In order to evaluate the performance index of the airborne gravity system, researchers usually use the method for calculating the internal accord accuracy of repeated flight lines. The authors have designed a method for precise calculation of the corresponding point of repeat lines, in which the gravity value is calculated by using interpolation. High precision internal accord accuracy could be achieved by using RMS calculation for gravity value of corresponding points on repeat lines.
