Q

If you are tracking the AOR-W satellite and wish to communicate by F77 voice using LES Southbury with another ship tracking the AOR-E satellite what is the proper procedure?

🔍 Key Concepts

• Inmarsat ocean regions (AOR-W vs AOR-E) and how ship earth stations are logged into just one region at a time • The role of a Land Earth Station (LES) and its 3‑digit LES code (e.g., Southbury) in setting up an F77 voice call • How an Inmarsat F77 ship‑to‑ship call is structured: LES selection, then full international mobile number (IMN) of the called ship

💭 Think About

• First identify which LES code in the options belongs to Southbury. Eliminate any answers that select the wrong LES number. • Think about how a ship logged into AOR‑W can call a ship logged into AOR‑E: does each ship need a different LES, or can the call be routed through a single LES? • Look at the number after the LES selection: which choice looks like a properly formatted Inmarsat F77 ship number (starting with the correct service code and region indication for the called ship)?

✅ Before You Answer

• Verify from your Inmarsat reference table which 3‑digit code is assigned to LES Southbury. • Check that the dialed number after LES selection matches the format for an Inmarsat F77 ship’s IMN (correct length and initial digits). • Confirm that the sequence of steps is correct for ship‑to‑ship via LES: select LES first, then dial the called ship’s full IMN, including any required international/service prefixes.
