With respect to failure warnings and status indications, GPS receivers should provide, at a minimum, __________.

Correct Answer: Option D — a warning of loss of position

IMO and USCG navigation equipment standards require GPS receivers to provide an immediate alarm upon loss of position fix. This ensures the navigator is alerted when the system can no longer provide reliable navigation data, preventing reliance on stale or inaccurate information during critical maneuvering or coastal transit.
