India launched a military satellite from the Kourou spaceport in French Guiana on Friday morning.
The Indian Space Research Organisation said the satellite GSAT-7 will be placed in a geostationary orbit by next week and its transponders will be switched on.
The satellite is expected to boost the Indian Navy's surveillance abilities.
The launch was broadcast live on state television.
The BBC reports India has dozens of communication and weather satellites in orbit. It has also announced plans for an unmanned voyage to Mars.
