Abstract :
The impact of multipath signals on the code phase tracking in digital GPS/GLONASS navigation receivers is analysed. As an interesting result it is for example, shown that for moderate correlator spacings a DOT discriminator DLL offers a larger potential of multipath error reduction by code phase smoothing than an EML discriminator DLL due to significantly smaller mean code phase tracking errors
