The International Mobile Satellite Organisation (IMSO) is the inter-governmental organization which was formed to oversight of certain public satellite safety and security communication services provided by mobile satellite communication systems.
The Convention on the International Maritime Satellite Organization was adopted by IMO in 1976 to establish and oversee satellite communications for shipping.
Under the treaty, the International Mobile Satellite Organization (IMSO) has been established as the inter-governmental body that oversees the provision of certain satellite-based maritime distress communication services, specifically those used in the Global Maritime Distress and Safety System (GMDSS).
IMO appointed it as LRIT Coordinator (International system for the Long Range Identification and Tracking of Ships) to ensure the operation of the international system for the Long Range Identification and Tracking of Ships (LRIT) worldwide by auditing and reviewing the performance of the system.
IMSO: Historical Retrospect
The establishment of the Organization was based on two international public law instruments developed under the guidance of the International Maritime Organization (IMO). These are:
Both instruments entered into force on 16 July 1979.
The purpose of Inmarsat was to make provision for the space segment necessary for improved maritime communications and, in particular, for improved safety of life at sea communications and the Global Maritime Distress and Safety System (GMDSS). This purpose was later extended through amendments to the Convention and Operating Agreement to provide the space segment for land mobile and aeronautical communications, and the name of the organization was changed to the International Mobile Satellite Organization to reflect the amended purpose.
Inmarsat was structured with three principal organs:
