NOB-Sullurpet news: The Indian Space Research Organization (ISRO) has achieved another rare feat. It has successfully launched the 4,410 kg communication satellite CMS-03 into the designated orbit. The satellite was sent into space by the Launch Vehicle Mark 3 (LVM3-M5) Bahubali rocket from the second launch pad at the Satish Dhawan Space Center-Shar in Sriharikota, Tirupati district. The countdown began at 5.26 pm on 01.11.2025, and exactly 24 hours later at 5.26 pm on 02.11.2025, the rocket burst into flames and shot into space. CMS-03 has set a record as the heaviest communication satellite launched by ISRO so far. The satellite was successfully placed into an elliptical geosynchronous transfer orbit (GEO) at an altitude of 29,970 km from the Earth (apogee) and 170 km from the Earth (perigee). ISRO announced that the satellite control center in Hassan near Bengaluru received signals that the CMS-03 satellite had reached orbit and that its solar panels had been deployed. Scientists at the Satellite Control Center will burn the fuel in the CMS-03 satellite in four to five stages and launch it from the Geo Transfer Orbit to the Geo Orbit (geostationary orbit) at an altitude of 36,000 kilometers above the Earth. From there, the satellite services will be available. ISRO scientists expressed joy over the success of the LVM3, known as the Bahubali rocket, for the eighth consecutive time. The LVM3 rocket has cemented ISRO’s reputation worldwide. The LVM3-M5 rocket is a three-stage launch vehicle. It has two solid motor strapons (S200), a liquid propellant core stage (L110), and a cryogenic stage (C25). It is a rocket developed with indigenous knowledge.
Multi-band communication satellite
CMS-03 is unique among the communication satellites launched by ISRO. It is a part of the GSAT series. CMS-03 is the GSAT-7R satellite that will be launched in its place after the GSAT-7 satellite launched in 2013 has completed its service life. It is the heaviest among the communication satellites. It is noteworthy that this is the first time in the history of ISRO to launch a communication satellite weighing 4,410 kg. Usually, communication satellites are between 2,000 kg and 3,500 kg. CMS-03 has been launched with multi-band transponders as payloads. It will serve a wide ocean area including the Indian territory at all times. It will provide sharp connectivity to civil strategic and maritime users. CMS-03 has been designed in accordance with the current changing technology. This satellite will provide better services, especially in internet connectivity and DTH broadcasting. It will be possible to know the sea weather conditions at any time. CMS-03 was designed for the Indian Navy. Scientists said that it will work for at least 15 years.
ISRO’s status in the world has increased: K. Narayanan
After the success of the LVM3-M5 launch, ISRO scientists congratulated each other at the Mission Control Center. ISRO Chairman K. Narayanan spoke on the occasion. He said that all the stages of the rocket worked wonderfully. He said that ISRO’s reputation in the world has increased further with this success. He commented that the success of LVM3-M5 is historic and a matter of pride for ISRO. He emphasized that this is a symbol of self-reliant India. He said that along with the launch of two PSLV rockets this year, they are going to launch the American Bluebird satellite using an LVM3-M6 rocket.
