  • It is designed to capture round-the-clock, all-weather satellite imagery of the Earth.
  • It features synthetic aperture radar which can provide data in 1-metre resolution.
  • It will provide imagery that will be used for hotspot monitoring and haze management, along with assistance in aviation accidents, search and rescue operations, and more.
  • TeLEOS-2 will be launched aboard ISRO’s Polar Satellite Launch Vehicle (PSLV), which will take off on its 55th mission.
  • The ISRO will use the XL variant of PSLV in the upcoming C-55 mission. 

Note: This is also not the first time the ISRO will be launching a Singaporean satellite from India. It launched three Singaporean satellites with the PSLVC-53 mission in June 2022 and in 2015, the ISRO launched the TeLEOS-1, which was the first Singapore commercial Earth Observation Satellite.

About PSLV

  • The Polar Satellite Launch Vehicle (PSLV) is the first Indian launch vehicle with liquid stages.
