Abstract For the purpose of quantified evaluation of the dynamic performance index of the aeromagnetic measurement system, the back-and-forth repeated linear measurement style is usually adopted to test the working stability and consistency of the system; nevertheless, there exist no definite quantified criteria for repeated linear measurement data in the standards available. In this paper, the author made an objective analysis of the reasons for the deviation of the repeated linear magnetic field measurement data, summed up the calculation method for the mean-square deviation of the aeromagnetic repeated linear measurement data and compiled corresponding calculation software. According to the calculation results of the mean-square deviation interior coincidence precision of the repeated linear measurement data, the dynamic measurement precision index and the working condition of the instrument was evaluated objectively.
