Abstract: In this paper, the authors aim at the problem that GPS receivers often lose useful signals because of the effect of various interfering signals in the period of receiving signals. As a sequel of it, GPS receiver will be out of work and can not provide users with its excellent support for accurate navigation and positioning. So the authors put forward a method to resolve this problem by adding an adaptive anti-jamming module to the antenna of GPS receiver, and select TMS320C6416 chip to realize this design.
