The new GX stations are located in Lino Lakes in Minnesota, USA; Winnipeg in Manitoba, Canada; and two sites near Auckland, New Zealand. Two further stations – in Fucino, Italy and Nemea, Greece – are already operational.
All six GX SAS will act as gateways between the broadband traffic routed via the Inmarsat-5 (I-5) satellites and terrestrial fixed networks.
The company says that the six SAS sites will deliver ground segment redundancy for GX services and support better reliability and availability, for example at times of adverse weather.
"This is an important milestone as we continue to move full speed ahead with the GX programme," said Rupert Pearce, CEO Inmarsat.
"Our satellite access station locations and capabilities are designed to support the requirements of Inmarsat’s government and commercial end-users. Government customers have been the first to deploy GX, taking advantage of the introduction of regional GX services through Inmarsat’s first Ka-band satellite – I-5 F1 – which serves Europe, Middle East, Africa and Asia."
"With many decades of serving the government and commercial markets, our end-users can trust that Inmarsat’s secure network infrastructure adheres to strict physical and Information Assurance (IA) standards, supported continuously by a dedicated cyber security team, to provide reliable assured access at all times, anywhere around the world."
Inmarsat has been providing commercial GX services in the Indian Ocean region since 1 July 2014. The company says that it hopes to launch the remaining two satellites for worldwide coverage early in 2015, with global commercial service introduction early in the second half of 2015.
