Inmarsat Orchestra 'dynamic mesh' network to use 5G, low orbit, and geostationary satellites

Customers will be able to use their terminals to expand coverage to other terminals within range on a network to cost around $100 million.

Satellite connectivity company Inmarsat has taken the wraps off a network it claims will be able to combine 5G, low orbit, and geostationary satellites.

Dubbed Orchestra, the company said it would need to invest in the order of $100 million over five years to get the network off the ground, as well as launch a constellation of 150-175 low-Earth orbit satellites. Work will begin on the terrestrial network.

"Inmarsat's 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," the company said.

"A small constellation of LEO satellites will layer additional high capacity over further high-demand areas such as oceanic flight corridors."

Customers will be able to mesh the connectivity between their terminals, with the example put forward being a ship connected to a 5G tower forwarding capacity to other vessels "beyond terrestrial reach".

"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," Inmarsat CEO Rajeev Suri said.

The company said new services used by the network could 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.
