Inmarsat unveils new communications network

Inmarsat has unveiled plans for its new communications network, ORCHESTRA.

Inmarsat ORCHESTRA aims to bring together existing geosynchronous (GEO) satellites with low earth orbit satellites (LEO) and terrestrial 5G into an integrated, high-performance solution.

Whether for a ship in port, an aircraft preparing to land, or a defence force deployed in a remote location, ORCHESTRA is designed to meet evolving connectivity needs in the mobility market with a service unmatched by any competitor offering, planned or in existence, says Inmarsat.

“An orchestra brings different instruments together, each supporting the other and playing its role in the masterpiece. We’re building ORCHESTRA on the same concept,” says Rajeev Suri, CEO of Inmarsat.

“By combining the distinct qualities of GEO, LEO and 5G into a single network, we will deliver a service that is far greater than the sum of its parts. Our customers will benefit from dramatically expanded high throughput services around the world. This is the future of connectivity and Inmarsat is perfectly positioned to bring it to the world with its proven technology expertise, right base of customers and partners, and financial strength.”

New services include close-shore navigation for autonomous vessels, emergency safety services for maritime crews, secure and tactical private networks for governments and direct-to-cloud connections for airlines. New segments set to benefit from ORCHESTRA include energy rigs and drilling platforms, mid-market business aircraft, coastal vessels, smart passenger ships and urban air mobility.

Bringing together the lowest average latency and fastest average speeds with unique resilience, ORCHESTRA aims to eliminate the industry-wide challenge of congested network ‘hot spots’.

The company says its existing GEO satellites – both GX and L-band – will continue to provide global coverage, high performance, security and resilience. Terrestrial 5G adds ultra-high capacity in busy ‘hot spots’, such as ports, airports, and sea canals. A small constellation of LEO satellites will layer additional high capacity over further high-demand areas such as oceanic flight corridors.

The network will use ‘dynamic mesh’ technology, which allows individual customer terminals to direct traffic to and from other customer terminals. This means that a ship within reach of a 5G ground station can receive ample capacity for its own needs as well as route capacity onwards to other vessels beyond terrestrial reach. This effectively creates a mobile web of terminals that extend the network’s reach and improve its performance and resilience.

“ORCHESTRA ensures Inmarsat is well positioned to deliver long-term, profitable growth by delivering new services to existing customers, targeting near-adjacent market segments, and maintaining a strong competitive position,” says Suri.

“We plan to focus initially on delivering the ORCHESTRA terrestrial network, while preparing for a future LEO constellation in the range of 150-175 satellites. This is a highly cost-effective approach that leverages Inmarsat’s leading GEO satellite networks as part of ORCHESTRA’s unique multi-layer architecture.”

The initial five-year (2021-2026) total investment for ORCHESTRA is expected to be in the order of $100m.
