Definition
In a navigation system, the measure of the accuracy with which the system permits the user to return to a position as defined only in terms of the coordinates peculiar to that system. For example, the distance specified for the repeatable accuracy of the system such as LORAN‑C is the distance between two LORAN‑C positions established using the same stations and time‑difference readings at different times. The correlation between the geographical coordinates and the system coordinates may or may not be known.
