A survey of GNSS interference monitoring technologies
نویسندگان
چکیده
With the increasing economic and strategic significance of global navigation satellite systems (GNSS), interference events also occur frequently. Interference monitoring technologies aim to monitor that may affect regular operation GNSS. can be divided into three parts: detection recognition, source direction finding, location tracking. aims determine whether exists. This paper introduces classification corresponding methods. The purpose recognition is recognize classify interference. It often combined with pattern machine learning algorithms. finding estimate signal. There are kinds methods: amplitude, phase, spatial spectrum estimation. position usually based on received signal strength (RSS), time difference arrival (TDOA), frequency (FDOA), angle (AOA) or (DOA). tracking track moving sources, it generally Kalman filter theory. summarizes their latest progress. Finally, prospects for offered.

Interference Localisation within the GNSS Environmental Monitoring System (GEMS)
Due to their low-power levels, GPS signals are very susceptible to interference from either intentional or unintentional sources. This vulnerability is further aggravated by the increased reliance of the civilian infrastructure on GPS for time synchronization. This brings about the pressing need for detection and localisation of the interferers in real-time to prevent disturbance to everyday op...

متن کاملUNSW GNSS Interference Detection Device
The radio frequency signals transmitted by Global Navigation Satellite Systems (GNSS) have very low power and are susceptible to radio frequency interference. Most GNSS receivers do not measure and quantify any interference they may be suffering; they just do what they can with the signals they receive. Interference can lead to poor receiver positioning performance and, if severe, such as in a ...
