I'm not sure at what level of raw GPS data you intend to start, strictly speaking 'raw' GPS data usually refers to the pseudo range satellite data that can be used to calculate a Latitude / Longitude, however I'm guessing you intend to start with the Lat. / Long. Coordinates that are output from most GPS chipsets in the form of NMEA sentences eg :-
$GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47
Both of these calculations are beyond my understanding, however raw data to Lat. / Long. is covered here :-

Distance (speed) from Lat. / Long. is covered here :-
