From UPSC perspective, the following things are important :

Prelims level : EOS-01

Mains level : Not Much

India would launch its latest earth observation satellite EOS-01 and nine international customer spacecraft onboard it’s PSLV-C49.

Try this PYQ:

Q.The term ‘IndARC’, sometimes seen in the news, is the name of:

(a) An indigenously developed radar system inducted into Indian Defence

(b) India’s satellite to provide services to the countries of Indian Ocean Rim

(c) A scientific establishment set up by India in Antarctic region

(d) India’s underwater observatory to scientifically study the Arctic region


  • EOS-01 is intended for applications in agriculture, forestry and disaster management support.
  • This is the first launch by the Indian Space Research Organisation since the COVID-19-induced lockdown came into force in March.
  • This will be the 51st mission of ISRO’s workhorse, the Polar Satellite Launch Vehicle.

What is Earth Observation Satellite (EOS)?

  • An EOS or remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others.
  • Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites.
  • Today, India has one of the largest constellations of remote sensing satellites in operation.
  • Currently, *thirteen* operational satellites are in Sun-synchronous orbit and *four* in Geostationary orbit.
  • The data from these satellites are used for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.
