This research aims to improve the satellite navigation systems accuracy due to the correction of satellite signals multipath<br />propagation errors. The multipath effect errors reducing problem on the navigation solutions accuracy is one of the most pressing problems<br />in modern satellite navigation, because the error introduced by the satellite signals reflections can be up to tens of meters, which greatly<br />complicates the precise positioning task in difficult terrain. For example, in dense urban development conditions, with using satellite<br />navigation technologies in design and construction.<br />Objective. The main objective is to reduce multipath error signal at least one order, which will significantly increase the accuracy of the<br />navigation task solution.<br />Method. When solving the relative positioning tasks, it is often difficult, basically from a financial point of view, to provide the entire<br />receivers set with the same antennas using hardware methods. Including because of the effective use of funds, it was decided to consider the software methods. In this article, is considered a method for correcting the multipath error by using the wavelet transform of incoming navigation signals.<br />Results. The efficiency the proposed method is demonstrated on real satellite navigation data. Software implementation and all<br />experiments are made by the computer mathematics package MATLAB. The results showed the multipath correction method efficiency and<br />confirmed the expected accuracy after processing by the proposed technique.<br />Conclusions. Based on the results obtained in this paper, we can conclude that the use of wavelet transformation improves the<br />measurements quality used to obtain a navigation solution, thereby increasing its accuracy, regardless of terrain.}, number={1}, journal={Radio Electronics, Computer Science, Control}, author={Kozadaev, K.
