Inmarsat systems are built from the ground up as a commercial complement to government SATCOM networks

Enabling the flexibility, security and cost-efficiency that allows government users to complement their satellite systems, anytime, anywhere.

As a commercial satellite owner/operator for more than 40 years, Inmarsat has an unrivaled heritage of building, launching and operating a resilient global network encompassing a fleet of advanced multi-beam, multi-band satellites and robust ground infrastructure. Our history of commitment to safety services drives our global mobility-centric strategy, unique in the market – we cover the globe for land, sea and air services.

Built from the ground up

Inmarsat’s commercial satellite communication network was built from the ground up to complement the government’s communication network. This enables flexibility, security and cost-efficiency that allows government users to complement their satellite systems and access critical satellite connectivity when needed, without any upfront commitment. Inmarsat’s resilient, flexible and scalable capabilities in L-band/ELERA and Ka-band/Global Xpress and Military Ka-band are complementary to military satellite systems. We continue our investments in future next-generation capabilities with our visionary and fully funded technology roadmap which will see a further six satellites launch by 2025.

We offer a variety of space-based applications for launch support and space relay:

  • InRange: rapid, responsive and affordable launch telemetry from space, eliminating the need to construct and maintain costly ground-based launch infrastructure.
  • InCommand: establishing real-time connectivity for space relay in support of low and medium Earth orbit satellites via a highly efficient, cost-effective and time-critical solution for Low Earth Orbit (LEO) satellites.

A rich history of support

For decades the U.S. government has used our resilient, interoperable and scalable solutions to complement their military satellite communication systems. Through innovative ways and a variety of partnerships, Inmarsat Government offers solutions to architectural challenges and is responsive to government requirements. We have a proven track record of successfully integrating special government requirements to further enhance Inmarsat commercial spacecraft. By building the requirements into our design from the ground up, we are able to provide the government the full cost and schedule savings of a commercial program while reducing the integration risk present in a traditional government-furnished hosted payload model. This allows us to work closely with our customers to rapidly develop new capabilities or complement existing government military systems.

Innovations for the Next Frontier in Space Communications

ELERA worldwide L-band network from Inmarsat boosts performance and lowers cost of space operations by removing ground station, infrastructure dependencies.

Launch Support

Our InRange capability provides rapid, responsive and affordable launch telemetry from space, eliminating the need to construct and maintain costly ground-based launch infrastructure. InRange alleviates the requirement for a large network of downrange ground stations to maintain telemetry coverage and helps remove “black-out” phases that exist with terrestrial coverage of launches when switching between one ground station to the next.

Space Relay

Our InCommand solution enables commanding and telemetry on-demand for space assets operating below geostationary orbit. By establishing real-time connectivity for space relay in support of low and medium Earth orbit satellites, InCommand delivers a highly efficient, cost-effective and time-critical solution for any Low Earth Orbit (LEO) satellite by removing dependencies on ground infrastructure.
