New promising signals with BOC modulation are introduced as part of the GLONASS navigation system modernization. These signals would provide high positioning accuracy and reduce the impact of multipath signal propagation, especially important in urban areas. Usage of BOC-modulated signals results to the complication of signal processing methods or deterioration of certain characteristics of consumer equipment. This article describes methods and probability characteristics of acquisition methods of BOC-signals. Several methods of BOC-signal ac-quisition are described. The influence of the uncertainty areas sizes on the search performance is examined. An experimental study of the suggested methods is held on full-featured navigation equipment. The results of investigations, recommendations on the appropriate-ness of the BOC search methods are described in the end of this article.
