Abstract |
Software defined GPS receiver has three main modules. They are acquisition, tracking and navigation modules. This paper describes the implementation and analysis of acquisition and tracking for GPS software receiver. For signal acquisition, the analysis of three acquisition algorithms is implemented and analysed. In tracking, there are two main tracking loop: code tracking and carrier tracking. This paper emphasizes on code tracking loop which is also called Delay Locked Loop (DLL). Code tracking loop is implemented and the effect of changing parameters such discriminator spacing and loop noise bandwidth is also described. In case of satellite signals, not only real signals from GPS front-end but also generated signals from signal simulator are used for analysis of acquisition algorithms and tracking results. GPS signal processing for acquisition and tracking is performed by using MATLAB programming language. Keywords - GPS, Software Defined Receiver, Signal Processing, Acquisition, Tracking. | |||||||||
