Implementation of GPS Receiver Based on FPGA
Hongping Zhang · 2011
A GPS receiver based on FPGA was designed using SOPC technology.An acquisition strategy based on Doppler Shifting was proposed and acquisition time was analyzed.Using delay lock and Costas tracking approaches,a GPS receiver was implemented in SOPC.Experimental results showed that signal acquisition and tracking modules of the receiver functioned properly;and in static conditions,horizontal positioning precision was better than 4.5 m(Std Dev).The design on the whole is satisfactory in real time operation and it has been proved to be both flexible and extensible.
