description: The work is devoted to the development and implementation of an algorithm for evaluating and compensating of inaccuracies in the local oscillator tuning to improve positioning accuracy. In the course of the work, simulation modeling was carried out and the software implementation of the proposed algorithm was performed using the MATLAB soft-ware. Itâs performance was verified on recordings of GPS signal. Algorithms for tracking, subframe synchronization and collection of navigation information were implemented in the TMS320C6455 signal processor, which is built into the GPS sig-nal receiving device, which was provided by the âSpecial Technological Center LLCâ. As a result, the local oscillator inaccuracy compensation algorithm was devel-oped. It is shown that the proposed algorithm allows to achieve positioning accuracy, which can be obtained in the case of using an ideal local oscillator without frequency deviations. The algorithm can be used to process signals of different GNSS.
