The GeoForschungsZentrum Potsdam/Groupe de Recherche de Gèodésie Spatiale satellite-only and combined gravity field models: EIGEN-GL04S1 and EIGEN-GL04C
Christoph Förste,Roland Schmidt,R. Stubenvoll,Frank Flechtner,Ulrich Meyer,Rolf König,H. Neumayer,Richard Biancale,Jean-Michel Lemoine,Sean Bruinsma,Sylvain Loyer,Franz Barthelmes,Saskia Esselborn +12 more
TL;DR: In this article, a satellite-only global gravity field model called EIGEN-GL04S1 was derived by combination of the latest GFZ Potsdam GRACE-only (EIGENGRACE04S) and GRGS Toulouse mean field solutions.
Journal ArticleDOI
A high‐quality global gravity field model from CHAMP GPS tracking data and accelerometry (EIGEN‐1S)
Christoph Reigber,Georges Balmino,Peter Schwintzer,Richard Biancale,A. Bode,Jean-Michel Lemoine,Rolf König,Sylvain Loyer,H. Neumayer,Jean-Charles Marty,Franz Barthelmes,Felix Perosanz,Shen Yuan Zhu +12 more
TL;DR: In this paper, a new long-wavelength global gravity field model, called EIGEN-1S, has been prepared in a joint German-French effort, which is derived solely from analysis of satellite orbit perturbations, independent of oceanic and continental surface gravity data.
Journal ArticleDOI
Zero-difference GPS ambiguity resolution at CNES–CLS IGS Analysis Center
TL;DR: The theoretical background, the strategies and the models used to compute the products that are submitted weekly to the IGS, and the two-step, ambiguity-fixing scheme (wide-lane and narrow-lane) is described in detail.
Journal ArticleDOI
Temporal gravity field models inferred from GRACE data
Jean-Michel Lemoine,Sean Bruinsma,Sylvain Loyer,Richard Biancale,Jean-Charles Marty,Felix Perosanz,Georges Balmino +6 more
TL;DR: In this paper, the EIGEN-GL04S gravity field model is used as the mean field to which all 10-day solutions are compared in order to infer temporal variations.
Journal ArticleDOI
The CHAMP-only earth gravity field model EIGEN-2
Ch. Reigber,Peter Schwintzer,Karl-Hans Neumayer,Franz Barthelmes,Rolf König,C. Förste,Georges Balmino,Richard Biancale,Jean-Michel Lemoine,Sylvain Loyer,Sean Bruinsma,Felix Perosanz,T. Fayard +12 more
TL;DR: In this paper, a new long-wavelength global gravity field model, called EIGEN-2, has been derived in a German/French effort using GPS-CHAMP satellite-to-satellite tracking and on-board accelerometer data over a time span of altogether six months.
