Propagation Delay in the Atmosphere


  • D. M. LeVine


Calculations of the propagation delay due to the atmosphere in satellite-to-earth communication are reported for the frequency range 1 to 15 GHz. A spherically symmetric, smoothly varying model is assumed for the atmosphere, and the techniques of geometrical optics are employed. The difference between the actual propagation delay and the delay which would occur in free space is presented for the lower atmosphere, the ionosphere, and the composite atmosphere.
