Description
Summary:This paper presents experimental results showing the impact of the proposed LightSquared Long Term Evolution (LTE) signals on reception of both Global Positioning System (GPS) and Galileo civil signals in the L1/E1 band. A model for determining the impact of the interfering signal on the victim Global Navigation Satellite System (GNSS) receivers is also provided and this model is validated against the experimental data. It is shown that Galileo E1 Open Service (OS) receivers will be, in general, marginally more susceptible to this form of interference due to its greater proximity to the edge of the L1 band (as will be the new GPS III civil signal receivers in this band). While it appears that, for now, the LightSquared network will not be deployed, the approach taken and the results obtained herein can be readily adapted for any future signal that may take the place of LightSquared.
