For those who're still interested in further liberating their GTA01's:

I've just stumbled over the project, which
implements a full GPS solution based on SDR (software defined radio) -
all in Free Software.

This is actually more than the proprietary GlobalLocate software does,
since the Hammerhead chip already contains corellators (and potentially
other parts of the entire signal processing required for GPS RX.

It would still be quite a bit of work to get this to work, mostly due to
the fact that the Hammerhead register set and command language are not
publicly known.  Still, I thought if somebody wanted to do some work on
this, it might help to know that the remaining 90% of the problem have
already been solved by

Just to make this clear again: GTA02 doesn't have any proprietary GPS
software bits.  Please don't confuse those two devices!
