The Indian Space Research Organization (ISRO) is set to add two more satellites to its impressive tally of foreign satellite launches. On April 22nd, the Polar Satellite Launch Vehicle (PSLV) rocket’s core-only variant, code-named PSLV-C55, will take off from the Andhra Pradesh rocket port of Sriharikota, carrying two Singaporean earth observation satellites.
The first satellite, TeLEOS-2, weighs 741 kg, while the second, Lumilite-4, is a much lighter 16 kg. The PSLV-C55 will also include seven non-separable experimental payloads in its final stage or PS4.
ISRO uses the PS4 as an orbital platform for in-orbit experiments, which is called the PSLV Orbital Experimental Module (POEM). The payloads will be fueled after the two Singaporean satellites are isolated, and a solar panel will be installed on the platform around the PS4 tank.
The ground command will be used to set up the solar panels, ensuring they are ideally oriented towards the sun. The stage will guarantee that the conveyed sun-powered charger focuses towards the Sun utilizing the suitable sun-pointing mode, which will expand the power age capacity of the stage. According to the ISRO, payloads and avionics packages will receive power in accordance with their needs.
The launch of these two Singaporean satellites will increase the number of foreign satellites launched by ISRO to 424. The Indian space agency has been increasing its foreign satellite launches steadily, with 422 foreign satellites launched since the beginning of this year. In March, ISRO launched 36 OneWeb satellites, and it is expected that the number will continue to rise.
Conclusion
ISRO’s successful launch of foreign satellites has helped the country build a reputation as a reliable and cost-effective launch partner. The launch of the two Singaporean satellites on April 22nd is expected to further strengthen this reputation. The PSLV-C55 rocket’s ability to carry multiple payloads and provide an orbital platform for in-orbit experiments makes it an attractive option for foreign satellite launches. ISRO’s commitment to increasing its foreign satellite launches will also benefit the country’s economy, as it generates revenue and creates job opportunities in the space industry.
