ISRO to Launch Heaviest Communication Satellite CMS-03 Today

The launch will take place at 17:26 from the second launch pad of Satish Dhawan Space Station in Sriharikota. The event will be broadcast live on ISRO’s YouTube channel.

The satellite will strengthen the Navy’s space-based communications and maritime domain awareness capabilities with a variety of indigenous, state-of-the-art components developed specifically to meet the operational requirements of the Indian Navy.

“This satellite is India’s heaviest communications satellite to date, weighing approximately over 4,400 kg, and includes many indigenous, state-of-the-art components developed specifically to meet the operational requirements of the Indian Navy,” the Indian Navy said.

According to ISRO, CMS-03 is a multi-band communications satellite that will provide services over a wide oceanic region, including the Indian landmass.

The satellite will be launched by the LVM3 launch vehicle, which successfully carried India’s Chandrayaan-3 mission to the Moon’s south pole. This will be the vehicle’s fifth operational flight.

“Weighing around 4,400 kg, CMS-03 will be the heaviest communications satellite to be launched into Geosynchronous Transfer Orbit (GTO) from Indian territory. The previous mission of LVM3 launched the Chandrayaan-3 mission, in which India became the first country to successfully land near the south pole of the moon,” ISRO said in a statement. he said.

The launch vehicle was previously assembled and had been on the launch pad since October 26 for pre-launch operations.

The launch of LVM3-M5 will consist of eight sequences in which CMS-03 will separate from the vehicle at an altitude of approximately 179 kilometers and a speed of approximately 10 kilometers per second.

The height of the launch vehicle is 43.5 meters and the total take-off mass is 642 tons. It uses three stages of propellant to enable the satellite to reach Geosynchronous Transfer Orbit (GTO).
