Correction for Atmospheric Refraction in an Airborne, Operational Environment

Abstract

A scheme for correcting for the effect of atmospheric refraction is described. The scheme minimizes the amount of computation required in real-time applications. Values derived reproduce observed data very well. There is a residual uncertainty in typical airborne applications; using the simplest scheme this amounts to about 33 micro r. A few suggested improvements to the scheme reduce the uncertainty below 10 micro r.
