Which term describes the phenomenon where the GPS signals take a longer path through the ionosphere, causing a delay and potential accuracy degradation?
- A.
Geodetic Anomaly
- B.
Ionospheric Scattering
- C.
Multipath Interference
- D.
Tropospheric Refraction
Correct Answer
C. Multipath InterferenceExplanation
Multipath interference occurs when the GPS signals reflect off surfaces such as buildings or bodies of water before reaching the receiver antenna. In the ionosphere, signal delays can occur due to factors like ionospheric scintillation, but multipath interference specifically refers to signals taking multiple paths, leading to inaccuracies in position calculations. Understanding and mitigating multipath effects are crucial for improving the accuracy of navigation satellite systems.Rate this question:
