Singapore Satellites Launched By ISRO


The Indian Space Research Organization’s Polar Satellite Launch Vehicle (PSLV-C55) lifted off from the Satish Dhawan Space Centre in Sriharikota on Saturday, carrying two Singapore spacecraft, TeLEOS-2 as primary and Lumelite-4 as co-passenger.

Points to Ponder

  • The mission was a dedicated commercial PSLV flight of NewSpace India Limited (NSIL) for a Singapore-based multinational satellite customer.
  • The PSLV-C55 was carrying two Singapore satellites: TeLEOS-2, the primary satellite, and Lumelite-4, the secondary satellite.
  • TeLEOS-2, which has a Synthetic Aperture Radar payload, was developed in collaboration between DSTA and ST Engineering to fulfil the satellite imagery needs of multiple Singapore agencies.
  • Lumelite-4 is a technology demonstration nano-satellite built by the Agency for Science, Technology, and Research’s Institute for Infocomm Research (I2R) and the National University of Singapore’s Satellite Technology and Research Centre (STAR). Its goal is to improve Singapore’s e-navigation maritime safety while also benefiting the worldwide shipping community.
  • The mission is PSLV’s 57th flight and the 16th using the PSLV Core Alone configuration (PSLV-CA).
  • The mission also involves in-orbit scientific experiments using the spent PS4 stage as an orbital platform, which is the third time that PS4 will be used after satellite separations as a platform for experiments. Non-separable payloads will be mounted on MSA (multi-satellite adapter), and the power will be provided to payloads and avionic packages based on their requirements.
