ISRO to launch Singapore’s TeLEOS-2 satellite

Published: 20th Apr, 2023


The Indian Space Research Organisation (ISRO) is gearing up for its next big mission to launch a customer satellite in an orbit around the planet. The TeLEOS-2 mission will launch on-board ISRO's workhorse Polar Satellite Launch Vehicle (PSLV) on its 55th mission to date.

What is TeLEOS-2 satellite? 

  • The Singaporean probe is an Earth Observation Satellite, which has been designed to capture round-the-clock, all-weather satellite imagery.
  • The 750-kilogram satellite, developed by ST Engineering, will provide imagery that could be used for hotspot monitoring and haze management, air crash search and rescue operations, and much more.
  • The XL variant of PSLV, which will be used during the C-55 mission, has 6 solid rocket strap-on motors to augment the thrust. 
  • The rocket is capable of launching 1,750 kg of payload to Sun-Synchronous Polar Orbits at 600 km altitude and 1,425 kg into Geosynchronous and Geostationary orbits.


  • The PSLV is a third-generation launch vehicle developed solely in India and was the first launched from India to be equipped with liquid stages. 
  • The rocket is capable of placing multiple payloads into orbit and has been used to launch various satellites into Geosynchronous and Geostationary orbits.
  • During its last mission, PSLV deployed an Earth Observation Satellite (EOS-06) and eight nano-satellites with a lift-off mass of 321 tonnes into orbit. 
  • The Primary satellite (EOS-06) was separated in Orbit-1. 
  • Subsequently, orbit change was conducted using two Orbit ChangeThrusters (OCTs) introduced in the Propulsion Bay Ring of the PSLV-C54 Vehicle.

Previous Launches

  • The Indian space agency launched three Singaporean satellites with the PSLVC-53 mission in June 2022. 
  • The spacecraft carried the DS-EO satellite, NeuSAR, a 155 kg satellite, and Scoob-1 of Nanyang Technological University (NTU),
