December 16, 2021 – Inmarsat ORCHESTRA, the future network for global mobility and government communications, has achieved its first milestone in space with the successful activation of a low Earth orbit (LEO) satellite payload. The LEO satellite is testing new concepts and system configurations for ORCHESTRA’s proposed LEO constellation, which will seamlessly integrate with geosynchronous orbit (GEO) and highly elliptical orbit (HEO) satellites, and a terrestrial 5G network, to deliver a uniquely powerful global communications solution for mobility and government customers. ORCHESTRA is the first global network of its kind; creating a global, multi-dimensional, dynamic mesh network that will redefine connectivity at scale with the highest capacity for mobility worldwide and at hot spots across the world. It will deliver the fastest average speeds and the lowest average latency of any network, planned or in existence. While details of the in-orbit testing remain confidential, Inmarsat has confirmed that the LEO demonstration satellite payload is testing concepts for LEO-to-ground and LEO-to-GEO communications, which are key steps in delivering the unique capabilities proposed for ORCHESTRA. As the LEO satellite features a reprogrammable payload, additional concepts will be tested over the coming months.
