Technology of Interference Monitoring for GNSS

GNSS are facing with increasingly complex electromagnetic environment, and various kinds of interference have caused a serious impact on the normal operation of the satellite navigation systems. Therefore, the effective monitoring of interference of the satellite navigation system is of great significance on ensuring the normal operation of satellite navigation systems and providing guidance on anti-jamming e- quipment development. In this paper, first we analyze the development of satellite navigation systems a- round the world and summarize the four categories of key technology for satellite navigation interference mo- nitoring： Interference detection technology, interference-finding technology, interference identification technique, and interference location. For each type of the technology, we give a brief introduction of its current situation and development direction. Finally, we discuss the development direction and prospects for satellite navigation interference monitoring system in details.
