Samsung Galaxy S2 uses
GSD4t GPS chipset,
which does not use regular SiRF binary protocol, but some new variant, which is not yet supported by gpsd
(as of 2014-06-22 gpsd v.3.10+dev3~d6b65b48-1)
The aim of this project is to create helpful scripts and instructions to help reverse engineer the new protocol,
and make a converter to regular SiRF binary protocol (or NMEA).
As of 2015-01-05, much of the data has been reverse engineered, and it seems
that the hardware is really dumb; so all processing (downloading ephemeris,
calculation pseudoranges, solving GPS location etc.) would have to be done
completely in software.
