Abstract :
In this paper, a vector delay lock loop (VDLL) which is utilizing navigation results to track code signals is designed in a software GPS receiver. And the performance of it is analyzed in a point of tracking accuracy and compared with that of scalar delay lock loop (SDLL). Moreover the analyzed performance of VDLL is also confirmed by experiments. Finally, the performance of VDLL can be expected for any environments and the loss of lock can be determined by this result.
