Credit: ISROA government communications satellite to link Indian citizens with telemedicine, education, and other services rocketed into orbit Thursday on an Indian Polar Satellite Launch Vehicle.
The CMS 1 satellite, formerly known as GSAT 12R, is on track to replace India’s GSAT 12 spacecraft in geostationary orbit providing telecom services across the Indian subcontinent and neighboring islands.
The roughly 1.5-ton satellite took off on the PSLV at 5:11 a.m. EST (1011 GMT) Thursday, or 3:41 p.m. local time in India. (...)
In the coming days, the Indian-built satellite’s own propulsion system will guide CMS 1 to its permanent operating orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. In geostationary orbit, the spacecraft will circle Earth at the same rate of the planet’s rotation, giving CMS 1 a continuous view of India.
The launch of India’s PSLV Thursday marked the second and final Indian space launch of 2020, following a months-long suspension of launch activity due to the COVID-19 pandemic. India resumed satellite launches last month with a PSLV mission that carried an Indian Earth-imaging satellite into orbit, plus several small commercial payloads for customers in the United States and Europe.
The satellite CMS 1 is replacing, GSAT 12, was launched in 2011 on a previous PSLV mission for a planned eight-year mission beaming telemedicine, remote education, weather forecasts and other public service information to rural communities.
The CMS 1 spacecraft, fitted with a C-band communications payload, will take over those duties. The satellite’s communications payload will reach users across the Indian mainland, the Andaman and Nicobar Islands, and the Lakshadweep Islands, according to the Indian Space Research Organization.
Thursday’s mission was the 52nd flight of a Polar Satellite Launch Vehicle, India’s workhorse rocket, since its debut in 1993.

The 44-meter-high Polar Satellite Launch Vehicle-C50 (PSLV-C50) lifted off from the Satish Dhawan Space Center on the Indian island of Sriharikota at 5:11 a.m. Eastern Dec. 17.
The CMS-01 communications satellite, the sole passenger, separated from the PSLV fourth stage 20 minutes later.
Once in geostationary orbit CMS-01 will provide extended C-band frequency communications for the Indian mainland and the Andaman-Nicobar and Lakshadweep islands. CMS-01 is expected to operate for more than seven years from 83 degrees East GEO with two deployable solar arrays providing 1500 W of power generation.
Indian Space Research Organisation (ISRO) chairman K Sivan stated after successful injection into GTO that CMS-01 would continue the work of GSAT-12, which launched July 2011.
The launch was the 77th from Satish Dhawan Space Center and the 52nd PSLV launch. The launcher was rolled out from the vertical integration facility to the pad Dec. 14 for final launch preparations.
The PSLV-XL upgraded variant used for the mission includes six, extended length side boosters. (...)
