About the Inmarsat C system

JRC JUE-85 Inmarsat C is a digital satellite communication system whereby anything that can be encoded into digital format, whether text, numeric data from instruments or other information can be sent and received over the system. A simple user interface allows sending and receiving messages.

Store and forward messages

The Inmarsat C system is known as a store-and-forward messaging system. When sending a ship-to-shore message, it is edited on the Data Terminal Equipment(DTE) and then transmitted in a series of data packets to an Inmarsat C land earth station (LES). The LES acts as an interface (or gateway) between the satellite and the telecommunications network on land. The LES stores the data packets, assembles them into a single message and forwards it (hence the term store-and-forwarding) over the telecommunication network to its addressed destination.

Distress alert

Your vessels ID, position, course ,speed, date and time is acquired either manually or from a GNSS receiver, such as GPS, allowing you to send a distress alert simply by pressing and holding the dedicated built-in distress button.
