ABSTRACT

Errors in determination of refraction corrections to the data of satellite position measurement methods based on "the mapping functions" considering dependence of corrections on the zenith angle of an observed object, are studied. It is displayed that ignoring of the finitude of an object altitude at the development of these functions can result in an error in determination of the path refraction curvature from few millimeters to tens centimeters in the zenith angles range 80... 90°. The error in refraction angle determination for the same range of the zenith angles can amount to from few tens seconds to hundreds ones. A simple method of significant decrease of these errors is proposed.
