There is a slight slowing in the atmosphere and that reduces the 
absolute wavelength by a very small amount.
For civilian use, that kind of error is irrelevant because it only 
results in a small height error.
Note, the ECI coordinates are the same along any particular radius 
vector from the Earth's centre so height doesn't matter much because 
true surface height is already known at every point on the planet. The 
same applies to receiving clock error.
If the number of wavelengths in each of the four signal paths is out by 
about the same proportion, that only results in a height error.
