Indian To Launch 2,535 kg Satellite Onboard European Launch Vehicle

Bengaluru: India will launch its latest communication satellite onboard European launch services provider Arianespace’s launch vehicle on February 6 from French Guiana, Indian Space Research Organisation said Friday.

According to Arianespace, the launch of Ariane-5 (VA 247) is scheduled for 2:31 am India time on Wednesday.

Weighing about 2,535 kg, the Indian satellite, GSAT-31, will provide continuity to operational services on some of the in-orbit satellites, ISRO said. 

The satellite derives its heritage from ISROs earlier INSAT/GSAT satellite series, the space agency said, adding that it provides Indian mainland and island coverage. 

GSAT-31 is the country’s 40th communication satellite which is configured on ISRO”s enhanced ”I-2K Bus”, utilising the maximum “bus capabilities” of this type. 

This satellite will augment the Ku-band transponder capacity in Geostationary Orbit, ISRO said.

With a mission life of around 15 years, GSAT-31 will be used for supporting VSAT networks, Television uplinks, Digital Satellite News Gathering, DTH-television services, cellular backhaul connectivity and many such applications. 

It also provides wide beam coverage to facilitate communication over large oceanic region, comprising large parts of Arabian Sea, Bay of Bengal and Indian Ocean, using a wide band transponder. 

According to ISRO, two Ku-band beacon downlink signals are transmitted for ground tracking purpose.

Saudi Geostationary Satellite 1/Hellas Sat 4 will be the co-passenger of GSAT-31 during the launch, Arianespace said.

Comprising two payloads, Saudi Geostationary Satellite 1/Hellas Sat 4, also called HS- 4/SGS-1, is a geostationary condosat for KACST (King Abdulaziz City for Science and Technology Saudi Arabia) and Hellas Sat (Greece Cyprus). 

It will provide telecommunication capabilities, including television, Internet, telephone and secure communications in the Middle East, South Africa and Europe, Arianespace said on its website.

GSAT-30 is another geostationary satellite to be lofted soon by Arianespace.

Since the launch of Indias APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 22 satellites and signed 24 launch contracts with the Indian space agency, it said.
