CMS-03

NEWS

• The Indian Space Research Organisation (ISRO) successfully launched its heaviest communication satellite, CMS-03, from Indian soil
• The launch took place from the Satish Dhawan Space Centre (SDSC), Sriharikota, Andhra Pradesh.
• The mission was executed by Launch Vehicle Mark-3 (LVM3-M5), popularly known as “Bahubali” due to its heavy-lift capability.

HIGHLIGHTS

• Launch Vehicle: LVM3-M5 (fifth operational mission of LVM3 series)
• Satellite: CMS-03
• Weight: 4,410 kg – the heaviest satellite ever launched from Indian soil.
• Orbit: Geosynchronous Transfer Orbit (GTO)
• Launch Time: 5:26 PM (IST)
• Duration: Satellite injected into orbit 16 minutes after liftoff at around 180 km altitude.
• Total Launch Count: 103rd mission from SDSC.

 Technical and Operational Significance

• Cryogenic Engine Innovation:
  • For the first time, ISRO reignited the thrust chamber of the cryogenic stage during flight — a major technological advancement.
• Payload Enhancement:
  • LVM3 was upgraded to enhance payload capacity by 10% to accommodate the heavier satellite.
• Precision Achievement:
  • ISRO Chairman V. Narayanan confirmed that CMS-03 was injected precisely within orbital specifications.

Purpose and Applications

• CMS-03 will operate in multiple frequency bands, providing wide communication coverage across the Indian landmass and adjoining oceanic regions.
• The satellite will replace the GSAT-7 series (launched in 2013) and provide services for at least 15 years.

Broader Importance

• Despite Cyclone Montha’s adverse weather, the launch succeeded flawlessly.
• CMS-03 stands as a symbol of India’s technological self-reliance and ISRO’s growing mastery in heavy-lift and cryogenic propulsion systems.
