Accuracy analysis of two delay discriminators when receiving navigation signals with BOC(1,1) modulation is executed. It is shown that the early-late discriminator gets the best accuracy characteristic. Discriminator with early-late and vary early-vary late reference signals has worse accuracy characteristics. Using this discriminator may lead to even lower accuracy characteristics than in the case of using BPSK(2) signal. Recommendations on using delay discriminators when receiving navigation signals with BOC(1,1) modulation is formulated.
