The mathematical model of the frequency discriminator of the multichannel multisystem receiver of navigating equipment of the consumer providing joint processing of different types of navigating signals in the conditions of various type of hindrances is investigated. Curves of discrimination characteristics are received both at separate processing, and at joint simultaneous processing of navigating signals and dependence of probabilities of failure of tracking a navigating signal on the relation a signal-noise on receiver NAP input at influence of a hindrance with various width of a spectrum. It is shown that a steepness of the discrimination characteristic of in common processed navigating signals above, than at separate processing. Primary joint processing of different types of navigating signals allows to improve noise immunity НАП at influence of hindrances with width of a spectrum ≥ 10 MHz.
