November 3, 2021 – Intelsat, operator of the world’s largest integrated satellite and terrestrial network, OneWeb (OWT), a global provider of innovative, secure satellite communications, and Linchpin Solutions, a leader in C5ISR systems and programs, successfully demonstrated a multi-orbit satellite communications solution for representatives of the U.S. Army and Department of Defense (DoD). This is a strategic demonstration to the U.S. DoD that shows transport diversification between the geostationary orbit (GEO) and low Earth orbit (LEO) constellations with seamless switching between them. Referred to as Automated Primary, Alternate, Contingency, and Emergency (APACE) communications, the solution enables soldiers to survive and excel in contested electronic warfare environments. The reliability of communications is significantly improved by simultaneously sending data over multiple paths and adjusting the traffic flow in real-time between GEO and LEO satellite constellations. Intelsat and OWT used both GEO and LEO services simultaneously, switching the data flow between orbits instantly at the packet level, using software to determine which connection will provide the best experience based on the technical requirements of the end service. The software solution can be hosted on existing fielded ruggedized virtual machine platforms allowing the system to run in the harshest environments. Two satellite links were established during the demo – one on the Intelsat 37 (IS-37) satellite and one on a OneWeb satellite. The links communicated through various end-user terminals, including a SatCube terminal, a Kymeta U7/8 terminal, a Litecom GEO terminal, and a OneWeb Intellian terminal, demonstrating applications such as two-way voice and data downloads and MP4 video.
