Small Satellite Launch Vehicle ­D2

Context: 

The Indian Space Research Organisation (ISRO) will undertake the second development flight of the Small Satellite Launch Vehicle (SSLV) from Sriharikota. 

About the News:

• The vehicle is intended to inject the ISRO’s EOS­07, the U.S.­based firm Antaris’s Janus­1 and the Chennai Based space start­up Space Kidz’s AzaadiSAT­2 satellites into a 450­km circular orbit in its 15­minute flight.

EOS­07:

•  The EOS­07 is a 156.3­kg satellite designed, developed and released by the ISRO.

•   Objective: To design and develop payload instruments compatible with micro satellite bus and technologies that are required for future operational satellites.

• It would design and develop a micro satellite accommodating new technology payloads in a quick turnaround time.

Janus­1:

• Weighing around 10.2 kg, Janus­1 is a technology demonstrator, smart satellite mission based on the Antaris software platform.

 AzaadiSAT­2:

• AzaadiSAT­2 is a 8.7­kg satellite – a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai.

Small Satellite Launch Vehicle:

• Small Satellite Launch Vehicle (SSLV) is a 3 stage Launch Vehicle configured with three Solid Propulsion Stages and liquid propulsion based Velocity Trimming Module (VTM) as a terminal stage.

•   SSLV caters to the launch of satellites weighing up to 500 kg to low earth orbits on a ‘launch on demand’ basis.

•   It provides low cost access to space, offers low turnaround time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure.
•  It is configured with three solid propulsion stages and a velocity terminal module.
• It is a 34­m ­tall, 2m diameter vehicle with a lift­off mass of 120 tonnes.

•  Payload Capability:

• • Single/Multi Satellites – Nano, Micro and Mini satellites

• • Single Satellite up to 500 kg in 500 km planar orbit

• • Three Multiple satellites ranging from 10 kg to 300 kg into 500 km Planar Orbit
