Abstract
A method of mitigating multipath interference in a global navigation satellite system (GNSS) includes receiving GNSS signals from a plurality of space vehicles emitting at least L5 and L1/L2 band signals, determining, for each L5 and L1 and/or L2 signal, a pseudo-range based on the signal, and determining a residual for each L5 and L1 and/or L2 signal from each space vehicle, wherein the residual is the difference between the range of the space vehicle to the position predicted based on data from a previous time period and the pseudo-range. The method further includes determining a statistic based a comparison between residuals of the L1 and/or L2 signals and the residuals of the L5 signals. If the statistic is above a predetermined threshold, the overall position is determined based on a subset of the signals, the subset comprising the L5 signals and wherein at least one of the L1 and/or L2 signals are excluded from the subset. If the statistic is not above a predetermined threshold, the position is determined based on the L1 and/or L2 signals and the L5 signals.
