Which of the following statements about NAVTEX is true?

NAVTEX, which stands for Navigational Telex, is an important system used for broadcasting maritime safety information (MSI) to ships at sea. It operates by transmitting navigational and meteorological information, including weather updates, search and rescue notices, and other safety-related information crucial for maritime navigation.

The correct statement regarding NAVTEX is that it receives MSI broadcasts using SITOR-B (Simplex Telex) or FEC (Forward Error Correction) mode. These modes allow the transmission of information with specific error correction capabilities, ensuring that the data received by ships is accurate. This is particularly important in maritime environments where clear and reliable communication can be critical for safety.

While there are other features and capabilities of NAVTEX, such as its ability to cover specific geographical areas and use specific frequencies rather than a single worldwide frequency, the use of SITOR-B and FEC mode for data transmission is a fundamental characteristic that explains why the selected answer is correct. This detail highlights the technology involved in transmitting safety information efficiently and reliably to maritime operators.
