Notę: A Decca Chain Coverage Diagram is given when patterns from morę than one Chain appear on a chart. LOPs are normally theoretical ones; if Fixed Error is included, an explanatory notę is given.

			Satellite Navigation Systems
50	WGS WGS 72 WGS 84	World Geodetic System. 1972 or 1984
Notę: A notę may be shown to indicate the shifts oflatitude and longitude, in hundredths or tenths of a minutę, which shoutd be madę to satellite-derived positions (which are referred to WGS) to relate them to the chart.
