There is an interesting thread on the ISRO sub-Reddit on the possibility of a bolted #quantum payload on the PS4 stage of the #PSLVC54.

The launch of the #PSLVC54 was so much more professional compared to the launch of the #VikramS of Skyroot.
All 9 satellites have separated from the #PSLVC54. Mission declared successful after PSLV performed a historic orbit lowering maneuver after deploying the primary satellite.
#PSLVC54 successfully deployed #EOS06 in its intended orbit at 742 km. Now, it will perform an orbit lowering maneuver to around 510 km to deploy the remaining 8 nanosatellites. Web stream returns at 12:45 pm for the same. Congratulations, #ISRO. Tense wait for other passenger payloads.
25 hour countdown to launch started at 10:56 am (IST). #PSLVC54 #EOS06

This launch vehicle will make an interesting manoeuvre. It first will launch Oceansat 3/EOS-06 in a 742 km orbit. It will then use Orbital Control Thruster (OCTs) to lower the orbit to launch the 8 'passenger payloads' into an orbit around 520 km.

ISRO to launch PSLV-C54 on November 26 at 11:46 am with Oceansat-3/EOS-06, 8 nano satellites: https://www.thehindu.com/sci-tech/science/isro-to-launch-pslv-c54-on-nov-26-with-oceansat-3-8-nano-satellites/article66160064.ece

8 satellites share the ride:
BhutanSat, for the Government of India
2 Indian private space company via NSIL, Pixxel Space's Anand and Dhruva Space's Thybolt-1 and Thybolt-2
4 foreign payloads built by the Swiss company Astrocast and launched via Spaceflight USA (via NSIL)
