You are correct. Precision is how close each of the data points are to each other and accuracy is how close to the target the data points are. Just be carful with how you take your data points. New GPS units use more than just the GPS locations now. So I would check each of the channels and see what data it is gathering and what data is inferred.
With qualifications and suitably modified, this is correct: the standard deviation measures spread, which is inversely related to precision, while the vectors (not distances) to the reference points measure inaccuracy. Discussion With only five readings per location several problems will arise: The standard deviations of the coordinates will vary--by a ...
