Abstract
The article presents the analysis results of global navigation satellite systems BOC(n, m) signals detection. The analytical ratios presenting statistical characteristics of navigation signals detection are given. Characteristics of L1OCp GLONASS open pilot signals detection using the BPSK-like detector and the detector with subcarrier frequency removal at various coherent accumulation intervals are received. The capability of flexible time control of the coherent accumulation is shown if reception satellite L1OCp GLONASS open pilot signals is needed various power. Losses at L1OCp GLONASS open pilot signal detection depending on delay and frequency indeterminacy in a search cell are analyzed. The conclusion is made about the necessity of choosing search cell size taking into account the losses considered and detection characteristics required.
