Inmarsat says that the construction of the final four satellite access stations (SAS) for its Global Xpress (GX) I-5 fleet is now complete.

The GX high-speed broadband Ka-band network is scheduled for global commercial service introduction early in the second half of 2015.

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 three Inmarsat-5 (I-5) satellites and terrestrial fixed networks. Inmarsat says each SAS delivers full ground segment redundancy for GX services, delivering resiliency, reliability and availability.

This is useful, for example, at times of adverse weather.

Rupert Pearce, CEO Inmarsat, said: “This is an important milestone as we continue to move full speed ahead with the GX programme. Our satellite access station locations and capabilities are designed to support the requirements of Inmarsat’s government and commercial end-users.”

Inmarsat has been providing commercial GX services in the Indian Ocean region since 1 July 2014. The remaining satellites are set to launch early in 2015, on course to support global commercial service introduction early in the second half of 2015.
