New Delhi: In a historic achievement, the Indian Space Research Organisation (ISRO) successfully launched the heaviest multi-band communication satellite, CMS-03, on 2nd November 2025 from Indian soil. Weighing 4,410 kg, the satellite was deployed aboard the new-generation LVM3-M5 rocket, marking a significant milestone in India’s space program. CMS-03 is expected to provide communication services across a vast oceanic region as well as the Indian landmass.
BHEL’s Crucial Contribution to India’s Space Success
Bharat Heavy Electricals Limited (BHEL), a leading Indian public sector undertaking, played a pivotal role in powering the CMS-03 satellite. The satellite’s energy requirements were met by three BHEL-manufactured space-grade solar panels and a space-grade Li-ion battery. Each solar panel, measuring approximately 5.32 sq. m with 1.2 kW capacity, was manufactured at BHEL’s Electronics Systems Division plant in Bangalore using advanced multi-junction solar cells.
The satellite was also powered by a single Li-ion battery of 11 kWh capacity, manufactured and rigorously tested at the same facility. In addition, 110 BHEL-made Li-ion cells were integrated into the LVM3-M5 launch vehicle, contributing to the successful placement of CMS-03 into orbit.
Continuing a Legacy of Space-Grade Innovation
Following its earlier successes with Chandrayaan-3, SPADEX, and NISAR missions, all powered by BHEL solar panels and batteries, this “Bahubali mission” highlights the strength and reliability of India’s indigenous manufacturing capabilities. It underscores BHEL’s continued role in supporting ISRO’s ambitious programs and India’s growing contribution to global space science and exploration.
Showcasing India’s Technological Prowess
This launch not only demonstrates ISRO’s advanced launch capabilities but also reflects the synergy between India’s research organizations and public sector undertakings like BHEL. The mission strengthens India’s position on the global space map and signals the country’s ability to achieve high-value technological milestones through homegrown innovation.
As CMS-03 begins its operational journey, it is expected to enhance communication coverage across India and surrounding oceanic regions, supporting applications in defense, disaster management, and telecommunication services, while reiterating India’s growing footprint in the global space arena.
