GPS Mod Driver 3.16 – GeoCaching, Lag, Compass, Cell Tower, Altitude, GPS support
This Driver installs between your GPS application and the GPSID driver that reads the hardware GPS data. Lag is compensated, by guessing your position ‘some number’ of milliseconds in the future, current course and speed changes are included in the guess. It corrects for invalid data in the GPS strings, Out of range DOP values, and Heading values of ‘NaN’ (Not A Number). Position, Speed, and course are reported, even though the distance traveled is less than 30 meters.
