Launch

Initially the satellite was planned to be launched in May 2018,[7][8] but was delayed after ISRO recalled it back to India from the launch site in French Guiana for additional checks weeks after ISRO lost communication to another communication satellite, the GSAT-6A, soon after its launch in March 2018.[9]

After the satellite was found fit for the launch, the new launch date had been set to 4 December 2018.[8][10] GSAT 11 was launched successfully from the European Spaceport, French Guiana (Guiana Space Center) on 2037 UTC, 4 December 2018 along with GEO-KOMPSAT-2A of KARI.[11][1]

Satellite

GSAT-11 was developed at the cost of Rs. 573.68 Crores and its launch was procured at cost of Rs. 810.94 Crores.[12][13][14] The payload consists of 40 high power Ku, Ka band transponders built at Space Applications Centre in Ahmedabad.[15]
