Detailed Description

A geographical location specified by latitude and longitude, horizontal and vertical accuracy, and altitude.

Only if state equals MA_LOC_QUALIFIED do the other members contain valid data.

Coordinates are in the WGS84 datum.

The horizontal accuracy is the RMS (root mean square) of east accuracy (latitudinal error in meters, 1-sigma standard deviation), north accuracy (longitudinal error in meters, 1-sigma).

The vertical accuracy is in meters in vertical direction (orthogonal to ellipsoid surface, 1-sigma standard deviation).

Accuracy values may be NaN, if accuracy is unknown.
