Hi Dieter,
Interesting device, I wasn't aware of it (I know
about the book).
Is the Source Code of the book available ? So far I have only
seen some material for download at the following site, not sure
if there is the whole content of the DVD:
http://kom.aau.dk/project/softgps/
The (blue) receiver is the old dongle sold by SparkFun during
the last years. I only remember from visiting their website, but
don't own one. I don't know if the DVD contains more than
the matlab code that can be downloaded.

This site (from 2003)...
http://home.earthlink.net/~cwkelley/
...explains the calculation in the "Operations" section, it's
a rather concise summary of the basic math involved.
I had a short look at some but always had the
impression that
it is not exactly what I am looking for. I guess I should try
to get a GPS receiver which provides the required data, thats
probably the easiest approach.
http://home.tiscali.nl/samsvl/oemtable.htm has a table comparing
various chipsets, some are quite ancient.
