Integrated processing of satellite navigation signals

This paper studies a satellite navigation signal processing method with the integration of software and hardware. The steps are as follows: there are two sources of received data, which can be either the intermediate frequency data collected by the receiving antenna and the RF front-end, or the data input module; The collected intermediate frequency data is input into the hardware correlator or software correlator for correlation processing; A single channel correlator is designed for each satellite signal. The hardware correlator is driven by the clock signal, and the software correlator is driven by the logical clock signal. The mathematical models and functions of the two are the same; The results of the correlator are input to the subsequent baseband processing and navigation solution module. The baseband processing and navigation solution program is designed by Hal(Hardware Abstraction Layer), so that the receiving algorithm based on the software receiver design can be directly transplanted to the hardware receiver module. This paper provides a basis for the direct application of the receiving algorithm results developed based on the software receiver to the hardware receiver.
