Abstract
Dynamic gravity measurements can quickly yield gravity grid data with unified accuracy, which is important for rapidly modeling the regional geoids and elaborating resource exploration technologies. A superconducting gravimeter is a relative gravimeter featuring highest precision and highest spatial resolution. Studies of the technology of dynamic measurements by means of superconducting gravimeters is of great significance for improving the accuracy of dynamic gravity measurements. The article discusses the key factors affecting the dynamic measurements carried out by means of a superconducting gravimeter. The superconducting gravimeter operation principle is described. The effect the carrier vertical disturbance acceleration has on the measurement results produced by the superconducting gravimeter is analyzed based on the forced vibration equation. The law of output differential capacitance variation caused by horizontal disturbance acceleration is studied. The Eotvos effect connected with operation of the superconducting gravimeter is studied by analyzing the influence of the carrier speed and heading angle on the superconducting gravimeter output data. The study results serve as a basis for optimizing the magnetic levitation system of superconducting gravimeters and extracting dynamic signals.
