| pos.eop.xp pos.eop.yp |
Polar motion |
These coordinates represent the polar motion of the celestial intermediate pole with respect to the terrestrial crust |
| pos.eop.UT1mUTC |
UT1-UTC |
This parameter represents the diurnal rotation around the celestial intermediate pole |
| pos.eop.dX pos.eop.dY |
The celestial pole offsets |
The precession-nutation of the figure axis in space |
| pos.nutation |
nutation quantities |
equivalent to pos.precess |
| pos.topocentric.north pos.topocentric.east pos.topocentric.up |
Coordinates in a topocentric frame |
We suggest to introduce this local frame which is intensively used in the domain of terrestrial reference frames |
