| Summary: | The article presents a mathematical model describing the physical phenomena occurring in the GNSS radio receiver. The main subunit which focused attention was the system of GNSS receiver correlator. The process of tracking and acquiring navigation signals processed in a navigational radio receiver was analyzed in a special way. Bearing in mind that all kinds of noise and interference get through to the signals processed in the receiver, the article attempts to develop a mathematical model of the signal reaching the receiver with noise and an inappropriate signal. On the basis of the mathematical model developed, the courses of acquisition and tracking processes of SIS signals in the presence of noise and interference signal in the form of a narrow and broadband signal are presented. The final part the paper presents the results of computer simulations. Although the results presented in the paper refer to a specific GNSS receiver, they may differ depending on the types of radio navigation devices. |
