• ISRO releases images of Earth captured by its EOS-06 satellite
  • EOS-6 is the third-generation satellite in the Oceansat series.
  • This is to provide continuity services of Oceansat-2 spacecraft with enhanced payload specifications as well as application areas.


  1. Ocean Color Monitor (OCM-3)
  2. Sea Surface Temperature Monitor (SSTM)
  3. Ku-Band Scatterometer (SCAT-3)
  4. ARGOS

Mission Objectives

  • To ensure the data continuity of Ocean colour and wind vector data to sustain the operational applications.
  • To improve the applications, some additional datasets such as Sea Surface Temperature and more number of bands are accommodated.
  • To develop / improve related algorithms and data products to serve in well- established application areas and to enhance the mission utility.

Other Satellites in the EOS Series

  1. EOS-01: It is an Earth Observation satellite for Agriculture, Forestry & disaster management support
  2. EOS-03: An Agile Earth Observation satellite in Geostationary orbit.
  3. EOS-04:  It is a Radar Imaging satellite meant to provide high quality images under all weather conditions.
  4. EOS-05:  Earth Observation Satellite in the Geostationary Orbit.
  5. EOS-06: Applications include ocean related services.

Earth Observation Satellites

An Earth observation satellite also called Earth remote sensing satellite is a satellite designed for Earth observation (EO) from orbit.


  • Weather
  • Environmental monitoring
  • Mapping

Geostationary orbit:

  • A geostationary orbit allows a satellite to hover over a constant spot on the earth.
  • The orbital period at this altitude is 24 hours.
  • This allows uninterrupted coverage of more than 1/3 of the Earth per satellite.
  • Three satellites, spaced 120° apart, can cover the whole Earth except the extreme polar regions.
  • This type of orbit is mainly used for meteorological satellites.
