Launch
editPrior to launch, the spacecraft was transported from India to Cayenne – Rochambeau Airport in French Guiana by an Antonov An-124 cargo aircraft. The success of the launch is said to have made up for the previous loss of two satellites on the indigenous GSLV rocket.[4][5] GSAT-8 was co-located with INSAT-3E at 55°E.
