GPS carrier phase measurements are corrupted
by multipath signals that can significantly affect the quality
of data used for static and kinematic positioning applications.
In order to characterize carrier phase multipath, various
relationships between parameters such as the multipath amplitude,
phase and frequency with the satellite dynamics, antenna-
reflector distance, antenna-reflector geometry, signal frequency
are shown. Multipath spatial and temporal correlation are
analyzed using simulated and field data. The mitigation of
GPS carrier phase multipath through multiple antennas and
receivers is also presented using simulated and field data.
