GB/T 39267-2020 Beidou satellite navigation terminology
3 Terms, definitions and abbreviations
3.1 Terms and definitions
The following terms and definitions defined in GB/T 39267-2020 apply to this document.
3.1.1
International terrestrial reference frame; ITRF
The coordinates and velocities of a set of global geodetic observation stations used to realize the International Earth Reference System.
3.1.2
Reference ellipsoid
The size and shape are defined by the semi-major axis of the equator and the oblateness, which represents the spheroid of the earth and is positioned and oriented.
3.1.3
Earth's gravityfield
A collection of earth position, gravity, geoid (or similar geoid), vertical deviation, etc.
3.1.4
2000 China geodetic coordinate system Chinageodeticcoordinatesystem2000; CGCS2000
The geodetic coordinate system established by China. The origin of its coordinate system is at the center of mass of the earth, and the Z axis points to the International Earth Rotation Service (IERS)
The defined reference pole (IRP) direction, the X axis is the reference meridian (IRM) defined by IERS and the equatorial plane that passes through the origin and is orthogonal to the Z axis
The Y-axis meets the right-hand rule.

3.1.5
BeiDou coordinate system; BDCS
Beidou satellite navigation system coordinate system coordinatesystemofBeiDounavigationsatelitesystem
The geodetic coordinate system adopted by the Beidou Satellite Navigation System (BDS). The definition of BDCS complies with the International Earth Rotation Service (IERS) specification,
Consistent with the definition of CGCS2000.
