GSAT-7R (CMS-03) was successfully launched aboard the LVM3 (Launch Vehicle Mark-3) from the Satish Dhawan Space Centre, Sriharikota.

• LVM3 is India’s heaviest operational rocket for launching heavy communication satellites and deep-space missions. It is a three-stage vehicle, comprising 

• Solid Stage: Two solid strap-on boosters at first stage (use of solid propellant)
• Liquid State: One liquid core stage (liquid propellant) 
• Cryogenic Stage: One cryogenic upper stage (powered by the indigenous high-thrust CE-20 cryogenic engine, loaded with cryogenic propellant)

Key Features of GSAT-7R  Satellite

• It is a part of India’s advanced defence communication satellite series GSAT-7.
• Weight: ~4,400 kg
• Orbit: Launched into the Geosynchronous Transfer Orbit (GTO), it will eventually settle into Geostationary Orbit (35,786 kilometers above Earth).
• Coverage: Provides multi-band telecommunication services across the Indian Ocean Region and Indian landmass.
• Purpose: Strengthens space-based communication, maritime domain awareness, and secure links among Navy ships, submarines, aircraft, and Maritime Operations Centres.

Significance

• Indigenous development marks India’s growing self-reliance (Aatmanirbharta) in defence-space communication.
• Enhances Navy’s strategic capabilities and blue-water communication reach.
• Precision Warfare: Navigation satellites vital for missile accuracy and precision strikes.
