From UPSC perspective, the following things are important :

Prelims level : CMS-01

Mains level : Not Much

The Indian Space Research Organisation (ISRO) successfully placed into a transfer orbit India’s 42nd communications satellite, CMS-01, carried onboard the PSLV-C50.

CMS-01

  • It is a communications satellite envisaged for providing services in extended C Band of the frequency spectrum and its coverage will include the Indian mainland and the Andaman & Nicobar and Lakshadweep islands, the ISRO.
  • The satellite is expected to have a life of over seven years.
  • It was injected precisely into its pre-defined sub- geostationary transfer orbit (GTO).
  • CMS-01 is considered to be a replacement of the aged satellite GSAT-12. It provides services like tele-education, tele-medicine, disaster management support and Satellite Internet access.

What is GTO?

  • A geosynchronous transfer orbit or geostationary transfer orbit (GTO) is a type of geocentric orbit.
  • Satellites which are destined for geosynchronous (GSO) or geostationary orbit (GEO) are (almost) always put into a GTO as an intermediate step for reaching their final orbit.
  • A GTO is highly elliptic.
  • Its perigee (closest point to Earth) is typically as high as low Earth orbit (LEO), while its apogee (furthest point from Earth) is as high as geostationary (or equally, a geosynchronous) orbit.
