within the contemporary years, space-based commentary equipment have resulted in a subst- tially superior realizing of Earth procedure. Geodesy and geophysics are contributing to this improvement via measuring the temporal and spatial va- ations of the Earth’s form, gravity ?eld, and magnetic ?eld, in addition to at- sphere density. within the body of the GermanR&D programmeGEOTECHNO- LOGIEN,researchprojectshavebeen launchedin2002relatedto the satellite tv for pc missions CHAMP, GRACE and ESA’s deliberate challenge GOCE, to comp- mentary terrestrial and airborne sensor structures and to constant and strong high-precision worldwide reference structures for satellite tv for pc and different thoughts. within the preliminary 3-year section of the examine programme (2002-2004), new gravity ?eld versions were computed from CHAMP and charm information which outperform earlier types in accuracy through as much as orders of m- nitude for the lengthy and medium wavelengths. a unique spotlight is the - termination of seasonal gravity adaptations attributable to alterations in continental water plenty. For GOCE, to be introduced in 2006, new gravity ?eld research tools are lower than improvement and built-in into the ESA processing s- tem. 200,000 GPS radio occultation pro?les, saw by means of CHAMP, were processed on an operational foundation. They signify new and ideal inf- mation on atmospheric refractivity, temperature and water vapor. those new advancements require geodetic area innovations (such as VLBI, SLR, LLR, GPS) to be mixed and synchronized as though being one worldwide instrument.
