Increasing noise immunity at selection information navigation with satellites GLONASS / GPS

Receiving data from board of satellite is an integral part of any navigation receiver. The data transfer speed for the GLONASS / GPS is 50 bit / s. Error-free receiving of information is a big problem the extremely because of a low level of the received signal. The receiving procedure of information functionally divided into two parts: hardware and software. That is made in the navigation receivers, manufactured by the company «Orizon-Navigation». In the hardware (the navigation correlator) are formed millisecond portions of demodulated signal. The software is restores the original information from the obtained readings . Way to implement this algorithm in the receivers company «Orizon-Navigation» is presented in this paper.
