This log contains the receiver’s best available position and velocity in ECEF coordinates. The position and velocity status fields indicate whether or not the corresponding data is valid. See Figure: The WGS84 ECEF Coordinate System, for a definition of the ECEF coordinates.
See also the BESTPOS log and BESTVEL log.
The position coordinates are provided in the datum configured by the OUTPUTDATUM command.

Origin = 
Earth's center of mass 
Z‑Axis = 
Parallel to the direction of the Conventional Terrestrial Pole (CTP) for polar motion, as defined by the Bureau International de l'Heure (BIH) on the basis of the coordinates adopted for the BIH stations. 
XAxis = 
Intersection of the WGS 84 Reference Meridian Plane and the plane of the CTP's Equator, the Reference Meridian being parallel to the Zero Meridian defined by the BIH on the basis of the coordinates adopted for the BIH stations. 
YAxis = 
Completes a righthanded, earthcentered, earthfixed (ECEF) orthogonal coordinate system, measured in the plane of the CTP Equator, 90° East of the XAxis. 
These definitions are analogous to the BIH Defined Conventional Terrestrial System (CTS), or BTS, 1984.0.
