摘要：
To solve the signal leakage in the studies by Gravity Recovery and Climate Experiment (GRACE) on global or regional mass changes, most scholars used signal inversion methods to recover the true surface mass change. Time-varying gravity signal inversion is one of the core key technologies in GRACE-based studies. However, at present, there are numerous inversion methods, such as single scale factor method, variable scale factor method, Forward Modeling, frequency-domain inversion method, space domain least-squares inversion method, etc. The commonalities, differences, and applicability among them are still not clear, which is an important scientific and technical problem to be solved. Therefore, the progress of the inversion methods of GRACE gravity signal was summarized which was widely used, the existing problems were discussed, the advantages and disadvantages of different inversion methods and differences in application fields were compared, the idea of inversion method selection was provided, and the future development trend of gravity satellites was projected, so as to provide scientific reference and suggestion about the application of satellite gravity. © 2022 Huazhong University of Science and Technology.
