From perspective GLONASS navigation satellites there will be transmitted signals with frequency and code division. Receiving one type of these signals is accompanied by intersystem interferences generate by other type of these signals. In the article there is given analyses of navigation signal delay accuracy in a navigation receiver when there is only signals with frequency division or the aggregate of signals with frequency and code division. There is shown that when processing open access signals with frequency division and receiving the aggregate of signals with frequency and code division delay tracking error increases in 6−10 times and may be up to 2−4 meters. Using optimal filtering theory methods there is synthesized compensating delay tracking algorithm when processing an open access signal with frequency division. Using this algorithm one can decrease an delay tracking error by 2-4 times as compared with a standard delay tracking algorithm. In this case delay tracking error doesn't exceed 0,8 meters.
