History and Background of Inmarsat

The origin of Inmarsat can be traced back to a resolution of the United Nations International Maritime Organization (IMO) in 1976. At that time, in order to improve maritime safety communications and provide distress call services, the international community decided to create a global satellite communication system. After three years of preparation, Inmarsat was officially established in 1979 and began operations as an intergovernmental organization. The original purpose was to provide reliable communication services for ships at sea, especially to ensure the safety of crew members in emergency situations.

Over time, Inmarsat's service scope has gradually expanded and is no longer limited to the maritime field. In 1999, Inmarsat transformed into a private company and changed its name to Inmarsat plc. Since then, it has continued to expand its business areas and developed diversified communication solutions for industries such as aviation, land transportation, and energy exploration. Today, Inmarsat has become one of the world's leading satellite communication service providers, with its headquarters in London, UK.
