Heavy cross winds delay GSAT-18 launch by a day

October 05, 2016 01:37 IST

The launch of India's latest communication satellite GSAT-18 onboard Arianespace rocket from Kourou in French Guiana has been deferred by a day due to heavy cross winds, Indian Space Research Organisation said.

"The launch has been postponed by one day due to heavy cross winds," a senior ISRO official said late Tuesday night.

Arianespace launch vehicle Ariane-5 VA-231, carrying GSAT-18 along with co-passenger Sky Muster II for the Australian operator nbn (National Broadband Network) was scheduled for launch at 2am on Wednesday.

"Due to high altitude winds, decision to postpone #VA231. Tomorrow's forecast is green. Launch window now set to open on Oct 5 at 20:30 UTC," Arianespace CEO Stéphane Israël tweeted.

The launch has been scheduled now between 2.00am and 3.15am India time on October 6, it said, adding "The launcher, with its Sky Muster II and GSAT-18 satellite payloads, remains in a safe standby condition."

GSAT-18 is designed to provide continuity of services on operational satellites in C-band, Extended C-band and Ku-bands.

Weighing 3,404 kg at lift-off, the satellite carries 48 communication transponders to provide services in Normal C-band, Upper Extended C-band and Ku-bands of the frequency spectrum. It also carries Ku-band beacon to help in accurately pointing ground antennas towards the satellite.

GSAT-18 will be launched into a Geosynchronous Transfer Orbit.

GSAT-18's co-passenger Sky Muster II, built by SSL (Space Systems Loral) in Palo Alto, California, is aimed at bridging the digital divide, especially in the rural and isolated regions of Australia.
