Inmarsat plc is a leading provider of global mobile satellite communications, offering voice and high-speed broadband services across maritime, aviation, government and enterprise sectors.

Inmarsat traces its origins to 1979, when it was established as the International Maritime Satellite Organization (INMARSAT) under the auspices of the International Maritime Organization. The company was privatized in 1999 and subsequently listed on the London Stock Exchange, expanding its services beyond maritime safety to encompass aviation, land mobile and broadband solutions. Over the decades, Inmarsat has continually upgraded its satellite fleet and ground infrastructure to meet rising demand for reliable, global communications.
Under the leadership of Chief Executive Officer Rajeev Suri, Inmarsat has pursued strategic initiatives to enhance its network capabilities and broaden its addressable markets. The company’s satellites and ground stations operate in key regions including the Atlantic, Pacific and Indian Ocean basins, North America, Europe and Asia Pacific. By combining global coverage with tailored service offerings, Inmarsat positions itself as a critical communications partner for customers requiring uninterrupted connectivity in remote and high-mobility environments.
