Abstract: | Knowledge of the local direction of multipath at a particular site is important for a number of reasons. For example, such
information can be used to study site selections or during monument design for GPS installations. We present a MATLAB program
for creating colorized polar maps of high-frequency multipath using TEQC report files of single-epoch data. The maps, although
not necessarily indicating the actual local direction of multipath on the ground, give the orientation with respect to the
geometry of the satellites in the sky. This information can aid the interpretation of ground multipath geometry at the site.
We give an example of short-span data with ∼0.05 Hz multipath (i.e. repeat period ≈ 20 s) although the program can be modified
for long-term measurements as well. |
