Dilution of Precision and Total Interference Level on a GPS+Galileo Compatible Receiver A Global Perspective

D. Fernandez Prim

Abstract:	In a GPS+Galileo scenario and from a worldwide point of view, this contribution evaluates the use of higher elevation masking angles at the user receiver antenna while keeping positioning performances comparable to those achieved in a GPS-only scenario. By comparing suitable statistical figures of merit that account for time and geographical fitting of scenarios in terms of PDOP and receiver-estimated code delay jitter, it is hereby shown that performance equivalence is observed for a receiver antenna masking angle of 10° in a GPS-only scenario, and for 16.5° in a GPS+Galileo constellation. This fact is proposed to be applied as a simple measure to increase the robustness of mass-market receivers to external interference sources and multipath.
