Abstract:	Robust Interference Mitigation (RIM) denotes a class of algorithms able to reduce the impact of jamming and interference on Global Navigation Satellite System (GNSS) receivers. These algorithms are based on principles of Robust Statistics and operate at the signal processing level. While significant analysis has been performed to demonstrate the effectiveness of RIM in mitigating interference at the signal level, little work has been performed to assess the impact of these techniques in the measurement and position domains. This paper provides an assessment of RIM techniques at the measurement and position level. In particular, several data collections were performed in the presence of interference and the impact of RIM was evaluated in the position and measurement domains. Four mitigation techniques are analysed and it is shown that RIM does not introduce biases enabling consistent position solutions even in the presence of significant levels of interference.
