GPS has been more and more important in people's life, which can provide accurate positioning for us.However, under realistic conditions GPS signal is very weak, it is easy to be outside intentional and unintentional interference, and thus can't achieve good positioning.This article describes the basic composition, structure and typical applications such as GPS satellite navigation system, followed by introduction of the principle of anti -jamming, anti -jamming analysis of satellite navigation needs, combined with the principle of anti -jamming system design platform to platform for the overall design, combined with the overall framework of the platform, designed the anti -jamming of RF circuits and digital hardware overall system.In this paper, mainly from the spatial and space-time domain algorithm anti -jamming anti -jamming algorithm.Because airspace anti -jamming algorithm is simple to implement, it can well suppress narrowband interference; at the same time, space-time domain algorithm on the basis of anti -jamming for wideband interference suppression also have a good effect.
