xxxii.2. Operational EOS of India

Following are the earth observation satellites that are currently operational in India

  • 14 in SSPO (Resourcesat-2; Cartosat-1, 2, 2A and 2B; Risat-1 and 2, 2B, 2BR 1, 2BR2(EOS-01), 1B(EOS-04); Oceansat 2, SARAL, OceanSat 3(Nov 2022).
  • 3 in GEO (INSAT-3D, Kalpana-1 and INSAT BA)
  • 1 in equatorial orbit (Megha-Tropiques).

RISAT series

  • Radar imaging satellite series with resolution less than 1 m
  • Active remote sensing satellite: beam a radio signal on the earth’s surface and ‘senses’ the radio signal reflected back giving them all-weather and day-and-night observing capability.
  • ISRO has launched 7 satellites in the RISAT series so far. Risat-2A is yet to be launched.
  • Applications: Agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, flood monitoring and military surveillance.

CARTOSAT series

  • Remote sensing satellite dedicated to cartographic applications.
  • Earlier versions were panchromatic (senses visible light across all colours, violet to red). Cartosat-2C onwards multi-spectral scanners are used and Cartosat 3 has a hyperspectral scanner.
  • General applications: Cartography for large scale urban planning, rural resource and infrastructure development, Land Information System and GIS application, coastal land use etc.

ResourceSat series

  • Natural resource monitoring satellites
  • Medium resolution, wide swath satellites with multispectral scanners
  • Applications: Advanced land and water resource management applications.

OceanSAT series

  • Dedicated EO satellite for ocean monitoring.
  • Multispectral microwave sensor to measure sea surface temperature, wind speed, cloud water content and water vapour content in the atmosphere above the ocean.
  • Application: Study of chlorophyll concentration, phytoplankton blooms, atmospheric aerosols and suspended sediments in the water.
  • Includes OceanSAT 1, 2, and 3 and 3A.
  • OceanSAT 3(named EOS-06) was launched in November 2022.

GiSat series: Geo-imaging satellites

  • 1st among remote-sensing satellite in geosynchronous orbit. (normally they are in SSPO)

Status

  • GiSat-1(EOS-03) launch in 2021 failed
  • GiSat-2(EOS-05) is a dedicated military satellite to be acquired by Indian Navy. Launch date to be decided.

Significance

  • Currently imaging satellites map a particular area only once in 22 days. GiSat can scan or map an area every 2nd day as it will be placed in geostationary orbit.
