With reference to the POEM (PSLV Orbital Experimental Module), consider the following statements:

It will utilize the second and the third stage of a rocket as a stabilized platform to perform experiments.

It is carrying payloads from Indian space start-ups Digantara and Dhruva Space.

It has a dedicated Navigation Guidance and Control system.

Which of the statements given above is/are correct?

Question

POEM, the PSLV Orbital Experimental Module is a platform that will help perform in-orbit experiments using the final, and otherwise discarded, stage of ISRO’s workhorse rocket, the Polar Satellite Launch Vehicle (PSLV).
The PSLV is a four-stage rocket where the first three spent stages fall back into the ocean, and the final stage (PS4) after launching the satellite into orbit ends up as space junk.
However, in PSLV-C53 mission, the spent final stage will be utilised as a “stabilised platform” to perform experiments.
POEM is carrying six payloads, including two from Indian space start-ups Digantara and Dhruva Space.
POEM has a dedicated Navigation Guidance and Control (NGC) system for attitude stabilisation, which stands for controlling the orientation of any aerospace vehicle within permitted limits. The NGC will act as the platform’s brain to stabilize it with specified accuracy.
POEM will derive its power from solar panels mounted around the PS4 tank, and a Li-Ion battery. It will navigate using “four sun sensors, a magnetometer, gyros & NavIC”.
It carries dedicated control thrusters using Helium gas storage. It is enabled with a telecommand feature.
The Indian space agency first demonstrated the capability of using PS4 as an orbital platform in 2019 with the PSLV-C44 mission that injected Microsat-R and Kalamsat-V2 satellites into their designated orbits. The fourth stage in that mission was kept alive as an orbital platform for space-based experiments.
