The accuracy term is very technical. Just bear in mind that the smaller value, the more accurate. Here is the technical definition.
We define accuracy as the radius of 68% confidence. In other words, if you draw a circle centered at this location''s latitude and longitude, and with a radius equal to the accuracy, then there is a 68% probability that the true location is inside the circle.
In statistical terms, it is assumed that location errors are random with a normal distribution, so the 68% confidence circle represents one standard deviation. Note that in practice, location errors do not always follow such a simple distribution.
