Orbit GX30 MPT Demonstration System Completes Successfully On Inmarsat Global Xpress and Military Ka-band

GX is the world's first and only globally available, seamless mobile wideband service. In U.S. government service since July 2014, GX has established itself as the gold standard for reliable communication across land, sea, and air domains for assured mobile connectivity.

FREMONT, CA: Inmarsat Government, the leading provider of secure, global, mission-critical telecommunications to the U.S. government, Orbit Communications Systems Ltd., a leading provider of airborne communications solutions, and Boeing Commercial Satellite Services, announced that the Orbit GX30 multi-purpose terminal (MPT) demonstration system has successfully completed the first phase of testing with government users over Inmarsat Global Xpress (GX) and high-capacity, global military Ka-band. This follows the delivery of the Orbit GX46 MPT 46 cm antenna systems that have been in production since 2020.

Boeing's managed network service and secure commanding of the Inmarsat high-capacity, global military Ka-band (HCX) system provides U.S. government users with global "center of the beam" connectivity. Using hosted payloads on the Inmarsat 5 satellites, Boeing provides users 100-740 MHz of steerable, bi-directional spot beam capacity. This allows manual and closed-loop steering to always keep the designated user or platform in the center of the beam with the highest possible radiated power.

The GX30 terminal delivered a 126 Mbps+ forward link and a 29 Mbps+ return link. The MPT terminal is designed to maintain uninterrupted connectivity to the network during all flight phases.

GX30 is a modular, multi-role terminal that operates in both the GX commercial and military Ka-band utilizing a 30 cm antenna. The fully integrated three (3) Line Replaceable Unit (LRU) terminal consists of an RF antenna assembly (which includes all RF components), a Ka-band Power Supply Unit (KPSU), and a Modem Unit including Inmarsat's G-MODMAN for Global Xpress service and the Boeing WC5000 for Mil-Ka high throughput applications, making it one of the easiest to install and service tail-mount terminals available.

The GX30 groundbreaking compact terminal design has the lowest weight on the tail (less than 10 kg) and the lowest power consumption of any 30 cm terminal on the market today. It was developed for installation in a range of business jets, military aircraft, and unmanned aerial vehicles (UAVs). It complies with industry regulations and standards, including MIL-STD-188-164C, RTCA DO-160G, Federal Communications Commission (FCC), and European Telecommunications Standards Institute (ETSI).

The transmit performance of the terminal is best in class, and its lightweight, small footprint enables worldwide connectivity, supporting the full Ka frequency band. It has been built to be compatible with the Wideband Global SATCOM (WGS) system, thus making it an ideal choice for Intelligence, Surveillance, and Reconnaissance (ISR) missions. Furthermore, the terminal supports high return data link rates making it the optimal choice for users and missions, where sending large amounts of data from the aircraft is a critical aspect of the connectivity solution.

Daniel Eshchar, CEO of Orbit, said: "Orbit offers a complete range of airborne satellite communications terminals that maximize flexibility and enable future scalability. Built to fulfil the 'everywhere, all-the-time' coverage requirements of both the military and commercial airborne users, the GX30 MPT provides the best-in-class transmit performance under the harshest environmental conditions."
