BHEL's Contribution to Heaviest Satellite Launch by ISRO

New Delhi: ISRO launched the heaviest multi band communication satellite CMS-03 on 2nd November 2025 from Indian soil. The Satellite weighing 4410 Kg, flew onboard a new generation home-grown LVM3-M5 rocket, enabling ISRO to achieve the rare feat. It will provide services over a wide oceanic region including the Indian landmass.

BHEL is proud to be associated with ISRO for this historic mission which is powered by BHEL manufactured three Space Grade Solar Panels and one Space Grade Li-ion battery. Each Panel of approx. 5.32 sq. m having 1.2 KW capacity each was manufactured at BHEL –Electronics Systems Division plant at Bangalore using multi junction solar cells.
