Example

GpsKalmanFilter f = new GpsKalmanFilter(1.0);

/* Move at a constant speed */ double lat = 0; double long = 0; for (int i = 0; i < 20; ++i) { lat += 0.0001; long += 0.0001; f.updateVelocity(lat, long, 1.0 /seconds since last update/);

// Get the smoothed lat/long
double elat = f.getLat();
double elon = f.getLong();

// Get the smoothed lat/long speed per second
double dlat = f.getVelocityLat();
double dlon = f.getVelocityLong();

}
