The digital model of the channel of tracking a delay of a signal of the multichannel multisystem navigating receiver is offered at joint processing of several types of navigating signals for various parametres of a hindrance. Discrimination characteristics are received and analysed both at separate processing, and at joint simultaneous processing of different types of navigating signals for various algorithms of work of time discriminators. Research and an estimation of probability of failure of tracking a navigating signal is conducted at various levels a signal-noise on an input of the navigating receiver for expedient алгаритма works of the time discriminator. It is shown that primary joint processing of different types of navigating signals allows to raise noise immunity of the receiver of na-vigating equipment of consumers on 3÷6 dB.
