On the Impact of Channel Cross-Correlations in High-Sensitivity Receivers for Galileo E1 OS and GPS L1C Signals

Figure 7

Discrimination function (coherent Early-Late, Δ = 1 chip) obtained for a GPS L1C signal using Weil codes (10 ms, PRN 1). Received signal: both data and pilot channels, local signal: pilot channel only. The S-curve does not result symmetrical around the zero lag (bias = 0.09 m).
