What action should always be taken before powering down an Inmarsat-C terminal or leaving one satellite footprint for another?

🔍 Key Concepts

• Inmarsat-C terminal log-in/log-out procedures when changing satellites • How Maritime Safety Information (MSI) messages are routed to specific terminals • The role of the Network Coordination Station (NCS) in tracking which satellite your terminal is using

💭 Think About

• Ask yourself: how does the system know which satellite ‘footprint’ your terminal is in, and what step keeps the message routing database accurate? • Think about whether Inmarsat-C is designed to run continuously, or whether there is a standard procedure when shutting down or moving between ocean regions. • Consider which option describes a normal, routine procedure versus something that sounds extreme or unnecessary.

✅ Before You Answer

• Verify which action, if skipped, could cause MSI or other messages to be misrouted when you change regions or power down. • Check which choice matches standard log-in/log-out terminology used with Inmarsat-C and NCS operations. • Eliminate any answer that claims something absolute or unrealistic, such as "must never" or "no action is required", if it conflicts with how managed satellite networks usually operate.

What action should always be taken before powering down an Inmarsat-C terminal or leaving one satellite footprint for another?

An Inmarsat-C system must never be powered down or mandatory MSI messages will be lost.

Send a message to the NCS advising arrival in port or request the NCS log your terminal in with the new satellite.

No action is required -- the terminal will automatically log in with the new satellite when the NCS common channel is detected or after power up.

Log out with the current NCS to inform them you are off the air or to enable a proper log in procedure with the new satellite.
