Closed formulas for the field of a rotating biaxial ellipsoid are also derived in polar coordinates and the parameters are specialized to give the International Gravity Formula values on the International Ellipsoid. By means of these formulas, and using the present gravity information, we obtain MG ...
Here, the chapter is begun with an example, namely, with a datum transformation in terms of spherical harmonics in Sect. 10 . The hard work begins with Sect. 11 to formulate the datum transformation in ellipsoidal coordinates/ellipsoidal harmonics! The highlight is Sect. 12 with the ...
In Part 2, this expression is transformed to a function of time and the Earth-fixed coordinates of the atomic clock. 展开 关键词: Atomic Clocks Reference Systems Solar System Space-Time Functions Time Measurement Universal Time Astronomical Coordinates Earth Surface Relativity Very Long Base ...
The Role of GPS in the Study of Global Change The Global Positioning System (GPS) may be used today as a mature technique in geodesy and geodynamics. Thanks to the orbits, the Earth orientation parameters, and the coordinates and velocities of about 100 IGS (International GPS Servic... M ...

The two focal points of the best-fitting, Earth-centered ellipsoid are located in the equator about E = 522 km from the center of the Earth. A given linear eccentricity, E, defines the corresponding set of coordinates, as described in Figure 2. The longitude is the same as in the ...
IRBEM-LIB provides routines to compute magnetic coordinates for any location in the Earth's magnetic field, to perform coordinate conversions, to evaluate geophysics/space-physics models, and to propagate orbits in time. - PRBEM/IRBEM
Ephemeris data are presented for 1975 and 1976 to provide a time history of lunar coordinates and related geometric information. A Manned Spacecraft Center modification of the Jet Propulsion Laboratory ephemeris tape was used to calculate and plot coordinates of the earth, moon, and sun. The ephem...
