Indian Space Research Organisation (ISRO) will launch a communication satellite CMS-01, formerly named GSAT-12R, on December 17, using its Polar Satellite Launch Vehicle (PSLV) rocket’s XL variant numbered as PSLV-C50. The CMS-01 will be a replacement for GSAT-12 that weighed 1,410 kg and was launched on July 11, 2011, with a mission life of eight years.
CMS-01 is a communication satellite envisaged for providing services in Extended-C Band of the frequency spectrum, which will include the Indian mainland, Andaman and Nicobar and Lakshadweep Islands. The 42nd communication satellite of India, it will have a mission life of seven years.
- The 44-metre-high four staged/engine PSLV-C50 is the 22nd flight of PSLV in ‘XL’ configuration (with six strap-on motors hugging the first stage).
- The PSLV in the normal configuration is a four-stage/engine expendable rocket powered by solid and liquid fuels alternatively with six booster motors strapped on to the first stage to give higher thrust during the initial flight moments.
- The Indian space agency has PSLV variants with two and four strap-on motors, larger PSLV-XL and the Core Alone variant without any strap-on motors. The choice of the rocket to be used for a mission depends on the weight of the satellite and the orbit where the satellite has to be orbited.
