Small Satellite Launch Vehicle

For the earlier launch vehicle developed by India, see Satellite Launch Vehicle.

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 600 kg (1,300 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 no earlier than December 2021, from the First Launch Pad, and in the future a dedicated launch pad in Sriharikota called Small Satellite Launch Complex (SSLC) will be set up. A new spaceport, under development, near Kulasekharapatnam in Tamil Nadu will handle SSLV launches when complete.

After entering the operational phase, the vehicle's production and launch operations will be done by a consortium of Indian firms along with NewSpace India Limited (NSIL).

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 is120 crore (US$16 million) and the manufacturing cost is expected to be30 crore (US$4.0 million) to35 crore (US$4.6 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.

Vehicle characteristics:

  • Height: 34.0 meters
  • Diameter: 2.0 meters
  • Mass: 120 tonnes

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 new spaceport, under development, near Kulasekharapatnam in Tamil Nadu will handle SSLV launches to Sun-synchronous orbit when complete.

To qualify for flight, SSLV's solid first stage SS1 has to perform two consecutive nominal static fire tests.

First static fire test of SS1 conducted on 18 March 2021 was unsuccessful. About 60 seconds into the test, oscillations were observed and after 95 seconds the nozzle of SS1 stage disintegrated. The nominal duration of test was 110 seconds.
