| Abstract: | A design and implementation scheme of GPS receiver tracking loop based on FPGA was proposed to improve the performance of tracking loop.The basic theory of the GPS receiver tracking loop was studied and existing algorithms were analyzed.Using a FLL-assisted PLL loop,a dynamic code loop and a PLL-assisted DLL architecture and taking full advantages of the interworking between hardware and software in Xilinx's FPGA,the scheme was implemented in one FPGA chip,which can improve operation efficiency of the syste... |
