched on 2023-02-10 at 09:18 IST.
ISRO developed SSLV to provide cheaper and more flexible access to space compared to its Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV).
