Geodynamic/Earth-System Missions

  • Herbert J. Kramer


CHAMP is a German BMBF-funded geophysical minisatellite mission of GFZ (GeoFors-chungsZentrum, Potsdam, Germany) in cooperation with DLR. The satellite was built by the German space industry with the intent to foster high-tech capabilities especially in the East-German space industry. The S/C prime contractor is DJO (Jena Optronic GmbH) in Jena, a daughter of DASA (now Astrium). The overall science objectives are in the following fields of investigation:
  • Global long- to medium-wavelength recovery of the static and time variable earth gravity field from orbit perturbation analyses for use in geophysics (solid Earth), geodesy (reference surface), and oceanography (ocean currents and climate), supported by a feasibility test of GPS altimetry for ocean and ice surface monitoring

  • Global Earth magnetic field recovery (solid Earth and solar-terrestrial physics)

  • Atmosphere/ionosphere sounding by GPS radio occultation with applications in weather forecasting, navigation, space weather, and global climate change.

    Armand Fizeau (1819 – 1896) is a French physicist noted for the first experimental determination of the speed of light in 1849. He used a beam of light reflected from a mirror 8 km away. The beam passed through the gaps between the teeth of a rapidly rotating wheel. The speed of the wheel was increased until the returning light passed through the next gap and could be seen. Then “c” was calculated to be 315,000 km/s. Leon Foucault improved on this a year later by using rotating mirrors and got the much more accurate answer of 298,000 km/s. Fizeau’s technique was good enough to confirm that light travels slower in water than in air.Google Scholar
