The Indian Space Research Organisation (ISRO) launched two Singapore satellites aboard a polar satellite launch vehicle (PSLV) from the Satish Dhawan Space Centre in Sriharikota on Saturday.

The PSLV-C55 mission is a dedicated commercial mission operated by NSIL, with TeLEOS-2 serving as the principal satellite and Lumelite-4 serving as a co-passenger satellite. The TeLEOS-2 is a synthetic aperture radar satellite developed for the Singapore government by the Defence Science and Technology Agency (DSTA) and ST Engineering.


It has a Synthetic Aperture Radar (SAR) payload capable of imaging at 1 metre complete polarimetric resolution for Singapore and enabling all-weather day and night coverage. Lumelite-4 is an advanced 12U satellite created by the National University of Singapore’s Institute for Infocomm Research and Satellite Technology and Research Centre for the technology demonstration of the High-Performance Space-borne VHF data Exchange System (VDES).

In addition to launching the two satellites, ISRO scientists intend to conduct an in-orbit scientific experiment using the spent PS4-stage as an orbital platform through the PSLV Orbital Experimental Module (POEM)2 during this mission.

ISRO, Bellatrix, Dhruva Space, and the Indian Institute of Astrophysics will all have payloads on the POEM-2 platform. After the primary and co-passenger satellites are separated, scientists will power these payloads. The platform will incorporate a solar panel facing the Sun to boost its power-generating potential, supplying power to payloads and avionic packages as needed.

Saturday’s mission would be PSLV’s 57th flight and the 16th using the PSLV Core Alone configuration.

ISRO successfully launched the TeLEOS-1 satellite into a 550 km circular orbit in December 2015 as part of the PSLV-C29 mission, together with five other Singapore satellites.
