Transcription

Satellite

GSAT-12 was considered to be a replacement of the aged satellite INSAT-3B. It provided services like tele-education, tele-medicine, disaster management support and satellite internet access.[4]

Payloads

GSAT-12 was equipped with 12 Extended C-band transponders.

Launch

GSAT-12 was launched onboard PSLV-XL C17 from second launch pad of Satish Dhawan Space Centre on July 15, 2011.[5] The tentative life of satellite was 8 years.[6][7]

Replacement and relocation

While GSAT-12 was still operational a replacement satellite CMS-01(formerly GSAT-12R) was launched on 17 December 2020.[8] GSAT-12 was relocated from 83°E slot to 48°E slot on 19 March 2021.[9]

End of mission

In March 2023 GSAT-12 was retired from its operational service. After seven maneuvers to raise the satellite to a circular graveyard orbit, 390 km above GEO belt.[10][11][12]
