A type of superconducting suspension system for gravity measurement was introduced, and the principle and feasibility was discussed. System modeling and simulation analysis was carried out by ANSOFT, and optimization of structural position was finally completed. Analysis shows that, the system was exceptionally stable with a magnetic force gradient small enough to observe gravity changes. For systems with a superconducting sphere weighed of 15 g, the gravity measurement accuracy could reach 1 nano-Gal.
