GPS Features 
The vehicle speed is based on the accuracy of each GPS recorded point which can be off by 10 
meters in any direction.  What you want to look for is a trend.  If a point veers off suddenly in a 
random direction (i.e. off the road), then it's probably not valid.  If you have a sudden low or high 
speed reading, then this may point to an inaccurate speed reading. Otherwise, if you see consistent 
acceleration and deceleration, it's probably accurate. 
GPS has many variables which can affect it’s accuracy: 
Are you getting a full view of the sky from the vehicle or antenna location?
Do you have tall buildings or trees around?
Is the weather cloudy?
Other factors may contribute to inaccurate GPS.
