Assessment Method of Multipath Mitigation Performance for GNSS Antenna with Receiver Algorithms

Figure 4

In this figure, the chip width is set to as the chip width of C/A code in GPS, the early-late spacing of correlators is and the radius of semiopen land is 1000 m. (a) shows propagation time delays of multipath signals at horizontal surfaces with different antenna installation heights (). (b) shows delays at inclined surfaces with different satellite elevation angles (). Four horizontal dotted lines marked from top to bottom represent delay thresholds , , , and . Only multipath signals with delays between the top two lines and the bottom two lines have impact on PPE.
