Which data types does GPS provide?

• A. Speed over ground, headings, rate of climb
• B. Altitude, attitude
• C. Thrust, drag
• D. Temperature, humidity

Answer: (A)

GPS primarily provides position and motion information. It yields speed over ground and track (heading) as you move across the Earth's surface, and if altitude data is available with precise timing, it can also give vertical speed (rate of climb). Attitude (pitch, roll, yaw) is not provided by GPS alone, as that requires orientation sensors like an IMU. Thrust and drag are propulsion and aerodynamic forces, not GPS measurements, and temperature and humidity are environmental data, not GPS outputs. So the option that includes speed over ground, headings, and rate of climb matches what GPS can supply.
