What is a common cause for alarm regarding the ship's position in ECDIS?

• A. Unfavorable weather conditions
• B. GPS signal interference
• C. Exceeding the speed limit
• D. Manual input errors

Answer: (B)

The selection of GPS signal interference as a common cause for alarm regarding the ship's position in ECDIS is grounded in the critical role that GPS plays in providing accurate positioning data. ECDIS relies heavily on data from GPS to display a vessel's position on electronic charts. When there is interference with the GPS signal, it can lead to inaccurate position readings, which may create a false sense of security or, conversely, cause navigational errors that could lead to grounding or collisions. GPS signal interference can occur due to various factors such as physical obstructions, atmospheric conditions, or intentional jamming. These disruptions can make navigating safely more challenging, and alarms in an ECDIS system are designed to alert the navigator to such discrepancies. Therefore, recognizing GPS signal interference as a reason for alarm highlights the reliance on satellite positioning for modern maritime navigation and the importance of ensuring that signal integrity is maintained. The other options, while they can affect navigation and safety, do not specifically trigger alarms related to the ship's position in the ECDIS system as directly as GPS interference does. Unfavorable weather conditions might necessitate alterations to navigation practices but do not inherently affect position accuracy provided by the ECDIS. Exceeding the speed limit is a regulatory
