The Role of GPS in Space Geodesy

1998
GPS may be considered a fully mature space geodetic technique in 1997. Some people even would say that GPS is the dominant technique in geodesy and geodynamics. Certainly, when reading this book, one must be impressed with the achievements of GPS in geodesy and geodynamics.

Global Tectonics and Space Geodesy

Science, 1992
Much of the success of plate tectonics can be attributed to the near rigidity of tectonic plates and the availability of data that describe the rates and directions of motion across narrow plate boundaries ∼1 to 60 kilometers wide. Nonetheless, many plate boundaries in both continental and oceanic lithosphere are not narrow but are hundreds to ...

Space weather impacts on Geodesy

2022
<p>Space Weather refers to events on the Sun that have an impact on terrestrial technologies and man-made satellites. The Global Navigation Satellite System (GNSS) is extensively used for Geodesy and is subject to Space Weather impacts in several ways.

Space Geodesy Project Report

2023
This research aimed to address the challenge of improving the reliability of the Water- GAP Global Hydrology Model (WGHM) using the Gravity Recovery and Climate Experiment (GRACE) satellite data as a benchmark. Our problem was defined by the need to align WGHM Total Water Storage Anomaly (TWSA) data more closely with the reliable GRACE satellite ...

Seismology and Space-Based Geodesy

1993
The potential of space-based geodetic measurement of crustal deformation in the context of seismology is explored. The achievements of seismological source theory and data analyses, mechanical modeling of fault zone behavior, and advances in space-based geodesy are reviewed, with emphasis on realizable contributions of space-based geodetic measurements

Twin probes for space geodesy

Il Nuovo Cimento C, 1978
Thetwin probe method, proposed by Bertotti and Colombo (1972) to get rid of nongravitational forces in interplanetary space, can be applied to a near-Earth orbit to eliminate the atmospheric drag. Two equal pairs of probes, each pair consisting of two passive, small and dense spheres of equal surface and different masses, are flown on a circular orbit ...

Contributions of VLBI to Space Geodesy

2000
The eminent importance of Very Long Baseline Interferometry (VLBI) in geodesy and geophysics is due to its connection with a quasi-inertial reference frame defined by compact extra-galactic radio sources. VLBI is unique in its ability to monitor without hypotheses all components of Earth orientation.

General Relativity and Space Geodesy

2012
Newton’s final version (published in 1726) of Philosophiae Naturalis Principia Mathematica was a great scientific achievement of the time and contained sufficient information to allow calculation of the dynamics of terrestrial and celestial bodies; it also expounded on the absolute nature of time and space.
