PSLV-C55
The PSLV-C55 was the 57th mission of Indian Space Research Organisation's Polar Satellite Launch Vehicle and the 16th flight of the PSLV-CA variant. It successfully delivered the TeLEOS-2 and Lumelite-4 payloads to their intended orbits.
Mission overview
The mission was a dedicated commerlaunch through NSIL with TeLEOS-2 as primary satellite and Lumelite-4 as a co-passenger satellite weighing 741 kg and 16 kg respectively. Both satellites belong to Singapore.This also marks the third time that PS4 is used after satellite separations as a platform for experiments. There are non-separable payloads mounted on MSA. Payloads are powered on by a command after all satellites are separated. The orbital platform will remain in the same orbit achieved at the end of PS4 tank passivation after the primary mission. It has an expected life of 1 month.
As a part of POEM-2, there are seven experimental non-separable payloads:
- PiLOT OBC package from IIST
- OBC package from IIST
- ARIS-2 experiment from IIST
- HET based ARKA200 Electric Propulsion System from Bellatrix Aerospace
- DSOD-3U and DSOD-6U deployer units along with DSOL-Transceiver in S- & X- bands from Dhruva Space
- Starberry Sense Payload from Indian Institute of Astrophysics
