What does GPS provide to an aircraft?

Explanation:
GPS provides the aircraft’s position on the earth, its speed over the ground, and the direction it’s moving (course over ground). The receiver determines position from satellite signals and uses Doppler measurements to compute velocity, giving you ground speed and track. It does not directly supply airspeed, attitude, or wind information; airspeed comes from the air data system, attitude from attitude sensors, and wind is inferred rather than broadcast by GPS.
