How does the ionosphere affect GPS?
A)GPS satellites orbit the Earth in the ionosphere.
B)GPS ground stations lose contact with geosynchronous satellites orbiting near the poles.
C)GPS signals must pass through the ionosphere,whose gases weaken the signal.
D)Positively charged ions in the ionosphere speed up the GPS signal,causing signal error.
E)Ionosphere gases strengthen GPS signals,improving locational accuracy.

Question

Quizplus · Accepted Answer

GPS signals must pass through the ionosphere, which can cause the signal to weaken and lead to errors in location calculations. The ionosphere contains charged particles and gases that can refract and delay GPS signals, affecting the accuracy of the location data. Several techniques, such as differential correction, are used to mitigate these effects.
