Figure 5: Discrimination function (coherent Early-Late, Δ = 1 chip) and its zoom, obtained for a Galileo E1 OS signal using memory codes (4 ms primary codes, 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 = 6.61 m).
