ISRO planning for a six-tonne ‘K’ band satellite

ISRO is planning to build/import six-tonne ‘K’band satellite.


  • The K band will allow higher and faster data transmission on the Internet by at least 2-3 times what ISRO satellites offer at present
  • It will suit VSAT operators who support this traffic.
  • K band transponder can accommodate far more users more efficiently than ISRO’s older Ku band satellites.


  • ISRO sent up GSAT-4 with a K band transponder. However, its homegrown GSLV launcher failed.
  • ISRO also built a K-band satellite, called HYLAS-1 (or Highly Advanced Satellite) for a fee for British operator Avanti in a tie-up with Europe’s Astrium.
