Popis:	Signal acquisition plays important role in the estimation of navigation solutions as precise values of code phase and carrier frequency yield more accurate results in positioning systems. Software-defined radios are computationally expensive so we need the solution to reduce the time complexity and processing power. In this paper, we have described and demonstrated the parallel code phase search acquisition method for software-defined GPS by using python. We have compared the computational requirements of the implemented method and other signal acquisition methods. The experimental result shows the difference between the acquisition output of the visible PRNs and invisible PRNs.
