The propagation velocity is not constant in ground waves.(a) True(b) F

1.	The propagation velocity is not constant in ground waves.(a) True(b) FalseThe question was asked during an interview.This question is from Radio Propagation and Noise Characteristics in section Terrestrial Radio Navigation System of Avionics
Answer» Right choice is (a) True The best EXPLANATION: A characteristic of GROUND WAVES is that their PROPAGATION velocity is not entirely constant. While the variation is quite small, it is sufficient to limit the ability to obtain fixes at EXTREME ranges as good as the instrumentation might otherwise permit.
