On Venus, major mass anomalies appear to be restricted principally to the surficial 200 km of the planet. A substantially thicker crust on Venus (70鈥 80 km), compared to the earth's (5鈥 40 km), can explain its greater range of gravity anomaly and the positive correlation of gravity ...
Results show no bias offsets or drifts even for long flights without crossovers, illustrating the force of spring gravimeters compared to stand-alone strapdown systems. Consistent r.m.s. error estimates for our surveys range from 1.5 to 2 mGal, for both internal and external comparisons. This ...
Compared to other models, the model SGG-UGM-2 shows a promising performance in the GPS/leveling validation. All GOCE-related models have similar performances both in the mainland of China and the United States, and better performances than that of EGM2008 in the mainland of China. Due to the...
Comparative measurements of man's walking and running gaits in earth and simulated lunar gravity 来自 Semantic Scholar 喜欢 0 阅读量: 47 作者:RL Harris,D. Hewes,A. A. Spady 摘要: Human walking and running performance in earth gravity compared to performance in simulated lunar gravity ...
The corrected amplitude factors and phase differences were compared with the Dehant, Defraigne and Wahr models for the response of the Earth to the tidal forces. We paid a special attention to the core resonance, trying to check if the phase lag of K<SUB>1</SUB> and ψ<SUB>1</SUB>...
Compared to the acceleration due to Earth's gravity at a point three Earth radii above the North Pole, the accelerati due to Earth's gravity at the North Pole is the same. 3times greater. 4times greater. 9times greater. ...
Irrespective of which anomaly type is used for gridding, the relevant additional correction terms are applied to yield an approximation of the mean Helmert anomaly. Regional gravimetric geoid models are then computed over Australia and compared with one another and with GPS-levelling points on the ...
Compared with the result from non-deleted observed gravity data, the deleted data can still work out acceptable result of similar precision. The numerical experiment validates the feasibility of clustering analysis method which provides a new approach to optimize observed gravity data for computing ...
For decoherence effects scaling as E2, our limits are advanced by more than six orders of magnitude beyond past measurements compared with the state of the art. This is a preview of subscription content, access via your institution Access options Access Nature and 54 other Nature Portfolio ...
Lack of an atmosphere at the Moon allows use of a single-frequency link and elimination of the accelerometer compared to the GRACE instrumentation. This paper describes the implementation, testing and performance of the instrument complement flown on the two GRAIL orbiters. 展开 关键词: GRAIL ...
