I wrote an article with instructions to run GPS Toolkit applications on the
Gumstix. You may find it at:
The GPS Toolkit is an open source project initiated by the Applied Research
Laboratories (University of Texas) and aiming to provide a world class, open
GNSS library computing suite. It supplies several GNSS algorithms and models,
supports RINEX and SP3 formats, and has several categories of functions and
routines such as GNSS time conversion, ephemeris computations, atmospheric
models, data extraction, weighting algorithms, positioning solutions, etc.
Please beware that the use of the GPSstix with the GPSTk has not been tried
