Global Xpress

The system includes the space segment and ground segment to provide geo-visible earth connectivity. The space segment provides two primary communications payloads for servicing users: the Global Service Beam (GSB) Payload and the High Capacity Payload (HCP). The ground segment provides SASs and a multiprotocol label switching (MPLS) infrastructure that interconnects all Inmarsat L-band and Ka-band resources. The ground segment also provides secure enclaves for supporting Customer-specific equipment and services. Management and status of all interfaces is accomplished through available Web-Based User Interface (WebUI) and machine-to-machine (M2M) interfaces.

Global Xpress meets critical Information Assurance requirements to include US Department of Defense Instruction (DoDI) 8500.2, National Institute of Standards and Technology (NIST) Special Publication (SP) 800-53, and the International Organization for Standardization / International Electrotechnical Commission (ISO/IEC) 27000 Information Security Management Systems (ISMS) standards. To provide even greater levels of assurance, GX Satellite Access Stations (SASs) are located in NATO and “Five Eyes” countries (Australia, Canada, New Zealand, the United Kingdom and the United States).

In May 2017, Inmarsat and Thales executed a series of tests that successfully demonstrated communications using Thales’ System 21 on Inmarsat’s Global Xpress (GX) high-capacity steerable antennas. These tests illustrate the ability of Thales’s System 21 modem to support resilient, protected and secure, high-data-rate connectivity for mission-critical military and government users.

Recent over-the-air tests, held in January 2017, were conducted by Inmarsat with VT iDirect using iDirect’s next-generation DVB-S2X technology. During the tests, Inmarsat achieved a forward channel throughput rate of 330 Mbps over a live Inmarsat GX satellite in orbit.

Inmarsat is providing its Global Xpress (GX) satellite service to the Australian Border Force. Eight maritime vessels have early in 2017 been fitted with new Cobra-class satellite communications terminals.

The U.S. Department of Defense (DOD) has awarded Comsat a contract to support communication activities on the African continent with Inmarsat’s Global Xpress Satcom as a Service capability.
