Airbus supports monitoring climate change in France and India with TRISHNA


The French space agency (Center National d’Etudes Spatiales, CNES) has signed a contract with Airbus Defense and Space for the development and manufacture of the infrared thermal instrument for the TRISHNA satellite.

TRISHNA (Thermal Infrared Imaging Satellite for High Resolution Natural Resources) is the latest satellite in the Franco-Indian satellite fleet dedicated to climate monitoring and operational applications. CNES and the Indian Space Research Organization (ISRO) are joining forces to develop an infrared observation system with high thermal resolution and high revisit capacity comprising a satellite and an associated ground segment.

TRISHNA’s observations will provide a better understanding of the water cycle and improve the management of the planet’s precious water resources in order to better define the impacts of climate change, particularly at the local level.

As part of the international partnership, ISRO will provide the platform, the short-wave infrared instrument and will be the prime contractor for the satellite, while CNES is co-responsible for the mission and will supply the thermal infrared instrument, which will be developed by Airbus. . The ground segment is shared between the two countries.

For this mission, Airbus relies on the latest innovations and synergies from other programs (IASI-NG, CO3D, etc.) to offer an efficient and affordable instrument, with the aim of promoting the development of a commercial market.

The mission will also serve many other applications: monitoring of continental and coastal waters, monitoring of urban heat traps, risk monitoring (detection of fires and volcanic activity), study of the cryosphere (glaciers, frozen lakes) and assessment of the radiation balance. .

Jean-Marc Nasr, head of space systems at Airbus, said: “Thanks to ambitious scientific missions like TRISHNA, our industry has reached a technological maturity which opens a new era of commercial observation of the Earth and all associated applications . The expertise of France, the world leader in the export market for Earth observation, combined with the unrivaled efficiency and ambition of the Indian space industry will bring thermal infrared imaging to a new level. This will allow revolutionary applications in agriculture, urban and coastal management, meteorology, climate science and many commercial applications. “
