Which statement accurately describes the strengths of GPS?

• A. Highly accurate only.
• B. Continuously updated but 2D navigation.
• C. Provides only latitude data.
• D. Highly accurate, continuously updated, and provides three-dimensional navigation information.

Answer: (D)

GPS excels because it delivers a precise position in three dimensions with updates in real time. A receiver uses signals from multiple satellites to solve for latitude, longitude, and altitude, giving you not just where you are on a map, but how high you are above sea level as you move. This combination—high accuracy, continuous updates, and true 3D positioning—makes GPS reliable for real-time navigation in three dimensions. Statements that say it’s only 2D or only latitude miss essential parts of what GPS provides, while saying it’s only highly accurate ignores the ongoing, dynamic nature of the data.
