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 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.
The authors have bundled all of the sample data files and *.m files in a *.zip file (Teqcspec.zip).
