ACCURACY: WHAT IS IT? WHY DO I NEED IT?HOW MUCH DO I NEED?

J. F. Roeber

Peer Reviewed

Abstract: Definitions are provided for the various types of accuracy (repeatable, relational and geodetic or absolute). A discussion of the many statistical bases for accuracy statements follows. These are discussed both as to how they relate to each other, and how they relate to the navigators’ frame of reference. All to often accuracy, and other requirements are based on desire, with little regard for reality (How much accuracy do I need?-“As much as I can get.“). Some suggestions, tempered with reality, are made as to how much accuracy is needed.
