TRISHNA Satellite

About TRISHNA Satellite:       

• The TRISHNA (Thermal Infra-Red Imaging Satellite for High-resolution Natural Resource Assessment) is a collaborative endeavor between the Indian Space Research Organisation (ISRO) and the French Space Agency Centre National d’Etudes Spatiales (CNES).
• It is the third satellite that India and France are developing after Megha-Tropiques and SARAL (Satellite with ARGOS and ALTIKA) satellites.
• Objectives:
  • Detailed monitoring of the energy and water budgets of the continental biosphere for quantifying terrestrial water stress and water use.
  • High-resolution observation of water quality and dynamics in coastal and inland waters.
  • A comprehensive assessment of urban heat islands detection of thermal anomalies linked to volcanic activity and geothermal resources.
  • Precise monitoring of snow-melt runoff and glacier dynamics. 
  • Provide valuable data on aerosol optical depth, atmospheric water vapor, and cloud cover. 
• Payloads:
  • Thermal Infra-Red (TIR) Payload: It is provided by CNES and features a four-channel long-wave infrared imaging sensor capable of high-resolution surface temperature and emissivity mapping.
  • Visible – Near Infra-Red – ShortWave Infra-Red (VNIR-SWIR) payload: It is developed by ISRO, includes seven spectral bands designed for detailed mapping of surface reflectance of VSWIR bands for generating important biophysical and radiation budget variables.
• Function: It is engineered to deliver high spatial and high temporal resolution monitoring of the earth’s surface temperature, emissivity, and biophysical and radiation variables for surface energy budgeting at regional to global scale.
