Indian Space Research Organisations (ISRO) Polar Satellite Launch Vehicle C55 (PSLV-C55) carrying Singapore’s TeLEOS-2 as the first satellite tv for pc and Lumelite-4 as a co-passenger satellite tv for pc took off from the Satish Dhawan Space Centre, Sriharikota, at 14.19 hours on April 22.

“Congratulations PSLV and NSIL for this successful launch,” stated ISRO Chairperson S. Somnath, whereas including that there are “interesting things” lined up within the close to future.

According to particulars supplied by ISRO, PSLV-C55 is a devoted industrial PSLV mission of NewSpace India Limited (NSIL), for a world satellite tv for pc buyer from Singapore.

ISRO launches the PSLV Orbital Experimental Module (POEM) PSLV-C55 mission with Singapore’s TeLEOS-2 as major satellite tv for pc and Lumilite-4 as a co-passenger satellite tv for pc perform in-orbit scientific experiments through the use of the spent PS4 successfully elevate off from the primary launch-pad Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh on April 22, 2023.

In this mission, TeLEOS-2 a Synthetic Aperture Radar satellite tv for pc would be the major satellite tv for pc and Lumelite-4 a know-how demonstration nano-satellite will probably be co-passenger satellite tv for pc. This is the 57th flight of PSLV and sixteenth mission utilizing the PSLV Core Alone configuration (PSLV-CA).

The TeLEOS-2 satellite tv for pc is developed below a partnership between DSTA (representing the Government of Singapore) and ST Engineering. Once deployed and operational, it is going to be used to help the satellite tv for pc imagery necessities of assorted companies inside the Government of Singapore. TeLEOS-2 carries a Synthetic Aperture Radar (SAR) payload. TeLEOS-2 will have the ability to present all-weather day and night time protection, and able to imaging at 1m full-polarimetric decision.

The LUMELITE-4 satellite tv for pc is co-developed by the Institute for Infocomm Research (I2R) of A*STAR and Satellite Technology and Research Centre (STAR) of the National University of Singapore. LUMELITE-4 is a complicated 12U satellite tv for pc developed for the technological demonstration of the High-Performance Space-borne VHF Data Exchange System (VDES). Using the VDES communication payload developed by I2R and STAR’s scalable satellite tv for pc bus platform, it goals to reinforce Singapore’s e-navigation maritime security and profit the worldwide transport neighborhood

PSLV-C55 mission will perform in-orbit scientific experiments through the use of the spent PS4 stage as an orbital platform.

This is the third time that PS4 will probably be used after satellite tv for pc separations as a platform for experiments. There will probably be non-separable payloads mounted on MSA (multi-satellite adapter). Payloads will probably be powered ON by a command in spite of everything satellites are separated. The platform could have a photo voltaic panel mounted across the PS4 tank which will probably be deployed after affirmation of the stage reaching stabilisation.

The deployment of the photo voltaic panels will probably be by way of a floor command. The platform will be certain that the deployed photo voltaic panel factors in the direction of the Sun optimally utilizing the suitable sun-pointing mode, which can enhance the facility technology functionality of the platform. The energy will probably be supplied to payloads and avionic packages based mostly on their necessities.

As part of POEM-2 (PSLV Orbital Experimental Module), there are seven experimental non-separable payloads: PiLOT (PSLV In orbitaL Obc and Thermals) OBC bundle from IIST; ARIS-2 (Advanced Retarding Potential analyser for Ionospheric Studies) experiment from IIST; HET based mostly ARKA200 Electric Propulsion System from Bellatrix; DSOD-3U and DSOD-6U deployer items together with DSOL-Transceiver in S- & X- bands from Dhruva Space; and Starberry Sense Payload from Indian Institute of Astrophysics (IAP).
