Abstract
The detection of satellite navigation spoofing signal provides a precondition for spoofing interference suppression of satellite navigation receivers,which prevents the receivers displaying error positioning, speed measurement and timing information.After introducing the development of satellite navigation spoofing technology in the background of navigation war, this paper analyzes the difficulty,effect and adaptability of the main satellite navigation spoofing detection technologies, points out the most valuable spoofing signal detection technologies in satellite navigation receiver. At last,the trend and development direction of the spoofing detection research are summarized and prospected.
