Key Takeaways
- ISRO successfully launched Gsat-7R, India’s heaviest communication satellite at 4,410kg
- The satellite will significantly boost Indian Navy’s communication capabilities across the Indian Ocean Region
- Mission featured enhanced LVM3 rocket with 10% increased payload capacity
ISRO has successfully launched the Gsat-7R communication satellite, marking a significant milestone for India’s space capabilities and naval communications. The 4,410kg satellite – the heaviest ever launched from Indian soil – will provide the Indian Navy with enhanced telecommunication coverage across the strategic Indian Ocean Region.
Mission Details and Technical Achievements
The Gsat-7R was launched aboard the LVM3-M5 rocket from the Satish Dhawan Space Centre in Sriharikota. This mission represented the fifth operational flight of the LVM3 and featured a successful re-ignition of the cryogenic upper stage as an in-orbit experiment.
Approximately 16 minutes after lift-off, the rocket placed the satellite into a sub-Geosynchronous Transfer Orbit with a perigee of 26,700km. ISRO chairman V Narayanan confirmed that the vehicle’s performance was enhanced to increase its payload capacity by 10%.
Strategic Importance for Indian Navy
Gsat-7R is designed to replace the aging Gsat-7 (Rukmini), which was launched in 2013. The Navy emphasized that the satellite represents their determination to protect the nation’s maritime interests through advanced technology and self-reliance.
According to the Navy statement: “Gsat-7R will provide robust telecommunication coverage across IOR. Its payload includes transponders capable of supporting voice, data, and video links over multiple communication bands. This satellite will significantly enhance connectivity with high-capacity bandwidth, enabling seamless and secure communication links between ships, aircraft, submarines, and Maritime Operations Centres.”
Advanced Indigenous Technology
UR Rao Satellite Centre director M Sankaran revealed that the satellite carries advanced payloads in multiple frequency bands – UHF, S-band, C-band and Ku-band. The spacecraft incorporates several indigenous technologies including a 1,200-litre propulsion tank and collapsible antenna systems.
Sankaran confirmed: “All systems are functioning normally. The satellite is healthy, and all isolation valves have opened as expected.”
The Gsat-7R has an operational life of 15 years and marks a significant achievement for India’s space program, demonstrating the capability to launch heavier communication satellites domestically rather than relying on foreign launch vehicles.
