The Small Satellite Launch Vehicle (or SSLV) is a small-lift launch vehicle being developed by the Indian Space Research Organisation (ISRO) with payload capacity to deliver 500 kg (1,100 lb) to low Earth orbit (500 km (310 mi)) or 300 kg (660 lb) to Sun-synchronous orbit (500 km (310 mi)) for launching small satellites, with the capability to support multiple orbital drop-offs. On 21 December 2018, the Vikram Sarabhai Space Centre (VSSC) at Thumba completed the design for the vehicle.
The maiden flight is expected in 2021, and all flights will launch from a dedicated launch pad in Sriharikota called Small Satellite Launch Complex (SSLC). A new spaceport, under development, near Kulasekharapatnam in Tamil Nadu will handle SSLV launches when complete.
The SSLV was developed with the aim of launching small satellites commercially at drastically reduced price and higher launch rate as compared to Polar Satellite Launch Vehicle (PSLV). The development cost of SSLV is ₹120 crore (US$17 million) and the manufacturing cost is expected to be ₹30 crore (US$4.2 million) to ₹35 crore (US$4.9 million).
The projected high launch rate relies on largely autonomous launch operation and on overall simple logistics. To compare, a PSLV launch involves 600 officials while SSLV launch operations would be managed by a small team of about six people. The launch readiness period of the SSLV is expected to be less than a week instead of months. The launch vehicle can be assembled both vertically like the existing PSLV and Geosynchronous Satellite Launch Vehicle (GSLV) and horizontally like the decommissioned Satellite Launch Vehicle (SLV) and Augmented Satellite Launch Vehicle (ASLV).
The first three stages of the vehicle use solid propellant, with a fourth stage being a velocity-trimming module.
- Height: 34.0 meters
- Diameter: 2.0 meters
- Mass: 120 tonnes
Small Satellite Launch Complex
The early developmental flights and those to inclined orbits will launch from Sriharikota, at first using existing launch pads and later from dedicated facility called Small Satellite Launch Complex (SSLC). Tenders related to manufacturing, installation, assembly, inspection, testing and Self Propelled launching Unit (SPU) were released in October 2019.

A study has been carried out to identify suitable locations for establishment of a launch pad for the small satellite launch vehicle. It was found that the locations in the western sea coast near Gujarat did not meet some of the criteria for establishing the launch pad.
