EOS-05

EOS-05, also designated GISAT-1A, is India's first dedicated geostationary Earth observation satellite. From geostationary orbit it can image the entire Indian landmass approximately every 30 minutes and selected sectors every 5 minutes, supporting disaster monitoring - cyclones, floods, forest fires - as well as agriculture and border surveillance.

The mission replaces EOS-03 (GISAT-1), which was lost in August 2021 when the cryogenic upper stage of its GSLV Mk II failed to ignite after the second stage.
