The paper presents a method for the initial azimuth psi 0 selection in Land Navigation Systems (LNS), applying the ZUPT (Zero–velocity UPdaTe) technique. This technique is understood as a correction of the initial setting psi 0 achieve the best accuracy of the navigation. The case of the inaccurate initial azimuth during stopping of the vehicle (after short drive) in order to setting is considered. The first part of the work describes the Static Initial Azimuth uPdate (SIAP) method. Next, the vehicle stopping criteria and their influence on the accuracy of the navigation are discussed. Then, the initial azimuth optimization method is proposed. Finally, the simulation results and conclusions concerning further research are presented.
