In this paper algorithm for accumulating code division multiplexed GLONASS satellite navigation signals during the search procedure is proposed. Such accumulation algorithms are based on an incoherent accumulation of preaccumulated samples calculated on the integration interval for L1OCD and L1OCP signals. At the same time, the choice of the accumulation algorithm for L1OCD signals does not affect the algorithm for accumulating a L1OCP signals. A comparison is made between such algorithms and algorithms by accumulating one component of GLONASS signals during the search procedure. The simulation results many integration algorithm during search showed advantage joint search with considering all components signals compared search with considering one components and wins 2,2 dB of the interval integration 16 mc. Also the joint search advantage dependent on integration algorithms are used for each signal component.
