Abstract:
This paper describes a set of MATLAB functions currently being developed for
Space Based Augmentation System (SBAS) availability analysis. This toolset
includes simulation algorithms that are constantly being developed and updated
by various working groups. This set of functions is intended for use as a fast,
accurate, and highly customizable experimental test bed for algorithm development.
A user-friendly interface has also been developed for the tool. It is open source
and can be downloaded from the Stanford GPS Research Laboratory web site
(http://waas.stanford.edu/~wwu/maast/maast.html). Therefore, it provides a common
ground for different working groups to compare their results. This paper demonstrates
the utility of this toolset by analyzing the SBAS service volume models for the
Conterminous United States (CONUS). The paper describes the functionality provided
within the software, and shows an example set of contour plots which are the means
for investigating how different algorithms and parameters impact availability.
