Recently, ISRO launched India’s 42nd Communication satellite CMS-01
About Communication satellite CMS -01
- It is envisaged to provide services in the Extended-C Band of the frequency spectrum whose coverage will include the Indian mainland, Andaman-Nicobar and Lakshadweep Islands
- CMS-01 is the country’s 42nd communication satellite and will have a mission life of seven years.
- The satellite will be the first in a new series of communication satellites by India after the GSAT and INSAT series.
- The new satellite would replace the GSAT-12 in orbit, which was launched in 2011.
- CMS-01 was launched with PSLV C50 and It will be the 52nd mission for India’s Polar Satellite Launch Vehicle (PSLV).
- 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 CMS-01 is also the first in a new series of communication satellites by India, following the INSAT and the GSAT series. The last satellite launched by ISRO was called Earth Observation Satellite (EOS) 01
|About PSLV launch vehicle|
- Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages.
- After its first successful launch in October 1994, PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 39 consecutively successful missions by June 2017.
- During 1994-2017 period, the vehicle has launched 48 Indian satellites and 209 satellites for customers from abroad.
- Besides, the vehicle successfully launched two spacecraft – Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013 – that later traveled to Moon and Mars respectively
- The PSLV in normal configuration is a four-stage expandable 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.
- ISRO 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 rocket to be used for a mission depends on the satellite’s weight and the orbit in which it is to be positioned.
