This paper describes the search algorithms of the GLONASS signals of code division. GLONASS signals structure open and unauthorized access described briefly. Methods for separating the time-division multiplexing pilot and information components GLONASS signals of code division discussed in this paper. Various approaches of the search procedure for GLONASS signals of code division are shown. Overview of BOC-signal search algorithms is presented. Description of BPSK-like and SCPC algorithms and mathematical description of this class algorithms are shown here. Also this paper briefly describes the principle of BUMP-JUMP algorithms. Testing the BPSK-like and SCPC algorithms for searching GLONASS signals of code division L1OC described in the article. Comparison of coherent integration algorithm for searching GLONASS signals of code division provided for BPSK-like and SCPC algorithms with different search delay step. The best algorithm of the considered algorithms for GLONASS signals search of code division is shown in this paper.
