%X In order to quantitatively evaluate the performance index of airborne gravity system,repeated flight lines are usually used to test the coherence of dynamic survey of airborne gravimeter.However,there is no corresponding criterion in the current code to evaluate the quality of testing data of repeated lines of airborne gravity survey.We research and summarize a method of RMS(root mean square)accuracy calculation for testing data of repeat lines.Based on the calculation results of internal and external accord accuracy,we can objectively evaluate the dynamic accuracy index and working status of instrument.
