← ScienceWhich outcome results when a GPS receiver in urban canyons suffers from significant multipath propagation?
A)Incorrect pseudorange distance calculations✓
B)Enhanced signal-to-noise power ratios
C)Reduced ionospheric scintillation effects
D)Accurate Doppler frequency shift measurement
💡 Explanation
Multipath propagation causes signal interference and distortion, leading to inaccurate ranging; because GPS relies on precise timing from satellites, multipath alters the perceived time of arrival causing pseudorange errors, therefore positions become inaccurate, rather than improved SNR which would require direct signals.
