It is necessary to determine bounds of information symbols (get clock synchronization) during acquisition stage. Usually method of tact and string synchronization is to find second mark. Maximum time to wait second mark is 6s for GPS and 2s for GLONASS. Optimal clock synchronization algorithm based allowing to avoid limiting if accumulation time during synchronization stage of GNSS receiving synthesized. Characteristics of found algorithm are investigated. Simplified algorithm was found. It is close to original and much more simple for implementation at the same time. Characteristics of found algorithms was got using method of statistic modeling. Analysis of the characteristics shows the feasibility of the proposed algorithms in GNSS receivers to increase performance on the acquisition stage.
