Short propagation time in ground-based navigation systems allow to neglect Earth turning at propagation time. In global navigation satellite systems (GLONASS, GPS and so on) that time rises steeply. As a consequence that neglecting may bring to shifts in navigation receiver coordinates up to several tens meters and to shifts of its velocity vector components up to several cm/c. Allowable errors in up-to-date global navigation satellite systems greatly less then mentioned coordinate shifts and comparable with velocity vector component shifts. It is cause the necessity to develop Earth rotation effect methods under pseudorange and pseudodoppler measurements processing in global navigation satellite systems. In the paper for pseudorange processing it is consider two possible algorithms of Earth rotation effect. Both algorithms use iterative nature of nonlinear equation system solution search, which lies in the basis of pseudorage processing. These algorithms differ each other only computing peculiarities. In the case of pseudodoppler processing it is found in the paper simple formula for Earth rotation effect correction.
