What is an Earth Observing Satellite?

  • A satellite which through space sends signals to Earth and monitors the changes which occur on the Earth’s surface is called an Earth Observing Satellite (EOS). 
  • These satellites can only be used for non-military purposes and mainly for environmental benefits
  • The first EOS which was launched by ISRO was in the year 1988 and was named IRS-1A
  • Currently, there are seventeen such remote sensing Indian satellites present in the orbit. Thirteen of which are in Sun-synchronous orbit and the rest four are in Geostationary orbit
  • Few of the important Earth Observing Satellites include: RISAT-2BR1, Cartosat Series, SCATSAT-1, INSAT-3D, IMS, Bhaskara-I, and Bhaskara-II

Another important Earth Observing Satellite is to be launched by NASA and ISRO tentatively in 2022. The mission has been named NASA-ISRO Synthetic Aperture Radar (NISAR) and is believed to be one of the most expensive Earth-imaging satellites.
