|Abstract:||Interference is a growing concern among GNSS users, particularly in parts of the world where radio frequency (RF) transmission is not strictly regulated. Intentional interference and jamming is cheap and relatively easy to obtain in the form of Personal Privacy Devices (PPD). These devices can sometime cause unintended interference and jamming to important infrastructure like an airport (Mitch, et al. 2013). This paper describes two methods for creating interference maps using NovAtel OEM7’s Interference Tool Kit (ITK). ITK can be used to measure the received interference power, which is more accurate and precise than other measurement types typically used for power difference of arrival: AGC (e.g. Blay and Akos, 2018, Borowski et al 2012, Thompson et al. 2011) and CNo (e.g. Strizic et al., 2018). Similar to the more common methods, when data is collected for an area around a static and continuously operating interference source, it can be used to map out the interference over the affected area. This paper extends the method of Alves, et al. (2018) with two additional and improved methods for mapping the interference and creating a likelihood map showing the position of the interferer. This paper includes three case studies with live (real-data) interference sources from India, Canada, and Japan.|
