Abstract:	The results of the interference measurement campaign carried out on board of a large container ship over the timespan of 2.5 months are presented. The interference situation in L1/E1 and L5/E5a frequency bands of GPS/Galileo that is representative for many maritime signal environments is characterized by observing the variation of the received IF power. Four detected interference events in L1/E1 band are presented. The interference effect of the signals of Distance Measurement Equipment (DME) in L5/E5a band is assessed. The characteristics of observed man-made radio emissions in both frequency bands are analyzed by using the high-rate recorded data. The design of the measurement system and its components is discussed in details.
