The satellite would enhance the Navy's space-based communications and maritime domain awareness capabilities with indigenous, state-of-the-art components developed specifically to meet the Indian Navy's operational requirements.
"This satellite is India's heaviest communication satellite to date, weighing approximately more than 4,400 kg, and includes many indigenous state-of-the-art components developed specifically to meet the Indian Navy's operational requirements," the Indian Navy said.
CMS-03 is a multi-band communication satellite that will provide services over a wide oceanic region, including the Indian landmass, according to ISRO.
The satellite will be launched by the famous LVM3 launch vehicle, which successfully landed India on the lunar South Pole in the Chandrayaan-3 mission. This will be the vehicle's fifth operational flight."CMS-03, weighing about 4400kg, will be the heaviest communication satellite to be launched to Geosynchronous Transfer Orbit (GTO) from Indian soil. The previous mission of LVM3 launched the Chandrayaan-3 mission, in which India became the first country to land successfully near the lunar south pole," ISRO said in a statement.
