【摘要】：正CHAMP、GRACE和GOCE等衛(wèi)星重力任務(wù)的成功實(shí)施,為大地測(cè)量學(xué)、冰川學(xué)、海洋學(xué)、水文學(xué)等學(xué)科提供了諸多高時(shí)空分辨率的地球重力場(chǎng)模型。由于GRACE對(duì)地球重力場(chǎng)的長(zhǎng)波段信號(hào)十分敏感,且能以較高的精度恢復(fù)中波段重力場(chǎng)信號(hào),因此應(yīng)用GRACE重力數(shù)據(jù)恢復(fù)時(shí)變與靜態(tài)地球重力場(chǎng),一直以來備受大地測(cè)量學(xué)者關(guān)注。本文在經(jīng)典短弧積分法的基礎(chǔ)上,對(duì)重力場(chǎng)反演理論和方法作進(jìn)一步的探討和改進(jìn),并用GRACE實(shí)測(cè)數(shù)據(jù)解算了靜態(tài)和時(shí)變重力場(chǎng)模型,主要研究成果
[Abstract]:The successful implementation of satellite gravity missions, such as Grace and GOCE, provides many high-space-time resolution Earth gravity field models for geodesy, glaciology, oceanography and hydrology.Because GRACE is very sensitive to the long band signal of the earth's gravity field and can recover the medium-band gravity field signal with high accuracy, the application of GRACE gravity data to the restoration of time-varying and static earth gravity field has been paid close attention to by geodetic researchers.Based on the classical short-arc integral method, the theory and method of gravity field inversion are further discussed and improved in this paper, and the static and time-varying gravity field models are solved by using GRACE measured data.
