ISRO Communications Satellite CMS-01 will be launched on December 17

The communications satellite CMS-01, formerly named GSAT-12R, will count the XL variant of its polar satellite launch vehicle (PSLV) rocket as PSLV-C50 on the evening of December 17, the Indian space agency said on Friday. The PSLV-C50 rocket carrying the CMS-01 is scheduled to explode temporarily from the second launch pad at the rocket port at Sriharikota on December 17 at 3.41 pm, the Indian Space Research Organization (ISRO) said.

ISRO added that the release was subject to weather conditions.

CMS-01 is a communications satellite designed to provide services in the extended-C band of frequency spectrum, including the Indian mainland, the Andaman and Nicobar Islands and Lakshadweep Islands.

India’s 42nd communications satellite, with a mission life of seven years.

The 44-meter-high four-stage / engine PSLV-C50 is the PSLV’s 22nd aircraft in ‘XL’ configuration (six strap-on motors will hold the first stage).

By default, the PSLV is a four-stage / engine-powered rocket powered by solid and liquid fuels, with six booster motors built into the first stage to provide greater propulsion in the early flight moments.

The Indian Space Agency has PSLV variants with two and four strap-on motors, the larger PSLV-XL and the Core Alone variant.

The choice of rocket to be used for a mission depends on the weight of the satellite and the orbit of the satellite.

About 20 minutes into its flight, the PSLV-C50 CMS-01 will be ejected into Geosynchronous Transfer Orbit (GTO), and from there, the satellite will be taken into geo-synchronous orbit.

The CMS-01 will replace the 1,410 kg GSAD-12, which was launched on July 11, 2011 with an eight-year working life.

The PSLV-C50 rocket will be followed by the new small rocket launch vehicle (SSLV) EOS-02 (Earth observation satellite), and the geosynchronous satellite launch vehicle-F10 (GSLV). That is what ISRO Chairman Q. Carries EOS-3.

Other Indian satellites ready for launch are Jihad and Microsoft-2A.

The launch of the Jihad-1 satellite, scheduled for March 5 this year, was postponed due to technical reasons.

The GIZ-1 satellite will be carried by a GSLV rocket. The GSLV rocket was removed after the launch was stopped, and it is being refurbished. The rocket’s cryogenic engine is dropped and rebuilt.

The GSLV carrying the Jihad-1 is expected to fly after the PSLV C50.
