"All 11 communication transponders (operating in UHF, S, C and Ku-bands) of India's advanced multiband communication satellite GSAT-7 have been successfully switched on and their performance is found to be normal," ISRO said in a statement.
The defence satellite GSAT-7 was successfully launched by European space consortium Arianespace's Ariane 5 rocket from Kourou spaceport in French Guiana last month.
"GSAT-7 is now positioned at its designated orbital slot of 74 deg East longitude in the geostationary orbit and In Orbit Testing (IOT) of the 11 transponders is in progress," it said.
Its payload is designed to provide communication capabilities to users over a wide oceanic region including the Indian land-mass.
