Kalamsat-V2 was a tiny student-built satellite from Space Kidz India that stayed attached to the fourth stage of PSLV-C44. It was the first payload to use the PSLV fourth stage as an orbital platform.
Re-entered Earth's atmosphere on 21 December 2023, according to the public satellite catalogue.
Kalamsat-V2 was an amateur radio communication payload developed by Space Kidz India. It tested low-cost electronics built from commercial off-the-shelf parts, including its on-board computer, power, communication and structure.
It was a 10 cm cube (a 1U CubeSat) weighing 1260 g. It never separated from the rocket's fourth stage (PS4).
PSLV-C44 lifted off from the First Launch Pad at Sriharikota at 23:37 IST on 24 January 2019. After releasing Microsat-R, the fourth stage restarted twice and climbed to a circular orbit of 443 km to act as a platform for experiments, with Kalamsat-V2 on board.
The public satellite catalogue tracks Kalamsat-V2 and the rocket stage as one object, which re-entered Earth's atmosphere on 21 December 2023.
