Satellite has been launched under SSLV-D3/EOS-08 mission by the Small Satellite Launch Vehicle (SSLV)-D3 from Satish Dhawan Space Centre, Sriharikota.

  • Mission configuration is set to operate in circular Low Earth Orbit at an altitude of 475 km ( inclination of 37.4°), with a mission life of 1 year.
  • SR-0 DEMOSAT was also onboard which was developed by Space Kidz India.

Objectives of EOS-08 mission:

  • Designing and developing a microsatellite, 
  • Creating payload instruments compatible with the microsatellite bus, 
  • Incorporating new technologies required for future operational satellites.

Payloads of E0S-08 Mission: 

  • Electro Optical Infrared Payload (EOIR) payload: To take images in Mid-Wave & Long Wave Infrared band for applications like Disaster Monitoring, Environmental Monitoring etc.
  • Global Navigation Satellite System- Reflectometry payload (GNSS-R) payload: Uses remote sensing for measuring ocean winds, soil moisture, Himalayan cryosphere, etc,
  • SiC UV Dosimeter: Monitor UV irradiance at Gaganyaan mission's crew module viewport, serving as a high-dose alarm sensor for astronaut safety.

About Earth observatory satellites (EOS)

  • EOS or Earth remote sensing satellites are designed for Earth observation (EO) from orbit.
    • EO refers to collecting information about activities on Earth, both natural and artificial, including physical, chemical, biological and human systems.
  • Applications: Used in Early warning systems, environmental impact monitoring etc.

About Small Satellite Launch Vehicle (SSLV)-D3

  • SSLV-D3 is the third developmental flight of SSLV.
  • SSLV is capable of launching Mini, Micro or Nano satellites (10 to 500 kg mass) into 500km planar orbit. 
  • It uses three solid fuel-based stages and a final liquid-fuel based stage. 
  • Benefits: Low cost, low turn-around time, flexibility in accommodating multiple satellites, launch on demand feasibility, minimal launch infrastructure requirements, etc.
