Inmarsat is a British satellite communications operator founded in 1979, originally as the International Maritime Satellite Organization, providing voice, data, broadband, and IoT services over a global L-band, Ka-band, and multi-band fleet of geostationary satellites. In May 2023 Viasat completed its acquisition of Inmarsat, and the combined company now operates Inmarsat's GX (Global Xpress), BGAN, IsatData Pro (IDP), and Fleet Xpress services alongside Viasat's ViaSat-3 constellation as a unified multi-orbit network. Inmarsat serves four core markets — Maritime (NexusWave, Fleet Xpress, Fleet One, FleetBroadband, Inmarsat C/GMDSS), Aviation (SwiftBroadband, GX Aviation, Jet ConneX, SB-S safety services), Government (L-TAC, GX, BGAN M2M), and Enterprise/IoT (BGAN M2M, IsatData Pro, IsatM2M, NB-NTN). Inmarsat operates a developer program at developer.inmarsat.com with documented APIs for BGAN network management, GSPS voice, Global Xpress, IsatData Pro messaging, Fleet Edge assurance, and Fleet Edge hardware replacement; access to interactive Swagger documentation is gated behind developer registration and approval, though the IsatData Pro Messaging API has an open-source Apache-2.0 Node.js client published on GitHub. Inmarsat is also one of the participating operators in the GSMA NB-NTN (Non-Terrestrial Network) standards work for satellite-extended cellular IoT, with Viasat-led proof-of-concept code for NIDD (Non-IP Data Delivery) published under the inmarsat-enterprise GitHub organization.
