Tools
MAAST: Matlab Algorithm Availability Simulation Tool
MAAST is a publicly available, customizable MATLAB toolset for simulating WAAS confidence estimation algorithms and
evaluating their effects on service availability.
SUGL: Stanford University GPS Laboratory ephemeris files. These files are in RINEX format
and contain GPS navigation data that have been processed as described in Dr. Liang Heng's
thesis. They are derived from the IGS
navigation data files which are then cross-compared to eliminate erroneous data. These files have not all been manually validated
and may still contain some incorrect information.
SGMP: Stanford GPS/GNSS Matlab Platform is an integrated research platform for
utilizing numerous positioning databases. It is intended to function as a platform providing an universal access
to various formats of GPS/GNSS data such as NSTB, NMEA, and RINEX. Example databases include the NSTB stations
that collect GPS information continuously in tens of sites and web-available and open to public.
