| Abstract: | Superconducting gravity instrument takes the advantage of superconductivity to measure the temporal gravity. It works at 4.2K liquid Helium temperature and has the characteristics of low intrinsic noise and excellent stability. In this paper, the working principles and technical characteristics of superconducting gravimeter and superconducting gravity gradiometer are described. The development of superconducting gravity instrument in the author''s research group is briefly introduced. Finally, the opportunities and challenges faced by the development of aeronautical superconducting gravity gradiometer for resource exploration in China are analyzed, and the strategies and methods to meet the technical challenges are put forward. |
