EarthPosition Struct Reference

## Detailed Description

This structure stores the location of a point on (or near) the surface of the Earth in both geodetic and geocentric coordinates, as described in TerrestrialCoordinates.c .

Definition at line 81 of file SkyCoordinates.h.

## Data Fields

SkyPosition geodetic
The geographic coordinates of the upward vertical direction from the point; that is, the point's geodetic latitude and longitude. More...

REAL8 elevation
The vertical distance of the point above the reference ellipsoid, in metres. More...

REAL8 x

REAL8 y

REAL8 z
The Earth-fixed geocentric Cartesian coordinates of the point, in metres. More...

The distance of the point from the geocentre, in metres. More...

SkyPosition geocentric
The geographic coordinates of the direction from the centre of the Earth through the point; that is, the point's geocentric latitude and longitude. More...
