What service allows terrestrial information providers to send general messages to predefined groups of subscribers?

The correct choice identifies FleetNETTM as the service that facilitates terrestrial information providers in sending general messages to predetermined groups of subscribers. FleetNETTM operates as a two-way communication system that enables the dissemination of information specifically tailored for maritime users. This communication service is commonly utilized by fleets of vessels that need to receive continuous updates such as operational notices, weather messages, and other relevant maritime information.

The system employs a method that allows selected receivers, or subscribers, to access messages while filtering out unnecessary communications that are not relevant to them. This capability is particularly beneficial in maintaining operational efficiency and ensuring that information reaches those who require it without overwhelming users with irrelevant data.

In contrast, SafetyNETTM serves a different purpose primarily focused on broadcasting safety-related messages and navigational warnings, making it less appropriate for generalized information dissemination. COSPAS-SARSAT is dedicated to search and rescue operations, and InfoNET, while potentially related, does not serve the same specific function as FleetNETTM in the context of maritime communication.
