What is the IMSO ?
The International Mobile Satellite Organization (IMSO) is the inter-governmental organization whose primary purpose is the oversight of certain public satellite safety and security communication services provided by mobile satellite communication systems.
The International Mobile Satellite Organization (IMSO) is based on the provisions of the Convention of the same name, which defines the public services that the IMSO oversees, such as the satellite services required for the GMDSS (Global Maritime Distress and Safety System).
The IMSO has recently been entrusted with the coordination of the LRIT system, which was gradually implemented from 2004 to 2009 under the IMO, in order to improve the safety, security and protection of the maritime environment against terrorist threats (transmission by each ship every six hours of its identity and dated position, collection and dissemination of messages ashore by "data centres" linked to the flag State). This system allows States Parties to receive position reports from ships under their flag, as well as from foreign ships bound for their ports or in the vicinity of their coastline.
For GMDSS and LRIT, the regulation of the systems is decided by the IMO, with the IMSO involved in monitoring or auditing functions.
