Since the received GNSS signals are inherently very weak, a simple GNSS signal jammer can easily degrade the measurement quality, or completely deny GNSS signal reception at the receiver. In the context of collaborative navigation, the user-to-user radio links help the cooperating receivers/nodes to navigate in the compromised environment. Possibility to share information between the nodes allows not only for improving positioning and situational awareness of the cooperating group of users, but also for pro-active localization of the identified jamming source. The focus of this paper is on localization of Radio Frequency Interference (RFI) by a group of collaborating users. A synthetic array principle based on the Carrier-to-Noise Density Ratio (C/N0) measurements is used and applied to a multi-user scenario. To evaluate the performance of multi-user RFI localization, a series of experiments in a controlled lab environment have been carried out. This paper discusses the results as well as the limitations of the implemented technique.
