Validation of GOCE global gravity eld models using terrestrial gravity data in Norway
The GOCE (Gravity eld and steady-state Ocean Circulation Explorer) satellite gravity gradiometry mission maps the Earth’s gravity eld. Harmonic analysis of GOCE observations provides a global gravity eldmodel (GGFM). Three theoretical strategies, namely the direct, the space-wise and the time-wise approach, have been proposed for GOCE harmonic analysis. Based on these threemethods, several GGFM...

فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...
15 صفحه اولCombination of GOCE gravity gradients in regional gravity field modelling using radial basis functions
The satellite gravity mission GOCE measured the second-order derivatives of the Earth’s gravitational potential with high accuracy. The GOCE data enrich our gravity field knowledge especially at spatial resolutions from 750km down to 80km. In this paper we carry out regional gravity field analysis using radial localising basis functions that permit the combination of different data types tailor...
متن کاملGlobal Gravity Field Determination by Combining Goce and Complementary Data
GOCE gravity fields define a new standard concerning spectral resolution of satellite-only models, and provide a very high precision in the longand medium wavelength part of the gravity field up to a spherical harmonic degree of about 250. Combining GOCE with GRACE data, which gives in addition very accurate information for the long wavelength part, results in the current performance status of ...
متن کاملExternal calibration of GOCE accelerations to improve derived gravitational gradients
The aim of ESA's satellite mission GOCE is to determine the Earth's gravity field with high accuracy and resolution. To achieve this aim, GOCE carries a gravitational gradiometer that needs calibration. Existing global gravity fieldmodels in combinationwith GOCE star sensor data may be used to synthesize reference differential accelerations with which the common and differential accelerations, ...
