| Session Title | Gravity Field Modeling Using Space Techniques |
| Main Convener | Dr. Sean Bruinsma (CNES (French Space Agency), France) |
| Co-convener(s) | Dr. Thomas Gruber (Technical University of Munich, Germany) Dr. Noriyuki Namiki (Kyushu University, Japan) |
| Session Description | The objective of the proposed session is to provide a forum for presentation and discussion related to recent advances in the field of gravity field modeling of the Earth but also the solar system bodies, as well as future mission concepts. The satellite missions CHAMP, and GRACE in particular, have increased the accuracy of terrestrial gravity field models by an order of magnitude, thereby contributing to such disciplines as hydrology, oceanography/altimetry, glaciology, and solid Earth physics. GOCE, ESA’s gravity field mission, will further improve our knowledge of the gravity field, employing the concept of satellite gravity gradiometry. Much progress has been made in lunar and planetary gravity field modeling as well, thanks to such missions as for example Kaguya, Mars Global Surveyor and Mars Reconnaissance Orbiter. In the near future, the gravity field of several other solar system bodies will be mapped, e.g., the Russian Phobos mission, or the asteroid 67P by Rosetta. Simulation studies of future gravity field missions, taking into account the limitations of the current observing systems, proposing new technologies or mission concepts, such as constellations, are also welcome. |
