Question 848Navigation General

The correct answer is D) good fix. A low HDOP number, such as 2, indicates a good fix. HDOP is a measure of the quality of a GPS signal, with lower numbers representing better signal quality and a more accurate position fix. A low HDOP value means the satellites used in the position calculation are well-spaced, resulting in a more precise horizontal position. This is important for navigation and position-fixing, as a good fix with low HDOP is necessary for safe maritime operations. The other options are incorrect because a low HDOP does not indicate a poor fix (A) or poor signal quality (B), but rather the opposite - a good, high-quality fix. A high HDOP value would indicate a poor fix or signal quality.
