a NO. 59, and b NO.1. The figure demonstrates the extraction of multipath error for select satellites, where (a) and (b) illustrate satellite 59 and 1, respectively. There was an obvious effect in eliminating the original constant error of GEO satellites with antenna jitter. The code multipath error of the static antenna is slowly changed in the figure. In contrast, the multipath error of the jitter antenna is smaller than that of a static antenna. Specifically, MS error for the B1 carrier frequency for the No.1 satellite, decreased from 0.33 m to 0.15 m post antenna jitter. Furthermore, the range error is reduced from 2.08 m to 0.76 m. This indicates that the multipath error can be suppressed by the jittering antenna.
