Research on GNSS System Single Interference Direction Finding

Interference Direction Finding for Aviation Applications of GPS

The Local Area Augmentation System (LAAS) is being developed by the US Federal Aviation Administration (FAA) to provide satellite navigation performance compliant with the stringent requirements for aircraft precision approach and landing. A primary design goal for LAAS is to insure that failures occurring in the ground or space segments be eliminated by the ground system before differential co...

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...

UNSW 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 ...
