On Atmospheric Effects on GPS Surveying
The aim of this paper is to study the atmospheric effects and the mechanics of delay of radio signals, and to search for a better approach for reducing the effects of the atmosphere on GPS surveying. The stresses of our investigations are put on cases with low elevation angles and single-frequency receivers. Several important models, widely used, are tested by direct comparison of their effects on positioning with the real GPS measurement data, instead of comparison of compensation or characteristic quantities, such as TEC, etc.
