Satellite scheduled to launch from Kourou in French Guiana
In a statement, ISRO said the satellite, weighing about 2,535 kg, is scheduled for launch onboard the Ariane-5 (VA247) from Kourou in French Guiana.
"The satellite GSAT-31 is configured on ISRO's enhanced I-2K Bus, utilizing the maximum bus capabilities of this type," the agency said.
It further said, "The satellite derives its heritage from ISRO's earlier INSAT/GSAT satellite series."
GSAT-31 will support VSAT networks, TV uplinks, DTH TV services
ISRO said that the satellite provides "Indian mainland and island coverage." It also said the 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.
Satellite will cover Arabian Sea, Bay of Bengal, Indian Ocean
The satellite will also provide wide beam coverage to facilitate communication over a large oceanic region comprising a large part of the Arabian Sea, the Bay of Bengal and the Indian Ocean using the wideband transponder, ISRO said.
The agency added that two Ku-band beacon downlink signals are transmitted for ground tracking purpose.
The downlink in Ku-band is primarily used for satellite television.
