Inmarsat-c

Introduced in 1991, Inmarsat C provides global communications in a compact package suitable for either small or large vessels. Inmarsat C offers a low-cost, two-way communications system suitable for text, data, and email. Voice is not supported.

Using a store-and-forward system, messages are prepared in advance and then transmitted via a land earth station operator (LESO) to the recipient. Useful for both ship-to-shore and shore-to-ship communications, Inmarsat C is still used extensively as a cost-effective maritime communications solution.
