How does troposphere affect the satellite signals?(a) Reduces velocity

1.	How does troposphere affect the satellite signals?(a) Reduces velocity(b) Reflects the signals(c) Refracts the signal(d) Bit inversion occursThe question was posed to me in an international level competition.The doubt is from Atmospheric Effects on Satellite Signals topic in section Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» The correct OPTION is (a) Reduces velocity Explanation: The major sources of errors are when the SIGNAL pass through the atmosphere. The TROPOSPHERE causes the propagation velocity of the signal to be slowed, compressing the signal wavelength.
