The degree of conformity between the measured parameter at a given time and its true parameter at that time. The term parameter includes: position, coordinates, velocity, time, angle, etc.

– Absolute accuracy (Geodetic or Geographic accuracy). The accuracy of a position estimate with respect to the geographic or geodetic coordinates of the Earth.
– Geodetic or Geographic accuracy. See absolute accuracy.
– Predictable accuracy. The accuracy with which a position can be defined when the predicted errors have been taken into account. It therefore depends on the state of knowledge of the error sources. (Originate: NAVGUIDE 2023)
– Relative accuracy. The accuracy with which a user can determine position relative to that of another user of the same navigation system at the same time.
– Repeatable accuracy. The accuracy with which a user can return to a position whose coordinates have been measured at a previous time using uncorrelated measurements from the same navigation system.
