The U.S. Government is weighing options for the development of a hybrid, space-based satellite communications (SATCOM) architecture, which includes multi-orbit, multi-band networks, to support its resilience and flexibility requirements. Meanwhile, the commercial industry is continuing to innovate and is preparing to deliver massive amounts of SATCOM capacity, flexibly and data security worldwide while providing the reliability and availability that is critical to achieving mission success.

Inmarsat Government, a Viasat business, has a long-time heritage of developing, deploying and fully managing multi-band solutions that meet our U.S. Government customers’ unique mission requirements. We envision an integrated and secure space, air and ground communications architecture supporting multi-service operations globally along with an Enterprise Network Management system for situational awareness and control.

Our SATCOM as a Managed Service (SaaMS) approach has emerged as the satellite acquisition model for the modern age. Designed for global mobility, it provides a critical end-to-end communications infrastructure that includes the space and ground segment elements, security controls as well as type-approved terminals. It equals speed and flexibility in multiple bands allowing users to rapidly tailor and scale solid solutions for any platform in an uncertain battlefield. It delivers seamless user experience while saving government resources.

We see multi-orbit and multi-dimensional networks as an important factor in meeting future demand. Our roadmap is already well aligned with the Hybrid Space Architecture vision. Today, we provide global, multi-band, spacecraft diverse, operational capability from a constrained need in and around a Department of Defense target area up to very high bandwidth needs associated with a division level Tactical Operations Center (TOC).

Specifically, we offer a strong multi-band Primary, Alternate, Contingency and Emergency (PACE) plan to help build resilient communications worldwide. Our capabilities will only grow with the addition of our ORCHESTRA dynamic mesh network which combines elements of Geostationary Earth Orbit (GEO), Highly Elliptical Orbit (HEO), and Low Earth Orbit (LEO) SATCOM services and 5G terrestrial connectivity to support PACE as well as aggregated network services. As we expand, we remain firmly committed to delivering robust, seamless global communications with assured Service Level Agreements and Committed Information Rates – the guaranteed minimum throughput rate.

Below are examples of our multi-orbit, multi-band capabilities :

  • Our ORCHESTRA is designed to incorporate new, hyper-intelligent software-defined wide area network (SD-WAN) technology, which would enable intelligent orchestration and tie Inmarsat’s existing services together, enabling our customers to dynamically build and manage their aggregation and PACE plans and associated operational network configurations based on ever-changing mission requirements.
  • We provide modem manager technology that enables interoperability between systems/switching between multi-band systems. Our G-MODMAN Open Platform (OP) modem enables government access to multiple modems and services as needed.

Our multi-orbit, multi-band capabilities help U.S. Government customers thrive with highly resilient communications to meet their critically important mission requirements, even in contested, degraded and operationally limited environments. Wherever they are headed, they go in confidence that our seamless SATCOM connectivity will be there for them.
