This presentation will provide an overview of of the multipath
problem in GPS and DGPS applications. Multipath is the phenomenon
whereby multiple signals from a single transmitter arrive at
a receiver via reflection and diffraction. All signals other
than the direct signal are unwanted and cause distortion of
the direct signal leading to pseudorange and carrier-phase measurement
errors. This presentation will cover the description of multipath,
its effects in traditional and modern receivers, and methods
for mitigation.
