CMS-01 Mission

CMS-01 is configured to provide communication services in the extended C-band frequency and its coverage will include the Indian mainland, the Andaman and Nicobar Islands, and the Lakshadweep Islands.

CMS-01 is expected to operate for more than seven years from 83 degrees East geostationary orbit with two deployable solar arrays providing 1,500 W of power generation.

India launched the CMS-01 extended C-band communications satellite into a geostationary transfer orbit on 2020-12-17.

Once in geostationary orbit, CMS-01 will provide extended C-band frequency communications for the Indian mainland and the Andaman-Nicobar and Lakshadweep islands.

Orbit raising maneuvers will be executed to position CMS-01 in geostationary orbit at its designated location.

After injection, CMS-01’s solar panels were automatically deployed and ISRO’s Master Control Facility at Hassan assumed control of the satellite.

CMS-01 was injected into an elliptical sub-Geosynchronous Transfer Orbit on 2020-12-17.

As of February 29, 2020, launch of GSAT-12R to replace GSAT-12 at 83°E was planned NET March 2020.

ISRO published a PSLV-C50 CMS-01 brochure on its website (https://www.isro.gov.in/pslv-c50-cms-01/pslv-c50-cms-01-brochure).

As of November 7, 2020, GSAT-12R was designated CMS-01 under ISRO's new naming system.
