New Delhi: India’s latest communication satellite GSAT-15 was successfully placed in orbit by an Ariane 5 launcher of Arianespace from the European spaceport at Kourou in French Guiana in the wee hours of Wednesday.

The satellite, built by the Indian Space Research Organisation (ISRO) and designed to deliver telecommunications services as well as dedicated navigation aid and emergency services for India, was launched on board Ariane 5 flight VA 227 at 0304 hours IST on Wednesday (1834 hours local time on Tuesday in French Guiana).

Flight VA 227 lifted off with a pair of telecommunications satellites: GSAT-15 and Arabsat-6B (Badr-7) in near perfect conditions with a tota lift performance of approximately 9,810 kg. The two satellites were deployed during a flight lasting 43 minutes.

“I’m happy to announce another Ariane5 success! Our on-board telemetry system confirms both payloads separated as planned,” Mr. Stéphane Israël, Arianespace Chairman & CEO, said.

GSAT-15 is a high power satellite that will be inducted into India’s INSAT/GSAT system, ISRO sources said. Weighing 3164 kg at lift-off, GSAT-15 carries a total of 24 communication transponders in Ku-band as well as a GPS Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands.

GSAT-15 is the third satellite to carry GAGAN payload after GSAT-8 and GSAT-10, which are already providing navigation services from orbit. GSAT-15 carries a Ku-band beacon as well to help in accurately pointing ground antennas towards the satellite.

The INSAT system, established in 1983, is one of the largest domestic communication satellite systems in the Asia Pacific Region. It presently comprises 12 satellites, providing transponders in S, C, Extended-C and Ku-bands.
