GISAT-1 Being Planned by ISRO

  • Indian Space Research Organisation (ISRO) plans to launch GISAT-1 into space using GSLV-F10 rocket.
  • Geo Imaging Satellite-1 or GISAT-1 is India’s first earth observation satellite in a geostationary orbit.
  • The rocket will place GISAT-1 in geosynchronous orbit, and subsequently in geostationary orbit, using its onboard propulsion system.
  • GISAT-1 will facilitate near real-time observation of the Indian sub-continent, under cloud-free condition, at frequent intervals.
  • With onboard high resolution cameras, the satellite will allow India to monitor the Indian land mass and the oceans, particularly its borders.
  • It would help in quick monitoring of natural disasters, episodic and any short-term events.
  • It will obtain spectral signatures of agriculture, forestry, mineralogy, disaster warning, cloud properties, snow and glacier and oceanography.

Earth Observation Satellites

  • It is a remote sensing satellite designed for Earth observation (EO) from orbit, including spy satellites and those used for non-military uses.
  • Starting with IRS-1A (1988), ISRO has launched many operational remote sensing satellites.
  • 13 satellites in Sun-synchronous orbit - Resourcesat-1, 2, 2A; Cartosat-1, 2, 2A, 2B; RISAT-1,2; Oceansat-2; Megha-Tropiques; SARAL; SCATSAT-1.
  • 4 satellites in Geostationary orbit – Kalpana; INSAT 3A, 3D, 3DR.
  • These satellites provide data in diversified spatial, spectral and temporal resolutions to cater to different user requirements - agriculture, water resources, urban planning, mineral prospecting, environment, etc.
