the accuracy of a measurement between two points (i.e. the accuracy of one point measured relative to another)
The accuracy with which a user can determine position in relation to another user of the same navigation system at the same time.
A measure of accuracy (typically in LSBs) of an A/D converter. It includes all non-linearity and quantization errors. It does not include gain and offset errors of the measurement circuitry. As a measurement, it is the deviation of the measured data from the ideal data relative to a straight line drawn through the measured endpoints.
