🔍 Key Concepts

• FEC (Forward Error Correction) vs. ARQ modes in NBDP (Narrow Band Direct Printing) • Typical uses of SITOR/NBDP in the GMDSS system • Difference between MSI (Maritime Safety Information) broadcasts and commercial/company traffic

💭 Think About

• Ask yourself: When a transmission is FEC, is it meant for one specific ship, or for all ships in range to receive simultaneously? • Which types of messages must be received without needing a return link from the ship (broadcast only)? • Look at which options mix safety/broadcast services with private/company communications—does FEC normally carry private traffic or general broadcasts?

✅ Before You Answer

• Verify what MSI (Maritime Safety Information) includes: NAVTEX, SafetyNET, NAVAREA warnings, weather, etc. • Check whether company messages over NBDP usually use ARQ (two‑way, acknowledged) or FEC (one‑way broadcast). • Confirm which services listed (NAVTEX, HF MSI, VHF MSI, traffic lists, weather) are typically delivered as broadcasts to all ships rather than addressed to a single ship.
