The ESA explorer center undertaking GOCE, to be introduced in 2006, will improve our wisdom of the worldwide static gravity box and of the geoid by way of orders of significance. The U.S. satellite tv for pc gravity undertaking GRACE (2002-2006) is at present measuring, additionally, the temporal adaptations of the gravity box. With those new info a complete diversity of interesting new chances might be opened for reliable Earth physics, oceanography, geodesy and sea-level learn. the hot new release of gravity missions employs sensor recommendations for gravity box dimension, orbit and angle keep an eye on and orbit decision that express fascinating similarities with area experiments deliberate within the box of basic physics. This quantity is the results of a workshop that introduced jointly a few 50 stated specialists of their box to debate (1) concepts for extremely precision orbit choice and gravity box modelling with the knowledge of the approaching gravity box missions, (2) using actual and excessive answer gravity types in Earth sciences wherein, specifically, synergy is predicted among a few of the technology fields of their use of this sort of new info, and (3) gravity box standards and attainable sensor and challenge recommendations for the time after GRACE and GOCE.

Example text

Residuals of the kinematic positions for the double-difference solution with float ambiguities are given for the three components on the left-hand side of Figure 4. The corresponding values for the solution with the ambiguities fixed to their integer values using the wide-Iane/narrow-Iane approach are given on the right-hand side ofthe same figure. The systematic excursions of the residuals almost completely disappear when the ambiguities are fixed. Results ofthis kind are the motivation to develop operational strategies for ambiguity resolution for baselines involving a spaceborne receiver.

Combined Processing of GPS and LEO The strategies in the previous sections were all discussed under the premise that the orbits of the GPS satellites are introduced as a priori known. In this two-step approach the GPS orbits are computed independently of the determination of the 24 U. HUGENTOBLER AND G. 20 Cross-track RSS LEO orbit. Maximum advantage may, however, be made of the complete set of GPS observations by estimating orbits for GPS satellites and LEO in a common parameter estimation procedure.

Moreover, eqn. (3) is not expanded in eccentricity. Thus only the four aforementioned variables are used. The mapping V t--+ f is represented in the spectral domain by a specific transfer hfnjk' In this case f is not limited to isotropic functionals. Combined with a dimensioning factor, an upward continuation term and an inclination function, we obtain the transfer coefficient H/~k' Every functional is characterized spectrally by its own transfer coefficient. The corresponding series expression of the functional f can be written in a two-stage formulation too: feu, A, r, /) = " " A mk 1 (r ~~ ' ,,1 H m ~ /) ei(ku+ mA) , (4a) k lmk (r, /) Kim .
