The study of satellite gravity and the Earth's gravity field is an important research field of international geodesy, which not only drives the development of geodesy itself, but also obtains important scientific applications in related scientific fields. Taking the scientific papers in this field in the Web of Science core collection database during the 20 years from January 2000 to September 2020 as the research object, using the bibliometric methods and CiteSpace, this paper analyzes the current research status, development context and research hotspots of this field. The results show that the number of literatures on satellite gravity and the Earth's gravity field has been increasing year by year, and has maintained a high level since 2016, and the United States, Germany and China rank among the top three in the world. The top three research institutions with the largest number of papers published are Chinese Academy of Sciences, California Institute of Technology and NASA. China's research efforts in the fields of satellite gravity and the Earth's gravity field are relatively concentrated. The number of papers published by the Chinese Academy of Sciences, Wuhan University and the University of the Chinese Academy of Sciences accounts for 75.36% of China's total number in this field. Using the data of GRACE and the spherical harmonic function to construct high-precision Earth's gravity field model, as well as retrieving local mass change, is the current international research hotspot. Thanks to the satellite gravity observation data, the global gravity field model has been substantially improved.
