PXYA/B Computed Cartesian Coordinate Position
This log contains the last valid position, expressed in Cartesian x-y-z space coordinates, relative to the center of
the Earth. The positions expressed in this log are always relative to WGS84, regardless of the setting of the
DATUM or USERDATUM command. See Figure D-2, Page 187 for a definition of the coordinates.
PXYA
Structure:
1This log provides differential fix and age status.
