Abstract	This Note presents a description of the algorithms used to determine the position of pixel hits and its error. Two estimators of the position and error of the pixel clusters have been developed. Each two estimator can be used at a different step of the track reconstruction. One can be applied initially, at the track seeding stage. The other can be used when the approximate trajectory is known. The studies of the spatial resolution of pixel hits as a function of the track impact angles are also described.
