PSLV-C55 lifted off in its Core Alone configuration from Satish Dhawan Space Center (SDSC), Sriharikota at 1419 hrs (IST) on 22 April 2023. The primary mission of the launch was a commercial flight for Singapore’s TeLEOS-2.

TeLEOS-2 is the first synthetic aperture radar (SAR) Earth observation satellite built by Singapore indigenously. It carried a secondary payload from Singapore, LUMELITE-4. This was a “12U satellite developed for the technological demonstration of the High-Performance Space-borne VHF Data Exchange System (VDES)”. This aimed to improve maritime safety.

Of significance for India, were payloads developed by non-governmental entities (NGEs) and academia. These were payloads fixed to the fourth stage of the PSLV (PS-4). After deployment of the primary and secondary satellites from Singapore, the PS-4 would become the PSLV Orbital Experimental Module (POEM-2).

  3. HET (Hall Effect Thruster) based ARKA200 Electric Propulsion System from Bellatrix Aerospace

  4. DSOD-3U and DSOD-6U deployer units along with DSOL-Transceiver in S- & X- bands from Dhruva Space

  5. Starberry Sense Payload from Indian Institute of Astrophysics (IIAP).
