Launch Date

GSAT-14 is the twenty third geostationary communication satellite of India built by ISRO. The main objectives of GSAT-14 mission are: i) To augment the In-orbit capacity of Extended C and Ku-band transponders ii) To provide a platform for new experiments.

The payloads of GSAT-14 are:
  • Six extended C-band transponders for Indian mainland and island coverage with 36 dBW Edge Of Coverage- Effective Isotropic Radiated Power (EOC-EIRP)
  • Six Ku-band transponders covering the mainland India with 51.5 dBW EOC-EIRP
  • Two Ka-band Beacons operating at 20.2 GHz and 30.5 GHz to carry out attenuation studies
Some of the new technologies being tested on GSAT-14 are:
  • Fiber Optic Gyro
  • Active Pixel Sun Sensor
  • Ka band beacon propagation studies
  • Thermal control coating experiments
