Elimination of abnormally high errors of determining the coordinates of global navigation satellite system receivers

The approaches that allow to eliminating abnormally high measurement errors in the coordinates of global navigation satellite system receivers by the use of the behavior of the signals for both individual satellites and data signals obtained in solving the navigation problem is discussed. The effectiveness of the proposed methods is evaluated using experimental data, the fluctuations in the coordinate measuring points Kharkov, Poltava, Sumy, and Smela.
